Jesse and the ebay mess

by sales＠elecplus.com

I just got off the phone with Jesse at Cypress. He said he did not post the gold and tantalum items on ebay. It is someone else, trying to cast a bad name on him. I explained to him that the list would really like to work with him, and that old HP stuff is wanted. He explained that each item is put into a system, fully tested, and has warranty and follow up support if needed, so prices are not low. I explained to him that many list members can do board level repairs. I suggested a "garage sale" type scenario, where he offers as-is equip, to save the costs of paying a tech to test everything. He is open to that idea. He has pallets of old terminals and keyboards that he does not work on anymore, so no warranty. I told him that if he would test the monitor to make sure it turns on, and include a complete matching keyboard, members would prob pay about $85 plus shipping for a set. He does have a 150, and a lot of 1970s and 80s terminals and keyboards. He said he will gather them together and do a basic test and offer some out, on an as-is basis. Please understand that he is a business (for the past 30 years), and he does have to cover costs of storage, technicians, etc. No, he won't sell stuff for $5. It costs him more than that to pay someone to find the stuff and pack it. Please bear his needs in mind too.

PDP-11 ID page, a few images needed

by jnc＠mercury.lcs.mit.edu

In response to a request a couple of years back from Cindy, I've been slowly working on a page to help scrappers identify PDP-11's, and give them an idea what to look for. I have it _mostly_ done: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/PDP-11_Models.html Comments/error-checking etc welcome. Also, I still need images of a few things: -11/60 and -11/94 front consoles, the original LSI-11 card, the KDJ11-E, and most of the DEC QBUS boxes. (Yeah, I could try looking for free images, I've been busy!) Any help gratefully received! Noel

by jesse＠cypress-tech.com

Man you guys are tough... We sell this old HP stuff, thats what we do. There is no commercial or retail price in 20+ year old items. Its comes down to what we have into it, what others are selling them for, and what the demand is. Jay, I dont recall quoting you a 12920, I went back 3 years on my sent emails and I cant find it. I dont remember what the price or circumstances were. If I had that info, I could understand and explain the price that I quoted you .. but I'm glad you found what you needed... sorry if you were offended. As for me posting an intro on this site.. I have a boat load of older HP stuff and I'm always trying to find homes for. If my info or parts helps someone get the part or system they need, then its a win for everyone. I'm not some spam bot that just sends crap email out, we are a very small company thats been around for 25 years and we have a lot of knowledge with this older 1000, 3000, 9000, & Itanium hardware. Resellers get flack from everyone but small HP vendors like us help keep the wheels of this older HP machine rolling. Try to buy a 25 year old system from HP, they will try to sell you a x86.. :-) Again, it was an intro and if it offended anyone, please accept my apologies* *

Change in UNIBUS parity operation (Was: PDP-11/45 RSTS/E boot problem)

by jnc＠mercury.lcs.mit.edu

> Even better, it claims to be able to control whether the memory uses odd > or even parity! (How, for UNIBUS memory, I don't know - there's no way to do > this over the UNIBUS. So this really confused me, as the UNIBUS spec says parity is wholly within the slave device, and only an _error_ signal is transferred over the bus. E.g. from the 'pdp11 peripherals handbook', 1975 edition (pg. 5-8): "PA and PB are generated by a slave ... [it] negates PA and asserts PB to indicate a parity error ... both negated indicates no parity error. [other combinations] are conditions reserved for future use." The answer is that originally the UNIBUS parity operation was _different_, and that sometime around the introduction of the PDP-11/45, they _changed_ it, which is apparently why Appendix E, about parity in the /45, says what it does! I found the first clue in the MM11-F Core Memory Manual (DEC-11-HMFA-D - which is not online, in fact no MM11-F stuff is online, I'll have to scan it all and send it to Al); I was looking in that to see if the parity version had a CSR or not (to reply to Paul Koning), and on the subject of parity it said this: "The data bits on the bus are called BUS DPB0 and BUS DPB1." And there is nothing else on how the two parity bits are _used_ - the clear implication is that the memory just _stores_ them, and hands them to someone else (the master) over the bus, for actual use. Looking further, I found proof in the "unibus interface manual" - and moreover, the details differ between the first (DEC-11-HIAA-D) and second (DEC-11-HIAB-D) editions (both of which differ from the above)! In the first, Table 2-1 has these entries for PA and PB: "Parity Available - PA ... Indicates paritied data" and "Parity Bit - PB ... Transmits parity bit"; at the bottom of page 2-4 we find "PA indicates that the data being transferred is to use parity, and PB transmits the parity bit. Neither line is used by the KA11 processor." (Which explains why, when, after reading about parity in the MM11-F manual, I went looking for parity stuff in the KA11 which would use it, I couldn't find it!) In the second, Table 2-1 has these entries for PA and PB: "Parity Bit Low - PA ... Transmits parity bit, low byte" and "Parity Bit High - PB ... Transmits parity bit, high byte"; at the top of page 2-5 we find wholly different text >from the above, including "These lines are used by the MP11 Parity Option in conjunction with parity memories such as the MM11-FP." I looked online for more about the MP11, but could find nothing. I wonder if any were made? This later version seems to agree with that Appendix E. I tried to find an early -11/45 system manual, to see if it originally shipped with MM11-F's, but couldn't locate one - does anyone have one? The ones online (e.g. EK-1145-OP-001) are much later. It's also interesting to speculate about _why_ these changes were made; I can think of several! :-) Noel

VXT2000+

by bill.gunshannon＠hotmail.com

Bummer time.... I turned on my VXT2000+ today and after about 5 minutes there was a "pop" and a small puff of smoke from the power supply. No smell like you get from a selenium diode or other semiconductor. Now, the fan tries to run but only twitches and the led blinks slowly. No obvious blown part visible. Does anyone have a service manual for the H7109-B Power Supply? I would really like to fix this but I can't see paying $150-$250 for a replacement. (Actually, if I had that kind of money I would, but I don't!) bill

DEC Rainbow / Pro video on VGA monitors?

by marvin＠west.net

> I'm trying to find a way to get my DEC Rainbow's monochrome output onto a > newer monitor than my aging VR201 (especially since I zapped something in > it and my diagnostic efforts to date haven't fixed it). I can't remember the video output on the Rainbow, but I wanted to do something similar to have one setup for the S-100 machines. After looking on eBay (before I banned them from my use), I found a device that basically had RCA audio/video inputs with a VGA output. It also had the advantage of having an analog TV tuner built in so I could also use things like the old video games that had the Channel 3/4 output. The device is buried somewhere so I can't tell you the brand.

PDP-11/45 RSTS/E boot problem

I imagine you're busy with a soldering iron at this moment? :-) Once those are fixed, it will be interesting to see if the problems you saw with the OS's go away. It'd be easy to hack V6 to turn on parity error detection, if you'd like to. > Will have to see after I make the next round of repairs if there are > still additional problems that the MAINDEC flags that my simplistic diag > isn't shaking out.

Is this typical for vintage 4116 I don't know about 4116's, but I've seen a fairly high failure rate on _some_ cards with 256K DRAM's - on one board, a couple of chips totally dead, some others with just _some_ bad bits. Other cards were totally fine. I suspect it depends on the chip manufacturer. > Might be just a fastbus thing?

