FS: Tek scope, HP LA, and Electronic components!

by mechanic_2＠charter.net

Hello all, I have probably developed cancer. I can't get in for treatment. I have enough lumps in my body that it probably wouldn't make a difference. So more than likely I am dying. I am asking for everyone's help. I am selling off all of my processions and simplifying my life before I die. I don't want to see this stuff end up in the landfill. Please help out a dying old man? I have a Tektronix 465B Scope with four probes for sale. A HP 16700A LA with 5 16555D LA cards and all of the cables. There is a 16701B Expansion box and the interconnect cable. There is an external SCSI drive box with a CD rom and a ST318417N drive in it. There are a bunch of micro probes for the LA. A monitor, keyboard, mouse, manuals, and CDs. I also have a very large collection of electronic components in over 40 storage cabinets. There are also a lot of books on electronics. I am asking $250 plus the shipping on the scope. This shipping won't be cheap. $500 plus shipping for the LA. Again shipping will be very expensive. It will take five boxes to ship the LA. I will deliver the scope and/or LA to any where in the lower 48 for the cost of shipping. $500 for the components, cabinets, and books. Shipping is not possible. So it it have to be local pick up. Bring a truck and trailer. PP F&F, Cashiers Check, or Postal Money Order. Please contact me off list. GOD Bless and Thanks, rich! Happy Thanksgiving!

Hi Chris, There's a few options in this regard, in increasing degrees of "realness" (and cost!) depending on how you define it. 1) The PiDP-8 by Oscar Vermeulen - Raspberry Pi based 8/i replica running SIMH in a miniaturised case. https://obsolescence.wixsite.com/obsolescence/pidp-8 2) The SBC6120 - Originally by Spare Time Gizmos, but now re-released by the RetroBrew Computers community. This is a 6120 based PDP-8/e replica, with optional front panel. (the panel doesn't appear to be made "officially" anymore, as the design files are missing, but a Russian company appears to have copied it. (I have the Russian version but have yet to assemble it.) https://www.retrobrewcomputers.org/doku.php?id=boards:sbc:sbc6120-rbc-editi… http://www.sparetimegizmos.com/Hardware/SBC6120-2.htm https://chipkin.ru/product/pechatnye-platy-dec-pdp-8-e/ 3) The LD12 / LD20 by Franklin Prosser and David E. Winkel - This is a TTL based clone of a PDP-8/i, originally devised as part of an exercise in the book "The Art of Digital Design An Introduction to Top Down Design" in the early 80s. A few people on vcfed.org have built their own based on these designs, and daver2 has made a run of PCBs (wirewrapped!) http://www.vcfed.org/forum/showthread.php?74125 4) Vince Slyngstad of so-much-stuff.com has scanned many PDP-8 boards and re-created them in Eagle CAD software. I know he's been working on re-creating the 8/e CPU recently but AFAIK it's not finished yet. There are however many OMNIBUS peripheral cards, and a board that combines 32KW of battery backed RAM with a boot ROM. Roland Huisman has also re-created the RX8E floppy controller, and has made an RX02 emulator to go with it, so if you lack an RX01/2 drive you can still have something to boot off. Kyle Owen has also created a neat bit of software that allows you to use a spare serial port and a *NIX system to simulate an RK05. So with all this, it should in theory be possible to build your own 8/e class system soon enough if you can find all the parts for it. http://so-much-stuff.com/pdp8/cad/boards.php https://github.com/Roland-Huisman https://github.com/drovak/os8diskserver Regards, -Tom mosst at sdf.org SDF Public Access UNIX System - https://sdf.org

Osborne 1 keyboard repair - success!

