There's a new adapter board for the BlinkenBone system. Now you can painlessly plug a physical 11/70 panel to the extended SimH running on a BeagleBone. See http://www.retrocmp.com/projects/blinkenbone/physical-pdp-11-70-panels/288-… Entry to far-too-many web pages here: http://retrocmp.com/projects/blinkenbone All in all there are now at least 3 different (but compatible) ways to get a blinking 11/70 with SimH. - Connect a real 11/70 panel http://retrocmp.com/projects/blinkenbone/physical-pdp-11-70-panels - Run the virtual Java panel http://retrocmp.com/projects/blinkenbone/simulated-panels/243-blinkenbone-p… Download &run from github https://github.com/j-hoppe/BlinkenBone/releases - get Oscars Vermeulens PiDP11 http://obsolescence.wixsite.com/obsolescence/pidp-11 Is that enough '70 now?

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.

Obscure IBM trivia T-shirt

https://www.zazzle.co.uk/ikf4084i_c_t_shirt-235922162936523884 In the 1970s I got a catalog from a T-shirt company named "Outer products" and this one was in it.

Looking for SGI Onyx system and/or parts

by kyle000＠gmail.com

Does anyone have any SGI Onyx parts? Any parts. I am trying to resurrect a deskside r10k onyx, and will need parts - right now I am more focused on power and VCAM parts, but again, I am interested in all parts. And if you have a system, I would be interested as well. This is the original onyx, not the onyx2. I have an issue that is power or vcam related. thanks.

> 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. 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

PDP-11 Memory

> 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). I certainly have a QBUS chassis right next to my workstation here that i) has a bunch of empty slots, and ii) works fine, as long as there are no empty slots between the CPU and the devices. Also, IIRC he said it works with 3 cards plugged in, but not 4; how can plugging a card _in_ cause grant problems? > For most microspheres backplanes the first three slots are different > than remaining.

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.

IBM in TX

by jnc＠mercury.lcs.mit.edu

> From: Fritz Mueller > They'd nicely compliment or house those new QSIC indicator panels > you've been working up, huh? :-) Complement. 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

Bogus "account hacked" message

by seefriek＠gmail.com

FWIW, I use a password manager (Keepass/Keepass2, tho there are other good ones). It's another step or two in my workflow, but let's me have a unique, very strong password for everything I log into. Greatly reduces the impact of password dump attacks.

IBM APL/PC unofficial patch for memory >512KB

by bear＠typewritten.org

IBM's APL/PC v1.0 crashes if you try to run it on a PC with more than 512 KB RAM. I learned today that there was a patch published to make it work on systems with 640 KB. Of course, I can't seem to find any trace of it. Anyone save a copy or know where it might be found today? ok bear. -- until further notice

RL02 packs FTGH in 01057

by wilson＠dbit.com

So I'm consolidating my storage and finding I have a lot of surplus stuff. For starters, I have a few too many RL02K-DCs (also a few RL01K-DCs and a couple of 12-sector RK05 packs): http://www.dbit.com/wilson/RL02K-DC.jpg Believed to be good/usable but of course I guarantee nothing. YMMV. YHMC. Located in Monson, MA, 01057, USA. I'll drive anywhere in southern New England to deliver some / a few / all of them, for free. Anything more complicated is OK, at your expense.

Microcode, which is a no-go for modern designs

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