This particular text is removed from the later KB11-A,D > maintenance manual, and the description there seems to imply all reported > parity conditions trap directly to 114. Ah... Looking at the "pdp-11/45 processsor handbook", 1972 and 1973 editions, there's an "Appendix E: Memory Parity" (of which I was previously unaware!), referred to in "2.5.6 Memory Parity". (I haven't checked to see if later ones have it.) It claims there are "16 memory status registers ... each one associated with an 8K section of memory". (It doesn't say whether UNIBUS memory, Fastbus, or both!) One bit in each register claims to be 'Halt Enable': "[when] set, the machine will execute a halt if a parity error occurs"; when clear, it traps to 4! Even better, it claims to be able to control whether the memory uses odd or even parity! (How, for UNIBUS memory, I don't know - there's no way to do this over the UNIBUS. And the MM11-L and MM11-U manuals indicate they both use odd parity, although there's a CSR bit to allow wriring 'wrong' - i.e. even - parity.) Very odd. Maybe this was deleted in the hardware (or they decided not to do it), and someone forgot to follow through in the manual? I recently found another reference to a /45 CPU feature I'd never heard of - forget what it was, alas! > surprisingly, neither one of my M8106 has either a jumper or the > indicated pull-up at that location! .... The fact that W1 exists on the > M8119 is interesting; maybe the situation is that the prints are for > later revisions, and my actual M8106 are earlier? Could be. I wonder if there's any way to get ahold of the ECO list for that card? Noel

PDP-11/45 RSTS/E boot problem

by jnc＠mercury.lcs.mit.edu

> From: Paul Koning > It checks if the bits 007750 are active in the parity CSR, if so it > takes that to be an address/ECC parity CSR. That's odd; those are the 'error address' bits. Maybe there's an assumption that the sweep of memory to size it will have caused a parity error from garbage in DRAM at startup? (If so, I wonder if it would work on a machine with all core? :-) > It figures out the CSR to memory association by going through memory in > 1 kW increments ... This should set bad parity, and it scans all the > CSRs to see which one reports an error ... If no CSR has that set, it > concludes the particular block is no-parity memory. Oooh, pretty clever - good workaround for rhe undefined relationship between CSR's and memory. If I added parity support to V6, I'd be tempted to do it with a hand-configured table - devices are all manually configured anyway in V6, so I'd be continuing a theme... :-) Noel

Xerox Star emulator (Darkstar) released today

by derschjo＠gmail.com

Hi All -- Thought you folks might be interested -- I've been working on a Xerox Star emulator at LCM+L on and off over the past year and I've finally unleashed it upon the world.? It's called Darkstar, it's open source and it runs all the Star software I'm aware of.? The Ethernet interface is still mostly untested, however. You can grab the emulator and its source code on our GitHub site here:https://github.com/livingcomputermuseum/Darkstar.? Disk images are available on Bitsavers as always.? Thanks to Al for providing a lot of assistance on this project. Please let me know if you have any questions or suggestions. Thanks! Josh

VCF PNW 2019: Exhibitors (still) needed!

by mbbrutman＠brutman.com

This is not quite last call, but it is getting close ... We have 16 exhibits so far and we need a few more to make the show work. (20 would be nice, 25 would be ideal.) The event is March 23-24th in Seattle. Soon I'm going to start working on the exhibit floor plan, set the event schedule, and start to do the prep work that makes the show possible. But I need to know who is participating before I get too deep into that. If you know you are definitely going to participate then please help me out and formally register. If you have questions or are on the fence then let me know and I'll try to help you decide. Maybe this is not the right year for you, and that's fine ... but if there is something I can help you with let me know. I'm not fussy but if you can exhibit Commodore 8 bitters or Amiga equipment then I really want to talk to you. :-) (We seem to have a gap in the show there. Amazingly, nobody is doing an IBM PC related exhibit either.) A description of the event can be found at http://vcfed.org/vcf-pnw . General information for exhibitors including pictures from last year, a link to the registration form, and a FAQ can be found at http://vcfed.org/wp/vcf-pnw-exhibitor-registration/ .

Wanted: AT&T System V Release 3.2.{1,2,3} Source Code

by web＠loomcom.com

[Cross-posted from the 3B2 mailing list] Hi folks, I'm in search of source code for AT&T's System V Release 3.2.1, 3.2.2, and/or 3.2.3 for the 3B2. Does this exist? Has anyone ever seen it? Note that I'm not looking for the System V Release 3.2 Source Code Provision for the 3B2 /310 and /400 -- I already have that. It was absolutely invaluable when I was writing my 3B2/400 emulator. The reason I'm so keen on getting access is that I have ROM images from a 3B2/1000, and I'd like to add support for it to my 3B2 emulator. The system board memory map seems a bit different than the /300, /310, and /400. These max out at SVR 3.2. I can't imagine trying to add 3B2/1000 support without the 3.2.x source code. I imagine there's some tape image somewhere that's a delta of files that take you from 3.2 to 3.2.1, 3.2.2 or 3.2.3? -Seth -- Seth Morabito Poulsbo, WA, USA web at loomcom.com

cctalk Digest, Vol 52, Issue 18

by iain＠csp-partnership.co.uk

I have used Jorgs kit to get my 11/70 front panel running. There is NO NEED to split the cables - for manual circuit, nor is there in the new ?cap? adaptor board. I *THINK* Jorg has many cables and many panels and the split is a throwback to some earlier work that I saw photos of. My (wire wrapped, no using the new ?cape?) is at http://www.scotnet.co.uk/iain/DEC/1170/ <http://www.scotnet.co.uk/iain/DEC/1170/> Flat 40 pins - no split. I have not had time to document the process of the old or new board. All I can say is that the kit turned a messy job into a fairly quick and easy one. I can strongly recommend the kit to anyone. It took me two nights with the circuit list and a wire-wrap tool to set up the board in the link above. Then an elasped day footering with the test software and scope checking signals etc. With the newer 11/70 add on board I would think it would be a painless evening of work. > > Message: 2 > Date: Thu, 17 Jan 2019 13:45:19 -0500 (EST) > From: jnc at mercury.lcs.mit.edu (Noel Chiappa) > To: cctalk at classiccmp.org > Cc: jnc at mercury.lcs.mit.edu > Subject: Re: "Plug and Play" adapter for PDP-11/70 panel - BlinkenBone > update > Message-ID: <20190117184519.32C6918C0BE at mercury.lcs.mit.edu> > >> From: Jorg Hoppe > >> Now you can painlessly plug a physical 11/70 panel > > So I'm curious about the flat cables to the -11/70 console, which have been > taken apart into individual conductors.

seeking punched-card reader in Boston area

by fedorkow＠mit.edu

Greetings CCtalk, ? Does anyone in the Boston area know of a working 80-column punched-card reader? ? I'm working with a researcher at Harvard who's come across some very interesting election polling data from the 1960 Kennedy-Nixon race, punched onto about 10,000 cards (five boxes).? That's too many for manual transcription, but too few for an industrial-strength solution. ? The cards are in a professionally-managed university archive, so it's not as easy as just throwing them in a shipping box and sending them off to who-knows-where to be read. ? Some of the cards are in binary format, so I'm fine with some ad-hoc Pythonic data massaging, if I can just get the bits read. ? If anyone in the Boston area has a machine they might be able to make available, could you get in touch? ? That's fedorkow at mit.edu ? Thanks! /guy fedorkow

"Plug and Play" adapter for PDP-11/70 panel - BlinkenBone update

by jnc＠mercury.lcs.mit.edu

> From: Jorg Hoppe > Now you can painlessly plug a physical 11/70 panel So I'm curious about the flat cables to the -11/70 console, which have been taken apart into individual conductors. I am wondering why? This doesn't seem to have been done because you needed to re-order them (they turn back into flat cables before they go into the connectors - although perhaps you cross-connected a pair of wires)?