by ccth6600＠gmail.com

I have managed to completely disassemble the bad Osborne 1 keyboard - remove all key mechanisms (body, plunger, main spring and actuator spring), remove the 3 layer membrane from the aluminium backing board and separate all three membrane layers (bottom, spacer and top) - all without damaging or losing any bits. I then carefully cleaned off all adhesive and other sticky gunk from all layers using various solvents including water, isopropyl alcohol and white spirit. The silver tracks remained undamaged as confirmed with a multimeter. I then carefully reassembled the 3 layers, inserted and super-glued the keyboard mechanisms in batches, testing after each batch. I did not use any glue to reattach the 3 membrane layers so they are held together only by the keyboard mechanisms with their prongs protruding through the layers into the aluminium backing plate to which the prongs are super-glued. I sealed the edges around the membrane using Kapton tape to provide protection from dust etc. The tape also attaches the membrane edges to the aluminium backing plate. All keys except the "Alpha Lock" key work perfectly. It appears that I have damaged the address line 7 on the bottom membrane. I can live without "Alpha Lock" so I did not pull everything apart again to fix this un-important key. The conclusion is that membrane keyboards can be fixed if your life depends on it. It is absolutely uneconomic though. I worked about 30 - 40 hours on the keyboard alone. Working Osborne 1s sell for between US$100 and US$300 on Ebay. Regards Tom Hunter

Hey all -- Got a nice 8KW omnibus core memory board here, designated the "E1" from Keronix, that almost works except that bit 1 is off in the weeds somewhere. Not a lot of information out there on Keronix hardware, anyone have any docs? The board came with a sheet describing the addressing configuration, but that's it. Thanks as always, Josh

Crypto Ancienne: TLS for the Internet of Old Things

by spectre＠floodgap.com

If you have an older pre-C99 system, I've backported a TLS 1.2 library to gcc versions as early as 2.5 as long as it has 64-bit ints (long long, usually) and stdarg.h. https://github.com/classilla/cryanc As a test, with a suitably agreeable (or confusable) browser, here are various period browsers visiting modern HTTPS sites through carl, the included demonstration application which can also act as a TLS proxy. The proxy is running on the same machine, no tricks! OmniWeb, at least two flavours of NCSA Mosaic and MacLynx are all demonstrated. https://oldvcr.blogspot.com/2020/11/fun-with-crypto-ancienne-tls-for.html -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Good software lets me sleep. -- Michael W.

evil thing to ask but I need keystroke logger

by boris＠summitclinic.com

If it's a windoze system, modified a bare-bones keylogger about 10 years ago which records all keystrokes (can get time of key_press, key_release) and also monitors all mouse clicks as well as title of window clicked on. Can also record every mouse event which takes up a LOT of disk space. Just hooks keyboard and mouse events and works even on hospital systems which are fairly locked down. Written in VB6 and also wrote a program to either look at keyboard/mouse events over time or to dump text typed in. Has saved lots of work for me as windoze has a bad habit of crashing when I'm 20 minutes into writing a note and can get all keystrokes that were saved to disk during this time. Initially written to find out how much time I spent IFOK. Also has a stealth mode where keylogger window hidden and can be brought up with a key sequence and then need a password to stop it. Not very stealthy as can be easily terminated through ProcessExplorer. Could always use Wireshark to capture all packets exchanged while they're on computer. >I have kids that after corona are in lockdown, so they are on >computers all the time. >Supposed to be doing schoolwork, but no, feedback from the school is negative. > >Can I trap some traffic from these PC's and what software would you recommend? > >Randy

Seagate Elite "reverse surging" noise

by jules.richardson99＠gmail.com

I picked up a couple of 9GB Seagate Elite SCSI disks the other day (model 410800N, 1995-vintage but 5.25" FH units). Both drives spin up, both pass r/w tests successfully. On one unit, the spindle motor sound is constant. On the other, however, it makes a sound that I can best describe as "reverse surging", where every 5 seconds or thereabouts there's a very brief lowering in tone before the "normal" sound resumes. Anyone familiar with the Elite range know if "some of them just do that", or if it's likely to be some form of fault (which may only get worse)? I've never encountered a disk which does this before; my ear's not detecting any kind of speed increase prior to the decrease (and I don't know if that's what's really going on or not), but that's what my brain wants to think is happening. However, if the speed really was fluctuating to the point that I could hear it then I'm surprised that I'm not getting read/write problems. cheers Jules

TU58 dumps. Mostly VAX 11/750 AND 11/730 diags and console tapes.

