Re: [vcf-midatlantic] Does anyone know the substitute germanium transistor for a B1182

Good point, I’ll just recap the monitor board then and start from there. If the transistors seem bad, I’ll bring the board to either the SystemSource workshop at the end of this month or the VCF one at the beginning of March.

It’s a different package and I think in a lot of cases you can’t swap out germanium for silicon in older circuits so I’d prefer to stay with germanium.

by corey cohen 17 Jan '24

Hi, Working on my dead ADM3a video, I realized I may need some spare parts before I start working on it. I tried to find a cross-reference to B1182 transistor which is Q106 on the video board. This is a Germanium transistor in what seems to be a TO-66 case. Spent an hour Googling and can’t find a cross reference and no one seems to have them available in the correct Germanium. Thanks, Cheers, Corey

A 4004 Based Microcomputer the Comstar System 4

I'm not entirely happy that a thread that has drifted to Asimov's Laws of Robotics, has my name in it. I'll respond to the original points, on the original subject line. Those people interested in robotics, maybe can start a new thread subject? Those interested in Christian's Comstar might reply to his thread. I did not mean to hijack Christian's thread, just to embellish it, underscore his challenges in finding information and referencing the Compstar as various kinds of computer. Jeff acknowledges my point and adds modern context, other devices. Yeah, there's a long history about logical mechanisms as some kind of computing or analytical thing or even a kind-of person. If I'm not mistaken, Christian has/had in hand physically, at least the "compiler" Comstar product, maybe also the "controller" product? Not quite clear what he owns. I hope he puts it up on some kind of Web page or other editable Web-accessable thingy, that has stability and can be edited and refined. Too hard to do that in threaded discussions (this a case in point). It's not all nuts and bolts, the chips and a few words don't define the objects. I find this research, or curation, as much fun as restoration and repair. For those who have lost interest in those considerations and simply think "it's a computer, move on!"? Well, these things matter to some of us (oldies) who have seen a lot of change in the computing we have experienced. Those who look back decades and before their time, might get a richer experience by becoming aware of the expectations then, versus expectations at other times. As Christian describes, there's still discoveries to be made in vintage computing. Regards Herb Johnson Herbert R.

ReGIS files?
by Dave Shevett 14 Jan '24

14 Jan '24

I'm trying to locate a set of files that were distributed on DEC Pro 350's with graphics cards - mid 80's. They were ReGIS graphics files that had some pretty amazing artwork. I don't suppose anyone has a copy lying around, or knows where I can grab them? The art was super-nice, i'm considering a ReGIS exhibit at the next VCF. -d -- Dave Shevett shevett(a)pobox.com

Looking for help at March 2 Repair Workshop
by Brian Schmult 14 Jan '24

14 Jan '24

I am planning on attending the next InfoAge repair workshop on 2 March 2024 and hope to narrow the causes of video problems I'm having with a 1992 386 ISA-bus PC. The PC motherboard is compromised from previous battery leakage but was mostly working until recently. I have an apparently now dead original VGA card and a possibly flaky generic VGA card. I'm hoping to test the VGA cards in a known good similar PC and known good VGA cards in my box. Any assistance at the workshop, or other advice, would be greatly appreciated. Best regards, Brian Schmult