PDP 11 repairs in progress

by lyokoboy0＠gmail.com

Hello, ive been reading on the list here for a while. I'm usually in the background not seen much, I figured i would give a status update on my pdp 11/34 system. I have been moving quite often for work over the past couple years, and still have not gotten my machine running since picking it up over 3 years ago. Thankfully I have all of the equipment and peripherals in one place now, and am hoping to get this thing finally running soon. I had picked up an entire truckload of a pdp 11/34 system. Its an 11/34 with a tape drive in a separate rack, 2 rl02 drives and an rl01. Lots of disk packs and terminals. I fought with some power supply troubles at first, but after some part swapping i got the machine to power back up. As of right now, i have a minimal machine that i can key in programs on the front panel. I was able to enter programs through the front panel that would display on the vt100 connected via current loop. Thats pretty much the state of things right now. The system is in a minimal state,most of the cards are removed for troubleshooting. i wanted to test the hardware and see if i can boot to a disk packs. My disk packs appear to be loaded with RSX. I was trying to switch from current loop to rs232, so i can connect the machine to a modern computer with a serial port, and dump diagnostics over the line to test the machine. I have tried wiring up the cable, but am getting intermittent garbage on the terminal. Thats pretty much the hangup at the moment. I hope to over the weekend troubleshoot it further and get this project moving again. There is a lot of local activity here with all the hacker spaces and amateur radio folks, i really want to get it running in some kind of public manner that others can interact with, perhaps some kind of telnet gateway or over ax.25 packet, but thats later down the line once its running. There is also another 11 I am picking up in Georgia in the following week, so i have that drive ahead of me. Not even sure i will get started checking the other system out till the 34 is running. Well, thats about it for the state of things and my progress. Once i get things cleaned up a little better ill post back with some pictures of the current setup. --Devin D.

Relating to 386 / 486 motherboards wanted

by lyokoboy0＠gmail.com

About a week ago, "drlegendre" posted looking for some 386 and 486 boards. I said i had some, but was quickly overwhelmed with work and have not had time to post back till now. Should anyone else be interested, I'm putting a link to some pictures of what 386 and 486 boards i have. Some have corrosion from battery leaking, i usually clip those off, and use an external battery. If you have a board of interest in the pictures , let me know and i will clean it up and make sure it posts / checks out. I have other boards as well, for pentium, pentium pro, amd k6, 5.25 floppys, drives, etc. Plans are to get a website going with a listing of everything, but for now, if you are looking for an older system , just let me know, and ill get back to you with what i have on hand. https://postimg.cc/gallery/ebkjait6/ --Devin D.

Uh, no. The copies there are 'prototypes', later modified for actual use by adding in the actual address in main memory. Still trying to understand how that works - the code (in sureg() in main.c) is kind of obscure. Noel

DiscFerret found a new home.

by fjkraan＠xs4all.nl

Hi Everyone, The DiscFerret found a new home. I did get some questions on its usefulness, which I would address here. Indeed the software developed for it is limited to a driver and some analytical tools. But it uses the same format for flux-intervals as the CatWeasel, at different (higher) clock rates. So any open source CatWeasel program is easy to adapt to the DiscFerret. Using the provided MagPie dump program I managed to adapted Tim Mann's cw2dmk program for the CatWeasel to dfi-files (https://fjkraan.home.xs4all.nl/comp/divcomp/discferret/). Of course this only does FM, MFM and variants (DEC and Intel), but demonstrate its usefulness for archiving. It is too bad production stopped and the writing image software never materialized. BTW, reading floppy disk rate flux-changes can reliably be read with modern ~100 MHz micro-controller. Several are commercial available. AFAIK not open source. Greetings, Fred Jan

> From: Allison Parent > Most Probable cause is interrupt grant is broken. The only -11 that complains if the grant chain is broken that I know of is the /34 (maybe the /04 too).

PDP-11 Memory

by bill.gunshannon＠hotmail.com

Well, I have decided to stop playing with my hardware for a while and get back to playing with software. :-) In order to do this I am building three (maybe four) PDP-11's. I have an 11/93, an 11/73 and an 11/23+ (and maybe another 11/23 or 11/73). BUt, I have run into a small problem. Memory. (both the systems and me!) My 11/93 has 2 meg internal and I would like to bring it up to 4 meg. The others I would like to see with 4 meg if possible. (except the last one which I may deliberately keep at 128KW.) I have a number of different memory modules. Mostly DEC but a couple third party. Here's the problem. None of them are reflected in any of the documentation I have been able to find so I can't configure them away >from their defaults! Here's a list of numbers: M7551-AC - All the docs I can find seem to refer to AA or AB and jumpers and switches are not in the same locations. M8067-LB M8067-LF M8067-LJ - Same problem. I can find no documentation for any -L boards and these don't even resemble the pictures I find. And then I have two non-DEC module that are unlikely to have any documentation still floating around for. Camintonn CMV-1000 -- As funny as it sounds, this one looks more like a DEC MSV11-QA then the DEC ones do, but not exactly. And one who's maker is only identified by a logo that looks like 2 interlaced stylized S's. Model Number is: 980110014-201 Rev E. Anybody got any pointers to help me configure some of this stuff? bill

warped RK05 pack -- lost cause?

by fritzm＠fritzm.org

So, one of the things I have along with my 11/45 is an RK05 alignment cartridge. Unfortunately, its seems warped -- rides up an down a few millimeters in each direction as you turn it in an RK05 drive. :-( Is there any hope for bending one of these platters back more into true (maybe using a rig like they do with bicycle rims, etc?). Or is it just basically junk at this point? I wouldn't really care, but it's an alignment cartridge and there can't still be too many of these still around out there... So it sort of sux to just write it off. I'm assuming that if I had to release the media >from the hub in order to true it, its value as an alignment cartridge would be lost anyway. --FritzM.

I already have a large stack of empty bezels, acquired to hold the indicator panels... :-) Although Dave Bridgham has been playing with the CNC mill at his local makespace (he's already turned out a bunch of light shields for me), and he now has a prototype of a thing which combines the bezel and light shield. So maybe the empty bezels will instead get paired with blank sheets to make a stack of 1/2-width blank panels. Someone still makes that 'pebbled' sheet like what DEC used in blank panels, but we haven't acquired any yet to see just how close a match it is. (Anyone happen to know?) Noel

Netronics EX85 BASIC dump

by vintagecomputer＠bettercomputing.net

Wondering if anyone has any EPROM dumps of Netronics' BASIC for the Explorer/85. I'd like to set up my own EX/85 for that but also have this little Atlantis 8085 board that I was hoping to experiment with. I've looked all over the interwebs and have had no luck finding a dump, although I have found reference to people dumping them for backup purposes. Many thanks! Brad

warped RK05 pack -- lost cause?

by jnc＠mercury.lcs.mit.edu

> From: Fritz Mueller fritzm at fritzm.org > I'm assuming that if I had to release the media from the hub in order > to true it, its value as an alignment cartridge would be lost anyway. Yes and no.... The RK05 alignment pack is mostly to make sure that the fine lateral track adjustment is correct (i.e. that when the head thinks it's over track 0, it's _really_ over track 0). However, there's also rotational alignment (i.e. start of sector), which is done with the slits in the ring on the pack (so yes, releasing the media from the hub in an ordinary pack will make that pack unreadable - at least until it's reformatted). There is an index/sector timing adjustment procedure, and it uses the alignment pack too, but this rarely needs to be done. Still, if the platter is on wrong, the whole thing's useless anyway. So as long as the platter goes back exactly concentric (and I'm unsure of how the mechanical alignment works, there may be something to assure there's no runout), it should still be usable for the head alignment. (To use it for sector alignment, you'd have to ensure that the drive is aligned for this before-hand, then use it to align the pack.) But check the RK05 Maintenance Manual (EK-RK5JF-MM-001), and see if there's anything I missed. There's also an 'RK05 Subsystem Maintence Course' document (EY-D2055-WB-001) which might contain some useful info. Off to look at the V6 MMU setup code! ;-) Noel