by mattislind＠gmail.com

I dumped almost 50 TU58 tapes. They were given to me by an ex DEC FS engineer. Most of them are various 11/750 diagnostics. The tapes or not the official DEC TU58 tapes but home brewed tapes used in FS so there might not be an exact match to existing lists of official tapes. But they might be useful anyhow. I have seen diags for CI 750, DW750, RH750, DT07, Various Ethernet, UDA50, TK50, DZ32, DMF32, DH11 and some more standard 11/750 MIC, DPM tests and instruction tests. Then there were some 11/730 tapes. Console and two diag tapes. I collected everything in a google-drive-folder https://drive.google.com/drive/folders/1CkcXVJS9aJDwD4ihdj27QYcgkm7gEdrQ?us… This folder also contains some older dumps I have done. Both DECtape and DECtape II. All dumps are aggregated into a document trying to give a hint on what the dump contains. Beware that some dumps failed to read correctly and are just partial. But it should hopefully be clear from the file size. https://docs.google.com/document/d/1vD8erJM-HitSd4kRXt6_Rzl403HDoprr08EY69u… /Mattis

Looking for Console MUX cable for HP E45

by rp＠servium.ch

I recently acquired a HP 9000 E45. Unfortunately, it came without the console MUX panel and cable. I was lucky to find an ADP II (5062-3054) in my "pile of useful stuff", but sadly, the 78pin to DB9 cable is missing. The part number of the cable is 5060-3074 though there might be others that work (5062-3074 is mentioned a few times in the HP forums, but not in the manual so I'm not 100% certain it's the right cable). Does anyone have a spare cable or an ADP or DDP with the cable they would let go for a reasonable price? Or have one and could tell me which 9 out of those 78 pins go where on the DB9 connector? thanks Rico

Microvax 3100 VMS 7.3 password reset

by athornton＠gmail.com

I for one was thrilled to see that there will be x86_64 hobbyist licenses for VMS. I have an emulated VAX on a Raspberry Pi (I don?t know if my 11/730 works, but I doubt it?it?s nowhere near a 220V power supply and it?s not been much of a priority, and I have a VAXStation 3100 that doesn?t pass POST even with a freshly-burned ROM) running OpenVMS 7.3, and a real AlphaServer 800 running 8.4. I mean obviously the NEXT thing to do is start bugging VSI for ARM support?given that the OS runs on VAX, Alpha, Itanic, and x86_64, how much really crucial and hard-to-port assembly can be left in it??and given the way datacenters are trending, it might not even be a commercially stupid move. I want to run VMS on my phone (or my next Mac). Doesn?t everyone? Adam

Next project: 11/24. Does it need memory?

by jnc＠mercury.lcs.mit.edu

> From: Jay Jaeger >> 2--M7134 KT24 Memory map > M7891 UNIBUS Memory (256K, I think, presumably addressed for 0). If that's all the memory you have, the KT24 isn't really doing anything (well, monitoring power; holding boot PROM's; etc). Is your MS11-L configured to be EUB memory, then? If no KT24 is plugged in, the CPU detects that there isn't one there, and permanently, statically maps the UNIBUS straight across to the bottom 256KB of EUB space. (Presumably a low-cost option for the /24.) Although the 'straight across' mapping only applies to UNIBUS->EUB cycles, not EUB->UNIBUS cycles, such as those from the CPU; but the TM says [pg 2-31 in the 003 version] that if E124-S6 is OFF, "the lower 18 bits of every address go to the UNIBUS", which implies that when OFF, UNIBUS memory appears at 0 in the CPU's address space. So it should work as UNIBUS memory, with E124-S6 OFF; it would be interesting to verify that. The TM also says (pg. 2-40) "systems with UNIBUS memory ... require changes to be made to the mapping jumpers [on the KT24]". > Let me know if you want me to go thru the process of > .. > 2) Pull the boards and document What kind of box is your -11/24 in, a BA11-A, or BA11-L? If the latter, I'd be really grateful for some closeups of the interior, so I can put mine back together, and do some of these experiments. (Yes, yes, I know I should have taken pictures before I took it apart; I was just starting, and was going by how we used to do things, back before there were digital cameras.) I could probably work it out by staring hard, and thinking harder, along with the prints, but photos would be a lot easier! :-) If it's a BA11-A, I'm still trying to get an image of the special power adapter used to turn the bus bar of the BA11-A into the 6/15 pin Mate-N-Lok connectors used by the -11/24 backplane.