Fw: [Premium-Rx] HP-64000 System - FREE

Just forwarding. Just the messenger, don't shoot. Sent from Nine<http://www.9folders.com/> ________________________________ From: Michael Riley via Premium-Rx <premium-rx(a)mailman.qth.net> Sent: Saturday, January 13, 2024 11:07 AM To: premium-rx(a)mailman.qth.net Subject: [Premium-Rx] HP-64000 System - FREE Greetings. This posting is closely related to some old WJ receivers. But it is not a premium receiver. Sorry. I have the following available for FREE: A complete and working HP-64000 Development System. It was used to develop the embedded software in some WJ receivers and equipment. Model numbers I was able to extract are listed below. The HP-64000 System consists of the following: HP-64000 terminal (qty. 1). HP-7912 disk drive, 65.6 MBytes (qty. 2). (One disk drive includes an internal tape back-up unit.) HP-9144 tape back-up unit (qty. 1). HP-64224A '80186' Emulator Probe (in-circuit emulator). HP-64516A EPROM programming module (supports: 27512, 27513, and possibly others). A number of back-up tapes. Some cables. Misc. other related 'stuff'. Note: I do not have any manuals. An HP museum in Australia (and at least one other website) have scanned and posted many manuals related to this system. The system is quite large and heavy. (The manual states that one HP-7912 disk drive weighs 148 pounds. As a guess - the terminal weighs about 50 pounds.) I can provide dimensions, photos, detailed module numbers, etc. - on request. If you're within a "reasonable" distance of Annapolis, Maryland (USA), I'll even consider delivering it, help set it up, and a quick demo on using it. (Assuming I can get it loaded into my truck.) I compiled a list of equipment and acronyms from the disk (user) listings. I'm pretty sure the WJ8718 is complete. In other words all the embedded software is there. I believe at least one of the controllers in the WJ9195C is complete. It would appear that the WJ8628 is complete. Specifically which sub-models, I do not know. Many models and acronyms are unknown to me. If you look at the source files, you could possibly figure it out. Also available, FREE, is a Printronix P300 large format high speed line printer on rolling stand. It connects to the HP64000 terminal. It worked the last time I tested it. (It's RS-232, so any computer can use it; not just the HP64000.) Let me know if you want this system or have any questions.

replying and elaborating to Herb Johnson's postings re: 4004 Based Microcomputer
by Jeffrey Jonas 13 Jan '24

13 Jan '24

This touches upon several of my pet peeves, so please pardon the way my reply drones on and on and on until I start foaming at the mouth and falling over backwards ... Oh! https://youtu.be/DO7VkEFZ7B8 [Monty Python skit] Herb touches upon how our expectations of "computers" have evolved. To folks outside the engineering profession, "embedded processors", "industrial controllers" and other special-purpose machines don't look-and-feel like that's now accepted as a "computer". Yet the Arduino has made such embedded processing more accessible than ever to the hobbyist, experimenter, artist, etc. Perhaps that applies here: what were once called "computers" are now considered embedded processors, IoT (Internet of Things) or Internet appliances. I was about to say how cellphones are more of an appliance than a computer by the way most folks just download apps. They're not self-hosting, requiring a host system to compile the code. But then again, even I am using my home PC as an appliance. I rarely program or even customize it. I'm running the web browser, text editor, moving files, etc. Having salvaged lotsa vintage electronics, I've seen the insides of lotsa equipment. I've subscribed to Circuit Cellar from the beginning. They were an early advocate of single chip microcontrollers. These chips come to mind when thinking of embedded processors (in chronological order) 1) https://en.wikipedia.org/wiki/Intel_4004 1971: the Intel 4004. I encountered one deep inside a Calcomp DS12 hard drive controller. See page 55 http://www.bitsavers.org/magazines/Datamation/19710801.pdf [AND FOR THE RECORD: the 4004 was the first _commercially_available_ microprocessor. The military was first with the MP944 chip set for the US Navy's F-14 Tomcat fighter's CADC: completed June 1970. https://firstmicroprocessor.com/ https://www.computerhistory.org/siliconengine/microprocessor-integrates-cpu… https://en.wikipedia.org/wiki/F-14_CADC https://www.wired.com/story/secret-history-of-the-first-microprocessor-f-14/ ] 2) https://en.wikipedia.org/wiki/Intel_MCS-48 This family of single chip microcontrollers was released in 1976. The IBM PC used them as the keyboard controller (allowing a thin coiled cord and serial link instead of ribbon cable and parallel interface). 3) https://en.wikipedia.org/wiki/Zilog_Z8 1979: the Zilog Z8. Very popular with hobbyists for the piggyback ROM socket. Circuit Cellar / Micromint made many Z8 systems such as FORTH in ROM. http://cini.classiccmp.org/pdf/MicroMint/Micromint_Z8_Forth.pdf 4) https://en.wikipedia.org/wiki/PIC_microcontrollers 1976: General Instruments' PIC (Peripheral Interface Controller) evolved from ROM only to flash memory, so they're easily reprogrammed and re-purposed. PIC, like PDP, is a name to avoid saying "computer" or "microprocessor". 5) https://en.wikipedia.org/wiki/AVR_microcontrollers 1996: Atmel AVR series of single chip microcontrollers. Similar to the PIC, popularized by the Arduino. The Arduino ecosystem is no longer just for experimenters and hobbyists. It's now used for Industrial automation and machine controllers, replacing embedded processors such as the Z80 and STD bus. See: https://www.automationdirect.com/open-source/home What scares me is NOT the tool but how you use it. Just as everything looks like a nail if you have only a hammer, and screwdrivers have been abused as pry bars, wedges, paint-can-openers, etc. The Arduino is just a tool. My fear is the lack of disciplined programming, proper safety engineering practices and peer review of mission critical devices that risk injury or death. I remember the horror of the Therac-25. Do you? https://en.wikipedia.org/wiki/Therac-25 Even Google knows to throw me relevant ads: https://www.onlogic.com/ "Ideal for IoT, Edge and AI Inferencing applications" Just like the movie Westworld, what could possibly go wrong ... go wrong ... go wrong https://en.wikipedia.org/wiki/Westworld_(film) https://en.wikipedia.org/wiki/Westworld_(TV_series) That's what happens when robots/androids violate Isaac Asimov's "Three Laws of Robotics" 1) A robot may not injure a human being or, through inaction, allow a human being to come to harm. 2) A robot must obey orders given it by human beings except where such orders would conflict with the First Law. 3) A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. and that's the way it is. -- jeff jonas