Documentation for Xebec Owl (a 1984 SASI-disk-drive)

by martin＠shackspace.de

Anyone here, owning a Xebec Owl and/or its documentation? The Owl is a SASI-disk-drive from 1984. One could say that it's mostly a Xebec S1410A mounted on a drive, thus eliminating the ST-506-interface. The one I had my hands on seems to be a late version, called the Owl II (20MB instead of 10MB). It shiped with a PC-SASI-controller for the 8-bit-ISA-bus (TTL) and 4KB Boot-ROM (in a 2764-EPROM). The firmware of the Owl II itself seems to be more advanced and bigger than that of the well-known Xebec-bridge-boards: The Owl has 16KB (27128) of firmware, compared to the 4/8KB (2732/64) of a S1410/10A/20. A lot of its commands are explained in the documentation of the S1420 controller, but it seems there are some commands missing, e.g. the command 0x0C. The drive is not compatible with later SCSI equippment. The owner reported, he did not manage to run it with a "modern" PC-SCSI-Controller and I'm not surprised about this: Some commands and codes are incompatible to SCSI/CCS, so the SENSE codes. There is also a command collision with the INQUIRY command, uhhhh :( Does someone own the/some/any documentation for the Owl? It doesn't seem there's much more out there than this brochure: http://www.bitsavers.org/pdf/xebec/brochures/Xebec_Owl_Datasheet_198410xx.p… --map

The issue was confined to the integrated floating point portion of the processor and was therefore rarely an issue as the vast majority of software did not use the mathco portion of the chip. Only a handful of applications and relative handful of users were affected. This became Intel's position on the matter and they hoped the issue would just die down to those handful whom they would provide new chips. The issue did not die down and the bad press forced the decision to replace ALL pentiums affected. Only a relative few were actually replaced in the home and small business arena. A software patch was a common solution to the problem. It masssaged input to the FDIV instruction to produce a corrected result and worked pretty well as I recall. At the time of the storm, the Pentium was still pretty new and very expensive. Most folks were getting along with AMD k5 and k6 processors. I WAS. I went from k6 to Celeron. Best Jeff

[chop] I enjoyed reading the discussion regarding these bogus emails. I get a one or two per week. Some with no password, and some with a password only used for one particular site with an email address only created for that site. (and the site is no longer around more than likely due to being hacked ... essentially the account I had there was a throwaway). Some of the phishers are getting "smarter" and dropping the "-suffix" I used for the email (which also ends up getting to me ...) Obviously the system(s) they send it to don't have a camera, don't have any web browsing software installed, are text based (Linux and OpenVMS) and I just laugh. However, I do enjoy totally confusing the scammers. I have the extra password configured for the SYSTEM account on my main VMS box. The script kiddies have no idea what to do with a second password prompt (since you don't get a User Authorization Failure until you enter both passwords, good, bad, or indifferent). 34630 failures since last successful login No intrusion records either, as they try once and move on. Long passwords are looooong so I challenge them to guess. If they get in, login DCL does checks and if you don't have the secret sauce ... *plonk* I probably don't have to have extra password set, but I'm paranoid and do it anyway. I've also noticed folks at $work are starting to get these "give me bitcoins because I saw your pr0n" messages as well. Those were some fun discussions. Fred

OT? Upper limits of FSB

by technoid6502＠gmail.com

Apropos of nothing, I've been confuse for some time regarding maximum clock rates for local bus. My admittedly old information, which comes from the 3rd ed. of "High Performance Computer Architecture", a course I audited, indicates a maximum speed on the order of 1ghz for very very short trace lengths. Late model computers boast multi-hundred to multi gigahertz fsb's. Am I wrong in thinking this is an aggregate of several serial lines running at 1 to 200mhz? No straight answer has presented on searches online. So here's the question. Is maximum fsb on standard, non-optical bus still limited to a maximum of a couple of hundred megahertz, or did something happen in the last decade or two that changed things dramatically? I understand, at least think I do, that these ridiculously high frequency claims would not survive capacitance issues and RFI issues. When my brother claimed a 3.2ghz bus speed for his machine I just told him that was wrong, impossible for practical purposes, that it had to be an aggregate figure, a 'Pentium rating' sort of number rather than the actual clock speed. I envision switching bus tech akin to present networking, paralleled to sidestep the limit while keeping pin and trace counts low.....? Something like the PCIe 'lane' scheme in present use? This is surmise based on my own experience. When I was current, the way out of this limitation was fiber-optics for the bus. This was used in supercomputing and allowed interconnects of longer length at ridiculous speeds. Thanks for allowing me to entertain this question. Though it is not specifically a classic computer question, it does relate to development and history. Best, Technoid Mutant (Jeff Worley)

PDP-11/45 RSTS/E boot problem

by jnc＠mercury.lcs.mit.edu

> I don't recall off the top of my head whether the location of that > shared block of memory is in the per-process swappable kernel data > (which is included in the process core dump). So I checked, and the swappable per-process kernel data does in fact include pre-computed contents for all the memory management registers, so we'll be able to see (from the process core dump) where the code and data segments were. On another front, that error message ("Memory error") is produced when a process gets a 'memory management trap' (trap to 0250). This could be caused by any number of things (it's a pity we don't know the contents of SR0 when the trap happened, that would tell us exactly what the cause was). With working hardware+OS, it's usually the result of a bad pointer in the program. In a tested program like 'ls', I don't think that's the case. It's most likely caused by faulty memory, but it's also faintly possible that the MMU has an issue. I'll look at the process dump a little later today, and see if I see anything of significance.

It claimed my email account had been hacked and threatened all sorts of dire consequences if I didn't deposit $1000 in bitcoins in some place within 48 hours. I am 100% certain that the claims in the message are completely bogus and none of the threats will be carried out. It is likely that email addresses belonging to other list members are also to be found wherever my email address was scraped from so I just wanted to warn other list members about this scam in case they receive similar emails. (I received the scam email directly, not via the cctech listserver). Regards, Peter Coghlan.

PDP-11/45 RSTS/E boot problem

> From: Fritz Mueller PPS: > I could work to extract the core file I just checked, and the binary for the 'ls' command is what's called 'pure code'; i.e. the instructions are in a separate (potentially shared) block of memory from the process' data (un-shared). I don't recall off the top of my head whether the location of that shared block of memory is in the per-process swappable kernel data (which is included in the process core dump). I'll check tomorrow, when I'm not sick as a dog (pretty miserable right at the moment). It would be east to mod the OS to print all that info when that illegal instruction trap happens - but that will change the size of the OS, so will probably change the location the process is at; so that might cause the symptoms to change. Ditto for recompilling 'ls' to make it a unified blob. > Assuming that doesn't create another core file... :-) :-) Don't worry, we'll nail it! Noel

I just posted on github a little project that takes a cheap surplus (my last ones cost $5 NOS) IBM iPoint IR keyboard and converts it to PS/2 keyboard protocol using a cheap STM32F103 "Blue Pill" and a 3-terminal 38KHz IR receiver.? I'm currently writing the USB version which will support the "nipple mouse" as well. The keyboards aren't bad--they're made by Silitek ca. 1992 and have a decent feel for a rubber dome keyboard. The point is that with modern MCUs, any IR stuff is easy-peasy.? My little Chinese LCR tester even reads and displays IR codes. --Chuck

Anyone want an irman (Infrared to serial dongles)

While tidying up I've found a few Irman infrared to serial dongles https://web.archive.org/web/20060314052558/http://www.evation.com/irman/ind… they connect via a 9 pin serial plug and then convert any consumer remote IR signals they receive into serial. No additional power required, good wide angle reception, open source driver still available https://sourceforge.net/projects/libirman/ Could make an interesting project for anyone who wants to control their VAX / S-100 / homebrew retro board with a serial port via a remote :) The company making them went away about a decade ago, so I'm counting that as in retro territory. I have four for the price of shipping if anyone is interested, based in London/UK. (Around 2000 we had an office music system based around a DNARD/Shark running mserv & irman where everyone had a random remote at their desk and could use it to rate/skip/queue something they liked, and the system generally trid to pick from music which most of the people currently connected liked... ahh, fun days :) David

