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)? Easier access to individual signals for debugging? Needless to say, if people who want to build one of these also have to do this, I wouldn't exactly call it 'painless'! :-) Noel

Interlan 2010 (QBUS) manual

by jnc＠mercury.lcs.mit.edu

Does anyone have an Interlan NI2010 (the QBUS version of their Ethernet interface) manual? Bitsavers has the NI1010 (UNIBUS), and I have a driver for the 2010, and between them I can probably figure out the 2010, but the 'real thing' would be superior. Noel
