VM/370 notes

by Steve Lewis

Hey all, I was trying to track down some kind of image/photo of "what IBM VM/370 looks like" (the operating system) I tried looking also in the IBM manuals - I'm just not finding much. Some kind of image of what maybe a remote login looked like, a task process list, or maybe basic file/folder management commands, or how an editor or programming worked on that system. There is a bit of media with a VM/370 emulator, but I wasn't sure how accurately representative it was of a kind of "look and feel" of that OS. What I'd need is maybe photographs of teletype printouts? This was still early 1970s. Which is understandable not much of that was probably kept around. Thanks, just digging around - like wasn't sure if VM/370 was still six-character filename limited like earlier 60s era OS's, or whatever characteristics it had in operating it. -Steve

PDP-8 software for the DEC MPS (MIcroProcessor System)?

by Robert Armstrong

Short version - I'm looking for copies of the PDP-8 software for the DEC MPS, MIcroProcessor System. Longer form, since it wasn't very well known - DEC made an 8008 (yes, 8008, not 8080) microprocessor based system on a set of three quad sized modules, plus a really nifty looking lights and switches front panel. It's not clear what DEC expected customers to do with it; I guess use it to build an embedded control system for things that were too simple for a PDP-8 or -11. In any case, DEC made a whole software development toolchain for the MPS and 8008 using a PDP-8 as a host computer. There was a cross assembler (aka MPA), a downloader (aka MPL), a specialized text editor (yes, MPE), a debugger (you guessed it - called MPD), a EPROM programmer, and several other miscellaneous tools. They were all distributed on paper tape and I believe they were intended to run on a basic 8/E and Teletype, without mass storage and without OS/8. If anybody has these, I'd love to get copies of the tape images. Thanks, Bob

Datapoint 2200 emulator and CTOS

by Steve Lewis

I just came across this today, it looks like work that came about around January 2024 by Mattis Land. Mattis, not sure if you're active here, but this is really great work! The emulator code is here: https://github.com/MattisLind/DP2200/ An Unlisted demo of the emulator in action is here (running some CTOS software): https://www.youtube.com/watch?v=XfsMBhP13ww Might this CTOS be the only operating system fit on an audio cassette tape? -Steve

Hi Ali, I just replied to you through the vcfed forum. My posting is being moderated (likely because I'm an infrequent poster) but I am interested in your HP 2563C printer. Stan

Identifying This Component from VT100 Monitor Board

by Robert Jarratt

I asked this before a few years ago but didn't come to a firm conclusion. The two parts are shown in this picture: https://rjarratt.wordpress.com/wp-content/uploads/2023/12/img_20231221_1123… They are from a VT100 Monitor board. There is no schematic for my version of the board, but a related schematic is on p58 of this schematic: https://bitsavers.org/pdf/dec/terminal/vt100/MP00633_VT100_Schematic_Feb82.…. They are labelled Q414 and CR406, but the Feb 82 revision uses a different board and those two parts are in TO-220 packages rather than TO-3 as here.. I have removed both of them and tested them with a DMM. Neither of them measure as two diodes, they do not measure open circuit in any direction, so either they are both faulty or they are not transistors (unlikely). I have found a spec for a 2SB411 at https://alltransistors.com/transistor.php?transistor=10279. This seems to be a germanium transistor. When I last asked about this I had a conversation with Tony Duell, who was very sceptical that these could be germanium transistors, so naturally I am very doubtful that they are 2SB411 transistors. However, in the schematic Q414 is shown as NPN, the 2SB411 is PNP and this seems to match the way the part is connected on my board (Collector to HORIZ GND). I am working on a reverse engineered schematic. Can anyone tell me what these components are so I can find a datasheet for them? Better still a suggested replacement would be really helpful, especially if they are 2SB411s because they seem to be hard to find. Thanks Rob

Random PCI/AGP cards, WinTV, ES1371 sound etc (UK)

by David Brownlee

I find my collection of random old cards overflowing and I have picked out six random PCI/AGP cards on the offchance anyone is interested - Hauppauge PCI WinTV - ES1371 AudioPIC (x 2) - PCI Audio/modem card - ATI AGP Rage Pro 109-73100-02 - ATI Radeon 9550 128M AGP Images at https://postimg.cc/gallery/Y7PRkCG Are the cards of any interest to people? (for the price of postage or collection from London, UK :) I may also have a phenom 9550 with its motherboard, some and a selection of PCI plus IDE/SATA network cards - let me know if I should go digging...

Robert Tinney the man who created many of the early Byte Covers passed away.

by Christian Liendo

https://tinney.net/in-memoriam Robert Frank Tinney, of Washington, Louisiana, passed away peacefully at River Oaks Nursing & Rehabilitation Center on February 1st, 2026, at the age of 78. Born in 1947 in Penn Yan, New York, Robert moved at a young age with his parents, Ellis and Ruby, and his younger brother, Bill, to Baton Rouge, Louisiana. From Istrouma High School, Robert took with him a diploma, life-long friendships and a focus on artistic expression to Louisiana Tech University to study illustration and graphic design in commercial art. After graduating, and after a tour of service during the Vietnam War, Robert began a career that would see his artwork don the covers and pages of some of the most well-known computing publications in the world, most notably BYTE Magazine. Due to his signature artistic style, the name Robert Tinney soon became synonymous with the rapidly-growing world of computing technology, and remains so to this day. A deeply caring husband and family man, Robert is survived by his devoted wife of 48 years, Susan, three children, nine grandchildren and one great-grandchild. Married in 1978, Robert and Susan lived and worked in Baton Rouge until 1987, when they moved to Washington, Louisiana, where they would restore an historic landmark home, the Crawford House. For over four decades, Robert and Susan served and nurtured their beloved community with open arms, and were rewarded with priceless family memories and an exuberance of rich, cherished friendships. Robert’s philosophical intellect, refreshing humor and profoundly sympathetic nature will be sorely missed by his loving family and a wealth of loyal friends and admirers. A celebration of Robert’s life will be held in May, 2026. For more information, RSVP to illustrations(a)tinney.net.