KD11-E/EA microcode flow diagrams

> From: Fritz Mueller >> the last microinstruction for RTI/RTT has been moved from 002 -> 744. > So what's at 002 now? Maybe something new was required there by micro > branch/fork logic, so the original contents had to be moved? Well, it turns out I've been transcribing the ucode flow diagrams from the 34, as part of a deeper look at the 34. (Dave B and I need a PDP-11 in the FPGA on the QSIC, to run the USB protocol on; rather than using a microcontroller, we decided the hack value of putting an -11 in there was too much to resist. It's also practical, though - we're already very familiar with it, have a good toolchain for it, etc. One option for that - we know about the existing FPGA -11's - was cloning the /34.) So according to that table: http://gunkies.org/wiki/KD11-E/EA_microcode there is no uinst at 002 now! So I have no idea why they moved it. (The place they moved it to, 0744, seems like it was the first empty location.) There is a dump of the 34A microcode here: http://www.bitsavers.org/pdf/dec/pdp11/1134/m8266_ucode.out.txt and for 002 it gives Called by......... = IR or BUT only NEXT MPC.......... = 015 but 015 doesn't seem like a useful place to branch to? Maybe location 002 was just abandoned (I have no idea why), and that's some leftover trash? BTW, the engineering drawings contain three errors (fixed in the table above; see the notes there), so I suspect they were drawn up by looking at a set of the listings. I wonder if the actual source has survived? Probably not, alas... Noel

I also have a little memory diag that I wrote myself that you could try. Let me know if you'd like it; it's currently for the /23+/73 (and it would probably work on the /70, I'd have to check) so I'd have to tweak a few things to get it to run on a /45. Best way to get it to you would be to send you the Unix assembler source, if you can get that onto the disk, then you could: as memptst.s mv a.out /memptst and just boot it. Noel

> From: Fritz Mueller > I should go read up on QSIC. There's not much on the Web, alas. We have two working prototypes (a wirewrap QBUS mother-board with bus transceivers, level converters, etc, connected to an FPGA prototyp ung card by flat cables), and working FPGA code to emulate an RK11, using a uSD card for actual storage. It's good enough that the /23 can boot and run V6. We also have working indicator panels: http://ana-3.lcs.mit.edu/~jnc/tech/DECIndicatorPanels.html but the inlay we've done: http://pdp10.froghouse.org/qsic/indicator-panel-printed.jpg is not a straight copy of an existing panel (those all have lots of lights that only make sense with a real drive, and leave out others that would be really useful, e.g. the address). Here: http://pdp10.froghouse.org/qsic/manual.pdf is the firat crack at the manual for the production version (the RP11 is not done yet). > I could really use a "USIC"... :-) That's next, after the QSIC is out.

Is that how you've gotten your authoritative version? I didn't get it, I found it on BitSavers - I assume that was what whoever provided it did. But it's actually stored in 12 4-bit wide PROMs, U95-U118 (roughly). Noel

(I already have an PDP11/70 front-panel running on the same infrastructure) I have been struggling for over a year to get much info about this saratov computer (circuit diagrams etc). So I have started the reverse engineering on the panel. Does anybody know anything about this computer? online or offline it would be much appreciated. Iain

> From: Fritz Mueller > I've thought about that; Unix V6 is actually next on my list of OS's to > try. I think I have seen a fairly detailed set of instructions on > building an image from this from the commonly available distribution > tape. Yeah, one comes with the V6 distribution: http://gunkies.org/wiki/Setting_up_UNIX_-_Sixth_Edition (That's just a 'do this and then do that' list - if you want to know what it's actually _doing_, this: http://gunkies.org/wiki/Installing_UNIX_Sixth_Edition gives the technical details.) Alas, the instructions don't have a lot of detail on how to create the /45 version (it's quite simple - basically one just includes m45.s instead of m40.s in the linker command line :-); I guess I'll do up a cheat sheet. > But if you have an RK05 image already ready to go, go ahead and send it > over and I'll give it a try! Well, there are single-RK05 images up already: http://www.tuhs.org/Archive/PDP-11/Distributions/research/Ken_Wellsch_v6/ but they only include binary for /40's (which will run on a /45 of course; they distributed only the lowest-common-denominator binary, to make their life simple; people have to build their own binary - system and commands - if they want to upgrade). But if you'd like me to make up an RK05 image with a /45 system on it too (one gets to specify what one wants to load at boot time); let me know, and I can whip it up - but really, it's drop-dead simple to build a /45 version if you have the /40 version running. Note: the pack images on the distribution tape _do not_ include the bootstrap in block 0; use the one I linked to above. > It wasn't clear to me last time I looked that I could build V6 to run > off a single pack without having a second RK05 drive and pack available > for swap? No, the image above is for a single RK drive machine; it will run that way, albeit things are a bit cramped. What it does is put a file system in blocks 1-4000, and it uses blocks 4000 and up as the swap area (I forget which one block 4000 itself goes with :-). > Day gig starts back up today after winter break, so less bandwidth for > PDP-11 hacking now unfortunately! :-( Well, at least you have something to go back to; the spousal unit works for NASA, and they're all getting an enforced extended break (much to her annoyance).

> From: Grant Taylor > Is "byte" the correct term for 6-bits? I thought a "byte" had always > been 8-bits. I don't claim wide familiary with architectural jargon from the early days, but the PDP-10 at least (I don't know about other prominent 36-bit machines such as the IBM 7094/etc, and the GE 635/645) supported 'bytes' of any size, with 'byte pointers' used in a couple of instructions which could extract and deposit 'bytes' from a word; the pointers specified the starting bit, and the width of the 'byte'. These were used for both SIXBIT (an early character encoding), and ASCII (7-bit bytes, 5 per word, with one bit left over). > I would have blindly substituted "word" in place of "byte" except for > the fact that you subsequently say "12-bit words". I don't know if > "words" is parallel on purpose, as in representing a quantity of two > 6-bit word. I think 'word' was usually used to describe the instruction size (although some machines also supported 'half-word' instructions), and also the machine's 'ordinary' length - e.g. for the accumulator(s), the quantum of data transfer to/from memory, etc. Not necessarily memory addresses, mind - on the PDP-10, those were 18 bits (i.e. half-word) - although the smallest thing _named_ by a memory addresses was usually a word.

> From: Fritz Mueller > Thanks, Noel -- I'll give that a try! Sure - always glad to help with anything V6 related - that's my chief technical amusement, now that I'm retired! :-) Any questions/issues, let me know, and I'll try and get right back. When booting UNIX, remember make sure the switches on your /45 are set to 0173030, so it comes up single-user! (Might we worth checking to see if all the bits in the SR are working, but you've probably already done that as part of bringing the machine up? I wonder if a failure there could cause the RSTS issue? It's so cool that you have a working /45! I have yet to start on mine...) And do icheck/dcheck every time you bring it up, and make sure to 'sync' before halting... These old systems are not as robust in terms of the file system! And when it gets to putting together a /45 version of the OS, that new page I just did should help. Noel