A 4004 Based Microcomputer the Comstar System 4

This is good work, but I am reluctant to consider many early uses of microprocessors as "computers" without further explanation. The simple reasons are 1) many early implementations were for use as controllers, or logic-replacements; 2) the idea of a "computer" has changed many times from the era before microprocessor and during microprocessor developments in the early-to-mid 1970's. 3) The world of computing technology in the 2020's is so different from my world of them in the 1970's, calling something particularly early a computer obscures those changes. Fewer US people today are employed in US manufacturing or production. So "industrial" doesn't have a lot of personal context today. Apparently that Comstar 4, and certainly early use of the Intel 4004, are examples of industrialm controls. From Christian's documents, the Compstar System 4 was a replacement for ladder-logic or PLC (programmed logic) controllers for industrial control. The PLC program was cross-compiled on some mainframe or minicomputer running a FORTRAN program. That was a very common means of microprocessor programming in the early-mid 1970's. Gary Kildall (later of CP/M, Digital Research) produced FORTRAN assemblers and PL/M compilers for Intel's 8008 and 8080, for development of industrial applications. It's good to see this Comstar work become available. While I'm from the era, I certainly didn't see or know everything of the time, particularly the 4-bit era just before my engineering days. Intel's earliest 4004 literature, talks about use of 4004's to replace random logic, to produce controllers that could be manufacturer-reprogrammed. (Not by the way, user-reprogrammable, in fact 4001 ROMS were mask-programmed.) The 4004 and many other early microprocessors, were jammed into already-existing analog/digital logic instruments and even minicomputers. They replaced some user-interfacing logic for displays, keyboards, serial, data transfer. Later, they replaced the wired-up operating logic too. Microprocessor companies described and promoted their microprocessors in their application notes and press releases; early emphasis was to replace "hard-wired logic" for manufacturing and development convenience. The idea of "computers" evolved in many ways, to be brief about it. So calling something a computer begs the question of what computers were or were not at the times referenced. As far as what was produced when, and how early? Well, some company is chronologically first or second or third, in some way, of some kind of use of some microprocessor. I think it's all interesting, and since I am or was a digital engineer in the 1970's I have my own experiences of the period. The literature and media of the period, the artifacts themselves today, once found and referenced, provide first-person and empirical evidence. Those are my go-to's, so I have a lot of contexts to consider. Regards Herb Johnson -- Herbert R.

