SysSrc swap / TI SN76489 Colecovision sound IC
by Ethan O'Toole 24 Apr '25

Anyone have a spare SN 76489 colecovision / Tandy 1000SX sound IC I could buy from you at the system source swap? My colecovision one died, I tested with one from my Tandy 1000SX and narrowed it down. Figured I would ask. - Ethan

Sol 20 with Toyota Monitor $1500
by Christian Liendo 23 Apr '25

A guy I know is selling his Sol. He is in Brooklyn and he wants to sell this and have it picked up. He won't ship and I don't blame him. I have a picture but I know the email thread doesn't allow pictures so I can send to you Here is his post Processor Technology Sol-20 Terminal Computer + Koyo Monitor + Manuals Selling a piece of digital history. Purchased in 1977, it predates the Big Three: the Apple II, Commodore PET and Radio Shack Tandy TRS-80. It includes 24K RAM, GraphicAdd board, Music System board, Koyo Monitor, 9 manuals, data cassettes (I don’t know if they are still readable). Sadly, this beauty no longer functions properly but the right hands might be able to bring it back to life. It does power up, but the output is a random series of characters (see photo). All IC chips are in sockets, so it’s possible that reseating them might help, but I’m no hardware expert. It is being sold as is. Cassettes: Basic 5, Extended Cassette Basic, Music System, Gamepac1, Games. It’s a beauty to display for a collector or a promising project to restore for a techie.

NavCore (Navigational Computer Systems, Inc.)
by Jeffrey Brace 23 Apr '25

VCF recently acquired a donation from the daughter of John Paul Jones, Jr (now deceased). Apparently he was the founder of NavCore which operated out of Norristown, PA. He was a prolific inventor who had as many as 100 U.S. patents (I've only found 50 or so of them). We went through most of his donations which are mostly paper materials such as brochures, company reports, patent applications, books and photographs. We received a few of his computer inventions as well. So far no one I have talked to has heard of this company. I'm just curious if anyone else has. We are still researching, but there are lots of interesting things in the materials. Jeff Brace VCF National Board Member Chairman & Vice President

mpja.com Marlin P. Jones is shutting down after 40 years of electronic surplus. So few surplus electronics stores remain: Goldmine, who else? At least I got to visit the West Palm Beach, Florida store when I could. -- Jeff Jonas

SGI IO9 card available?
by David Riley 21 Apr '25

21 Apr '25

Hey all, I have a coworker who needs an SGI IO9 card (used in Origin 350 systems, among others) rather urgently. Does anyone have any available? He's found one potential option from a parts vendor, but it's a -005 rather than the -006 in the system, and it's unclear if there's any difference (the National Stock Number registry indicates all variants from -001 through -006 are compatible, but that's not exactly gospel). If you can help out, he'd love to hear from you, and I can put you directly in touch. Thanks! - Dave