> From: Dave Wade > The only machine I know where a "byte" is not eight bits is the > Honeywell L6000 and its siblings I'm not sure why I bother to post to this list, since apparently people don't bother to read my messages. >From the "pdp10 reference handbook", 1970, section 2.3, "Byte Manipulation", page 2-15: "This set of five instructions allows the programmer to pack or unpack bytes of any length from anywhere within a word. ... The byte manipulation instructions have the standard memory reference format, but the effective address E is used to retrieve a pointer, which is used in turn to locate the byte ... The pointer has the format 0 5 6 11 12 13 14 17 18 35 P S I X Y where S is the size of the byte as a number of bits, and P as its position as the number of bits remaining at the right of the byte in the word ... To facilitate processing a series of bytes, several of the byte instructions increment the pointer, ie modify it so that it points to the next byte position in a set of memory locations. Bytes are processed from left to right in a word, so incrementing merely replaces the current value of P by P-S, unless there is insufficient space in the present location [i.e. 'word' - JNC] for another byte of the specified size (P-S < 0). In this case Y is increased by one to point at the next consecutive location, and P is set to 36 - S to point to the first byte at the left in the new location." Now imagine implementing all that in FLIP CHIPs which held transistors (this is before ICs)! Anyway, like I said, at least ITS (of the PDP-10 OS's) used this to store ASCII in words which contain five 7-bit _bytes_. I don't know if TENEX did. > I also feel the use of the term Octet was more marketing to distance > ones machines from IBM..... Huh? Which machine used the term 'octet'? Like I said, we adapted and used the term 'octet' in TCP/IP documentation (and that's definite - go check out historical documents, e.g. RFC-675 from 1974) because 'byte' was at the time ambiguous - the majority of machines on the ARPANET at that point were PDP-10's (see above). Interestingly, I see it's not defined in that document (or in the earlier RFC-635), so it must have already been in use for an 8-bit quantity? Doing a little research, there is a claim that Bob Bemer independently invented the term in 1965/66. Perhaps someone subconciously remembered his proposal, and that's the ultimate source? The term is also long used in chemistry and music, of course, so perhaps that's where it came from. Noel

I was quoting my memory of a DEC ad in the WSJ, which now that I go check, says the -11 was "the best-selling computer in the world" (the ad was in 1980). There are a number of possible explanations as to why it makes this claim: - some marketing person made it up - they were only counting things that were general-purpose (i.e. came with mass storage and compilers) - they didn't consider micros as "computers" (many were used in things like printers, etc, and were not usable as general-purpose computers) Etc, etc. Noel

off topic - capatob - saratov2 computer Russsian pdp8? HELP

by jnc＠mercury.lcs.mit.edu

> From: Guy Sotomayor Jr > I think it's also telling that the IETF uses the term octet in all of > the specifications to refer to 8-bit sized data. Yes; at the time the TCP/IP specs were done, PDP-10's were still probably the most numerous machines on the 'net, so we were careful to use 'octet'. Although the writing was clearly on the wall, which is why it's all in octets, with no support for other-length words (unlike the ARPANET, which sort of supported word lengths which were not a multiple of 8 or 16 - which was actually use to transfer binary data between 36-bit machines). > It *may* have been the IBM 360 that started the trend of Byte = > 8-bits Yup. And then the PDP-11 put the nail in that coffin (and in 1980, there were more PDP-11's, world-wide, than any other kind of computer). Noel

Microcode, which is a no-go for modern designs

by technoid6502＠gmail.com

What defines a 'modern processor'. The term is pretty slippery. The Crusoe used microcode to emulate x86 and could therefore emulate any processor architecture Transmeta wanted. Crusoe was a pioneer in the low power market, the processor dynamically clocked itself in very small steps depending on need. This is a familiar feature now but was pretty revolutionary for the time. Interestingly, Linux Torvalds was in on the design and was on the board of Transmeta. A fair number were sold to Sony for their VIAO series of notebooks. Does Crusoe qualify as a 'modern' processor? In my book yes, but I have a very old book.. :0 best, Jeff

uc04 + scsi2sd ?

by jacob.ritorto＠gmail.com

Hey all, Anyone know whether the Emulex UC04 works with the sd2scsi? I just bought a uc04 and it won't talk to any of my old scsi disks, seems to think there's supposed to be a "controller" in between :\ yuck. thx jake P.S. While I'm at it, anyone know how to get UC04 to talk to directly to plain scsi disks and tapes instead of these lunatic ESDI controller bridge things?

KD11-E/EA microcode flow diagrams

by jnc＠mercury.lcs.mit.edu

The copy of the KD11-EA engineering drawings (in the 11/34A Field Maintenance Print Set, MP-00190) on Bitsavers is missing most of the pages that hold the microcode flow diagrams. I have a set of the KD11-EA FMPS (MP-00192), which does have all the missing pages, which I can eventually scan. However, in the interim, the 11/34 Field Maintenance Print Set Vol. 2 (MP-00082) on Bitsavers has a complete set of microcode flow diagrams for the KD11-E (pp. 15-40 of the PDF), and they are almost identical to the KD11-EA diagrams. The only difference I can see (I compared page by page, to see if each page had the same microinstructions on it) is that on sheet 17; the last microinstruction for RTI/RTT has been moved from 002 -> 744. (The actual microinstruction contents seem to be the same.) I don't know whyo the changed address; I originally thought that perhaps they had to re-do the IR Decode ROMs when they added floating point, and they needed the original location to handle the start of the floating point microcode, but that doesn't seem to be the case.

PDP-11/45 RSTS/E boot problem

AFAIK, the only difference (in programming terms) between the -C and -D is that the -D has dropped the maintainance register. Although I cheerfully admit I haven't sat down with -C and -D manuals and done a bit-by-bit compare. I just did that (I used the "RK11-C Moving Head Disk Drive Controller Manual", DEC-11-HRKA-D, and the 1976 "Peripherals Handbook"), and found in the following: In the RKDS: bit 7 has changed the definition slightly ("Drive Ready" to "R/W/S Ready"), but seems to be basically the same. In the RKCS, bit 9 is "Read/Write All" in the -C, and unused in the -D; bit 12 is "Maint" in the -C, unused in the -D. In other words, a -D driver should work just fine with a -C, IMO. Noel

SPACE WAR for PDP-11 - link issues

by mattislind＠gmail.com

So after some intensive transcribing work I finally got all files into source files ready for assembling using PAL11-S. Assembling under PAL11-S rooted out a bunch of errors and then when side by side comparing the output listing with the PDF I found a bunch of more errors. The next step involved linking and during the first run a number of errors surfaced again. On the last run I only had two undefined: $ICO and $ICI. It makes sense since these two are part of the FPMP-11 package and used for number conversion. However adding the FPMP-11 object as an extra input in the link does not resolve these two undefined symbols. Does anyone have a clue on how to get a proper link with FPMP-11 for these two symbols? Here is the repo with PDF files, source PAL files, LST files and OBJ files as generated by PAL11-S: https://github.com/MattisLind/SPACEWAR /Mattis

Which DEC machine made use of th pre Flip-Chip board?

by jnc＠mercury.lcs.mit.edu

> From: Mattis Lind > I cannot figure out which early machine it comes from. They're called 'System Modules': http://gunkies.org/wiki/System_Module and they were used from the PDP-1 through (I think) the PDP-7; at least, this PDP-7 internals image: https://www.soemtron.org/images/jpgs/decimages/sn113robertjohnson85680004.j… seems to show System Modules at the top, and FLIP CHIPs at the bottom. (I'm pretty sure even the first PDP-8 - the 'straight 8' - uses only early FLIP CHIPs - transistorized ones.) The DEC brochure for it (P5141) is a little puzzling; it says (p. 2) that "INTEGRATED CIRCUITS are basic elements of the low cost, newly designed silicon FLIP CHIP modules used throughout PDP-7", but AFAIK, the first FLIP CHIPs (R-series, B-series, etc) were all transistors; the later M-series were the first ones to have ICs. Maybe this is some old meaning of "integrated circuits"? Noel