Founded in 1957 by Ken Olsen and Harlan Anderson, DEC was one of the most successful computer companies of the 20th century, reaching nearly $14 billion in revenue and over 120,000 employees worldwide. Their seminal contribution - the minicomputer - was the revolutionary bridge between large-scale mainframes and personal computers. Blending a non-traditional business culture with a robust line of commercially successful computers, DEC made computing accessible to multiple new markets and changed the way society used technology. In addition to being smaller, faster, and cheaper than mainframes, the minicomputer was accessible to non-specialized users. Their 12-bit PDP-8 was the first commercially successful line of minicomputer, with over 50,000 units being sold

With the exception of the Selectric, I grabbed what I could see, but the piles of stuff could certainly be hiding more. Again, I saw boxes of 5.25 inch floppies but no computers. I didn't have time to chat with the sellers, but they didn't seem to be your usual estate sale company types. The Selectric, Silent 700 and teletype were the only keyboards that I saw.

Just snagged a couple of nice printing terminals...
by William Sudbrink 05 Jan '24

I stuck my head in a nearby estate sale for a couple of minutes. I wish I had had more time. A real hoarder place, shoulder wide paths through shoulder high piles of stuff. I got a Model 43 Teletype and an original TI Silent 700. Twenty bucks total. I passed on a big orange Selectric II (there wasn't room in my car for it and I don't really have the space for it here at home). There were some computer science texts in bad shape and lots of boxes of used 1.2 meg 5.25 inch floppies. I'm sure there is more stuff I couldn't see without digging. I may go back for a second look tomorrow. If somebody really wants a Selectric II, contact me. Bill Sudbrink -- This email has been checked for viruses by Avast antivirus software. www.avast.com

VCF East 2024 Atari Classroom
by Dean Notarnicola 04 Jan '24

04 Jan '24

All, Being that it’s the 45th anniversary of the release of the Atari computer and continuing the still popular 6502 theme, I will be doing an Atari classroom similar to the Apple classroom that was done two years ago. I have a quantity of Atari computers that I am reconditioning in advance of the class, but I’m anticipating that I will be needing more working units of any of the Atari 8-bit family. My ask is that if anyone has machines to sell/lend/donate for this effort, it would be greatly appreciated. As well, I welcome any teaching assistance from anyone who has experience with Atari BASIC and/or assembly language. The courses will be similar to the Apple classes with beginning and advanced BASIC/assembly and an overview of the system architecture. Thank you, Dean p.s. - Planned for next year is a CoCo classroom to give the 6809 some love, so I’ll be bugging everyone again at that time ;-)

InfoAge hours around VCF East
by Josh Knight 01 Jan '24

01 Jan '24

I’m planning my first visit to VCF East. I’m interested in checking out the other exhibits that InfoAge offers while I’m in the area (traveling ~9 hours), but I’m wondering how realistic that is. Are the exhibits open before/after VCF? Are they open during VCF? Should I plan an extra day or two? Any suggestions? Thanks Josh

Fiber to 9011 / 9036
by Martin A. Flynn 31 Dec '23

31 Dec '23

Ken & myself were on site today for a few hours, the fiber to 9011 and 9036 is active, equipment installation in 9011 pending (no access) , unsure if VCF installed the 9036 equipment, or if it's still needed. Had to use a fiber pair from 9010 to support 9011 as it was not part of the original project scope. Happy New Year... Martin

I need to focus my time with the overall planning as there are a little over three months to go. Most of the work happens before the show and I'm just one person looking for dedicated volunteers. If you are interested in volunteering let me know and sign up here: https://docs.google.com/forms/d/e/1FAIpQLSeF33aZBQL57vymsP98JWazK1h1IcHHqbM… Thanks!
