Re: [vcf-midatlantic] OT: time to downsize

I’ve finally gone through all the old Apple “i“-devices I’ve accumulated, but I haven’t listed them on the website as they definitely don’t fit the “vintage” moniker. That being said, perhaps some of you might also collect these or want them for parts/nostalgia? There are a couple of 1st gen iPads, a 1st gen iPad mini, various iPods, and a handful of iPhone 5 and 6 phones. Drop me an email if you want any more details. And still plenty of other stuff left - although I’ve been slowly selling off bits and pieces on eBay. - Bob Shuster > I've been regularly marking the sold and sale pending items, thank you guys so much!

(I had to do that recently for a relative.) On the electronics side, I've decided to concentrate on my vintage video game systems - and therefore sell off most of my vintage computer stuff. My collection includes mostly 8-bit stuff: TRS-80 Models I, IV, M100, etc. - Atari 400, 800, Portfolio, ST, etc. - C64/VIC20 - T/S1000 (including an unbuilt kit), Apple II, II+, IIe, IIe Platinum, IIgs - Wang WLTC - Mattel Aquarius - TI-99/4A - many others that I still have to dig out - plus lots of peripherals, disks, manuals, etc. Also have some newer Macs starting with a Mac Plus in an Apple carrying bag. > > I'm starting with you guys before trying to list elsewhere, although I may hit some of the dedicated FaceBorg pages (such as for Aquarius and Apple II.) I'm willing to ship some of the smaller items, but in general systems or monitors will need to be picked up here (near the Fort Washington exit of the PA Turnpike) or nearby, and cash or PayPal for payment. I may also consider trades for some of the video game stuff I'm looking for. > > It pains me to do this, but the clutter is getting out of hand, and I haven't touched most of these in years.

A 4004 Based Microcomputer the Comstar System 4
by Christian Liendo 27 Dec '24

27 Dec '24

A number of years ago I got my hands on a Comstar Programmer, it programmed roms for a computer called the Comstar System 4. I was told both the programmer and the System 4 were intel 4004 based. I asked around and kept getting told no computer was 4004 based. I really didn't do much due diligence just some searching here and there but I found enough to show that the computer did exist and was 4004 based. The website "Internet Scripophily Museum of Computing" has a page on the history of The Warner & Swasey Company. It's a decent timeline of the company http://ismoc.blogspot.com/2017/06/the-warner-swasey-company.html In "Auerbach Guide to Minicomputers" April 1976, the computer is mentioned on page 54 and page 70. On page 70 are the specifications and they show it being 4004 based. http://www.bitsavers.org/pdf/auerbach/Auerbach_Guide_to_Minicomputers_Apr76… In the IEEE Spectum May 1975 on page 26 the compiler and the System 4 are talked about having a 4004 https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=6368812 In the ACM's archives "Development of a portable compiler for industrial microcomputer systems" by LEROY H. ANDERSON The Warner & Swasey Company, it discusses the system and has images on the unit. https://www.computer.org/csdl/pds/api/csdl/proceedings/download-article/12O… And finally the Computer History Museum put the manual up for download. https://www.computerhistory.org/collections/catalog/102686568 I'm still trying to get more info, but I think this is some decent evidence to show there was a 4004 based computer in 1972

Re: [vcf-midatlantic] How did the System Source workshop go?
by Crawford Griffith 31 Jan '24

Folks, Reporting from my end of the tables (AKA the OSI corner) at the System Source workshop last weekend… Jonathan Chapman (Glitch) and Bill Dromgoole were working on the rare 14”Ohio Scientific hard drive that Glitch brought. They got the OSI CD23 hard disk to give up data. They captured 2 MB of data before the system reset but the presence of some FORTH code showed they were getting real data. The magic combination was the original OSI 590 disk interface card Glitch had restored plus Bill Dromgoole's 525 dual port RAM card. This combo started providing believable data at 15 minutes before the 9pm closing time on Saturday. Earlier Lou Ernst provided the LM311 comparator that eliminated the Track zero sensor from the gremlin list. Lou split his time between the main work table room and the DEC room. Bill D and Glitch helped me (Crawford) get my OSI Challenger 1P to boot. I got the extension RAM and disk board attached, after I got the RAM on the mainboard sorted. No boot from floppy disk yet, but we played with disk lines and found some step/load functions were working. I also got my MicroCoreLabs MCL65+ emulator to run on an Apple II+ loaned by Alex Jacocks. Dmitry was working at the same table as me. He was working on Sun 3 stuff getting some advice from Maki and others. Dmitry was showing a California Systems Star dual 8” floppy system he had found also. Sunday, Maki got the power supply fixed and got monitor boot out of his Techtronix 88k! And also got to the monitor ROM and console via serial port. Alex J and Jonathan Sturges can chime in on their progress if they want. Glitch (as usual) was helping basically *everybody*. David Gesswein also checked in occasionally from the DEC room and answered questions and gave advice. I met Justin who was working on Commodore 64 stuff, he was a first time attendee of a VCF workshop. Katheryn/Kat (sp?) was there with her Apple plotter and Apple II, trying to get it all working correctly. (Also a first time attendee). The System Source folks, Bob Roswell, Ryan Burke, Ryan Schiff, and others did their usual great job hosting. It was much appreciated! Sorry if I got any names wrong, and was not able to meet anyone. -Crawford