Microware OS-9 68K books

by ethan＠757.org

A friend and I went in on an Amiga 4000T haul last weekend, and with it were some nice hard binder and box Microware OS-9 68x00 books. I want to say there are two sets of two, and then some binders with photocopied style paperwork for BASIC. Is there any Microware fans that might want these? We were planning to put most of the Amiga software up on eBay to cut down the cost of the aquisition since it's mostly boring accounting/word processing stuff. There are no disks with these manuals, just looking to find them a new home. Can get more details if anyone is interested. -- : Ethan O'Toole

Pascal Microengine disks images available.

by jos.dreesen＠greenmail.ch

Finally got around to imaging the +/- 80 floppies that came with my ACI-90 Pascal Microengine system. Disks of general interest can be downloaded on ftp://ftp.dreesen.ch/WD9000/MicroEngine.zip These are mostly variants of the OS and a set of system selftests. Image SYSTEM/OS_F0_SingleDensity.IMD might be of particular interest as that is a single-density OS-disk, might be needed for those with very early systems. All others images are for double-density systems. Sorry for the lack of documentation, I don have anymore than this, and have yet to check the contents... As a sidenote, all BASF disks were unproblematic, unlike the ControlData and noname parts that were also in the mix. Jos

Bit 7 is "drive ready" in both. @*#$@*$%@&*!!!!! My silverfishionado nature screwed me! I didn't have an RK11-D manual in paper, so I relied on the "Peripherals Handbook" - and it's got an error! In both the 1975 and 1976 edition, the _diagram_ for the RKDS shows bit 7 as "R/W/S Ready", and bit 6 as "Access ready", but the _table_ shows bit 7 as "Drive Ready", and bit 6 as "R/W/S Ready"! OK, so let me ditch that, since it's self-contradictory, and thefore necessarily erroneous. I'll switch to the RK11-D User's Manual, EK-RK11D-OP-001. It gives bit 7 as "Drive Ready", and bit 6 as "R/W/S Ready". (The RK11-C manual gave bit 7 as "Drive Ready", and bit 6 as "Access Ready".) > Bit 6 has a different name in the two descriptions but the meaning > appears to be the same. Yup. Thanks for catching that for me! Noel

PDP-11/45 RSTS/E boot problem

by fritzm＠fritzm.org

Hi all, Some here may know I?ve been working on an 11/45 restoration off and on for some time now. My ?45 currently has floating point, KT11-C mem mgmt, 124 kword MS11-L, and an RK11-C with one restored RK05 drive. Last week I decided to see if I could bring up RSTS/E on the machine. I managed to sysgen a minimal V06C system that can run off a single RK05 pack under simh, but when I transfer that image to the real hardware using pdp11gui it does not seem to completely/successfully boot. The ?Option:? boot loader comes up and sub-commands there seem to be working (in particular, the ?HARDWARE? sub command shows correctly detected hardware and options). When booting RSTS/E, after supplying date and time, the idle pattern starts on the front panel (but just the bottom part, on the data lights). When console is in display register mode, it shows an increasing count. Console input is echo?d, but the INIT banner and subsequent prompts are never printed and the read light on the RK05 flickers continuously as if the system is trying to read the same sector over and over. Figured I?d ping here in case this is a known failure mode to folks more familiar with RSTS/E? Also posted over on the vcfed DEC forum. FWIW, the machine is passing all MAINDEC CPU, MMU, FP, KW11, and RK11 diagnostics. Cheers, ?-FritzM.

OCR old software listing

by ldkraemer＠gmail.com

I used the libtiff-tools (Debian 8.x - 32 Bit) to extract all 61 .TIF's >from the Multipage .tif file. While the .tif's look descent, and RasterVect shows the .tif properties to be Group 4 Fax (1bpp) with 5100 x 6600 pixels - 300 DPI, I can't get tesseract 3.x, TextBridge Classic 2.0, or Irfanview with KADMOS Plugin to OCR any of the .tif files, with descent results. I'd expect an OCR of 85 to 90 % correct conversion to ASCII text. Typically, one of the three above Software packages will do a descent job of OCRing .tif's of such scans. (Most PDF's end up at 72 x 72 DPI, and converting them to 300 DPI, allows them to be properly OCR'd.) If anyone else has had better luck, I'd like to know what your process is. Thanks. Larry

Apollo 8 Mission Control printers, or not?

by steven＠malikoff.com

Being the 50th anniversary of the flight of Apollo 8, I was watching a newly-uploaded informational film of the mission on Youtube: https://youtu.be/83cGclY9OZk?t=1092 At 18:02 and 18:13 there are what appeasr to be small blue/green tabletop printers on trolleys positioned next to the consoles. They don't have an I/O Selectric form factor but are more like a teletype, or something else entirely, in a sound-deadening box. There's no platen knob visible and it doesn't look to be fanfold paper (I think) so I'm just curious as to any idea what they are? Steve.

RSTS source tape

by iamvirtual＠gmail.com

Does anyone know the OFFICIAL status of RSTS/E source? I am aware of the Mentec license, but it appears to only grant a license to the binary distribution. I believe I have source tapes to RSTS/E version 5 & 6 that I would like to release copies, but I cannot until I can get official permission. I acquired the tapes from a person who did some development on early PDP-11's. I am checking my binary versions of the RSTS tapes and if they are ok, I can release RSTS/E V5B and RSTS/E V6B. --barrym

Osborne-1 with prototype-based motherboard

by vintagecomputer＠bettercomputing.net

Am just posting this as I am hoping someone out there knows someone who was involved with Osborne back in the day to find out more this Osborne 1 motherboard I found in a low serial O1 I picked up for $100. I reached out to Lee Felsenstein on it and he suggested it was related to the boards produced for the 10 prototypes Osborne built, or a derivative of them. He couldn't say for sure how it ended up in mine. But I was hoping if anyone knows any Osborne experts that might help me on this - it is not currently working and I'm hoping to find schematics, etc to get it going again. Obviously with the radical differences in layout, the schematics for the production motherboard isn't terribly helpful. I've posted a blog about it here with a picture of the board for those curious: http://bradhodge.ca/blog/?p=1186 Brad

OCR old software listing.

by mattislind＠gmail.com

Finally I got hold of the sources for the PDP-11 SPACE WAR that was submitted to DECUS by Bill Seiler. The format is scans of the PAL-11S listing output. It is easy to crop the image to only contain actual source. Then running OCR on it. Tried a few online versions and tesseract. The problem is that the paper that the listing is printed on has lines. Very black lines. It makes the OCR go completely crazy. Source lines without black lines OCR ok. The others do not. The files need massive amount of manual intervention. Does anyone have an idea how to process files like this? A good way to remove the black lines? There are only 19 source files with three or four pages each so I don't think it makes sense to try to train tesseract to do it (training tesseract seems to be a huge undertaking). https://i.imgur.com/dvY973s.png /Mattis

WTD: 9 track open reel for PDP-11

by w2hx＠w2hx.com

Hi friends, I've been building up a nice little PDP-11/23+ with cabinets, RL02's etc. To really round things off, I'm looking for a open reel-to-reel style 9-track tape drive to add to the system (don't ask why, punishment must be somewhere in my nature). Not interested in the autoloading/drawer type drives. There are some fujitsu drives on ebay at the moment, but shipping from CA to NY is both costly and risky. Does anyone have a (preferably working) 9-track drive that can be used with a PDP-11 (like a pertec interface) for sale? Willing to drive anywhere from Philly to Boston for one. Hopefully one in good shape. Thanks 73 Eugene W2HX

Which DEC machine made use of th pre Flip-Chip board?

by jnc＠mercury.lcs.mit.edu

> From: Allison > IC as in digital logic were in production in the early 60s Yes, but if you look at the picture/manual (I found a "Module location for I/O" chart on pg. 335 of the PDP-7 Maint Manual - alas, not the whole machine, just the FLIP CHIP part), the PDP-7 is all B-series and R-series FLIP CHIPs, which are all discrete transistors. AFAIK, the first ICs (in the modern sense) on FLIP CHIPS were on M-series. Noel

SCSI for HP 9000/380

by dennis.grevenstein＠gmail.com

Hi, I do remember that when installing HP-UX 9 and earlier, you could not mix and match SCSI and HP-IB. If you boot from HP-IB you can install on HP-IB, if you boot from SCSI, you can install on a SCSI disk. That may be a limitation in the installer. Once you have everything installed, you can use any device. I am very sure that this was the case with the 800s. I am not quite sure about the 300 series. I once owned a 380 and it worked well with SCSI disks and the onboard SCSI port. regards, Dennis

I have one of these, but the system has HP-IB disk and tape. I'd like to use a SCSI tape to install on it. On the CPU card, there is what looks like a 50-pin connector. Does that need active electronics to work like the second HP-IB bulkhead that currently occupies the slot? Also does anyone have digital manuals for this particular model? Regards, Kevin

NFS & Kerberos woes...

by cctalk＠gtaylor.tnetconsulting.net

Do any fellow cctalk / cctech subscribers have any experience with NFS, particularly in combination with Kerberos authentication? I'm messing with something that is making me think that Kerberos authentication (sec=krb5{,i,p}) usurps no_root_squash. Meaning that root can't access files owned by other users with go-rwx. Almost as if no_root_squash wasn't configured on the export. Does anyone have a spare bone that they would be willing to throw my way? -- Grant. . . . unix || die -- Grant. . . . unix || die

I believe that root should have access as the system's keytab has host/$FQDN and nfs/$FQDN principals. Root also has a ticket granting ticket, krbtgt/$REALM. At least I think that means that root has vlaid Kerberos tickets. > The no_root_squash option is no longer relevant when Kerberos > authentication is used, as you surmise.

Newbie Punch Tape Questions

by info＠cvmakerspace.ca

Ok - not so much of a newbie - fed punch tape into a reader for a PDP8 when I attended tech school back when the earth was cooling .... I have my hands on a PDP8a and a Remex reader. They both seem to function OK with basic tests. I would like to try to read a Mylar punch tape to see if there is anything interesting on it - as well as a couple of paper tapes. My end run would be to show something useful running on the PDP8a - and loaded with the punch tape. The Mylar reel would have been the programming for a CNC machine. I suspect the first part of the reel may be some boot loader or init routine. So, my thought is this - connect the Remex unit to a Pi or Arduino to capture the data and have a look at it or, load the tape directly into the PDP8 and see what happens? Then, examine the PDP8 memory locations. So, the issue is that I have not researched the proper way to get the tape and PDP8 initialized and reading into the PDP8. I am not 100% sure the Remex unit is working, other than it spins the reels. Any suggestions?? Love the forum by the way - I wish I had a machine that would slow the clock on the wall down to give me more time to play. I guess they call that retirement .....

Another weird paper tape

Speaking of paper tape...

by jfehlinger＠comcast.net

Does anybody here recognize the manufacturer of this gear, presumably some kind of punched paper tape equipment? Second to the last image at: http://www.tapeheads.net/showthread.php?t=15284&highlight=movies&page=10 I recently had the chance to play with a Blu-Ray transfer of the old gothic sci-fi TV show _The Outer Limits_ (the original 1963-64 series), and some of the 50s magnetic tape equipment used as recurring props can be identified -- e.g., an Ampex FR200 data recorder, Magnecord and Roberts audio tape recorders, and even a pair of old Univac Uniservo I tape drives in one episode. But that twin paper-tape device (if that's what it is), which occurs in the background of a number of first-season episodes, remains a mystery. The lower reels (if there are any) seem to be out of sight in the lower part of the cabinet in all shots of the device, and there seems to be a continuous loop of paper tape threaded around the tape guides and back up to the upper reel (which is actually spinning in at least one episode). Anybody know what this might be?

flashx20 - Floppy and screen for the Epson HX-20

by norbert_kehrer＠yahoo.de

Hi, the Epson HX-20 handheld computer offered an interesting way to connect it with peripheral devices. The serial port at the back of the computer can talk to external hardware using an Epson-specific protocol for data exchange. As this protocol is quite well documented, I wrote a little program called "flashx20" (for FLoppy And Screen for the HX-20), which allows to connect a normal Windows PC or notebook computer to the HX-20, where the PC interprets the Epson serial protocol and simulates an external display controller and four external floppy disk drives (like e.g. the Epson TF-20). With that, you get a big screen (the PC monitor) and disk space for programs and data on the PC's hard disk, which can then also be used for data and program exchange. You can read more about it and download the program from my website at http://members.aon.at/nkehrer/ Norbert

Unknown paper tape format

by kylevowen＠gmail.com

I found a spool of mylar tape dated 23 March 1972, with "EARS" on it; best I can tell, this was for the Experimental Array Radar System. Image can be found here: https://drive.google.com/open?id=11VKKklor1QDyWCz0b3zVNj_I_vmt4oN4 Anyone have any clue as to the format? Here's the beginning of the tape: 0000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 * 0000060 00 00 00 00 00 00 00 00 00 00 00 40 40 40 08 e5 0000070 43 c1 40 5b 43 c1 40 dc 43 c1 40 5d 43 c1 40 5e 0000080 43 c1 40 df 43 c1 40 e0 43 c1 40 61 43 c1 40 62 0000090 43 c1 40 e3 43 c1 40 64 43 c1 40 f1 c2 c1 40 f2 00000a0 c2 c1 40 73 c2 c1 40 f4 c2 c1 40 75 c2 c1 40 f7 00000b0 c2 c1 40 45 43 c1 40 46 43 c1 40 c7 43 c1 40 c8 00000c0 43 c1 40 49 43 c1 40 4a 43 c1 40 4c 43 c1 40 cb 00000d0 43 c1 40 d5 43 c1 40 d6 43 c1 40 4a 40 c1 40 cd 00000e0 40 c1 40 cb 40 c1 40 7f e0 c1 40 f2 45 c2 40 57 00000f0 43 c1 40 58 43 c1 40 d9 43 c1 40 da 43 c1 40 6e and the end: 0006400 45 c2 40 57 4c c1 40 5e 4c c1 40 f4 cb c1 40 e5 0006410 4c c1 40 fb cb c1 40 ec 4c c1 40 e0 7f 7f 40 40 0006420 40 c7 40 73 4c c1 40 7a 4c c1 40 c7 40 40 40 da 0006430 c8 c2 40 ef 57 c1 40 c1 cd c1 40 46 d0 d0 40 79 0006440 cd c1 40 d5 57 c1 40 4f cd c1 40 5d cd c1 40 c2 0006450 4c c1 40 6b cd c1 40 c8 cd c1 40 58 cb c1 40 df 0006460 cb c1 40 e6 cb c1 40 f2 cd c1 40 46 40 40 40 cd 0006470 40 40 40 4c 40 40 40 d5 d6 c1 40 d5 61 c1 40 40 0006480 61 c1 40 fb d3 c2 40 c7 ce c1 40 7f 57 c1 40 c2 0006490 cb c1 40 49 40 40 40 e3 d6 c1 40 f2 d6 c1 40 58 00064a0 57 c2 40 76 d9 c2 40 40 40 40 08 07 80 80 80 00 00064b0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 * 0006600 00 00 00 00 00 00 Would love to know what computer system this was running on.

Origin of 'Straight 8' name

by jnc＠mercury.lcs.mit.edu

> From: Al Kossow > "Straight-8" seems to be a fairly modern name coming from collectors My _guess_ is that that probably happened because there is no formal 'model' for that first one (unlike the first -11, which got re-named the -11/20 BITD), and people recently picked that to disambiguate them from all the other -8's. But what I _don't_ know is _why_ that particular name? I was hoping some -8 collector knew... Noel
