WTB: Decwriter III (LA120)
by W2HX 26 Jan '24

26 Jan '24

Hi all, I'm looking to purchase a working decwriter III (LA-120). Keyboard version would be great, but an RA (printer only) version would work fine too. No computer room would be complete without one! Willing to drive 3+ hours. I'm located about 30 miles north of NYC. 73 Eugene W2HX My Youtube Channel: https://www.youtube.com/@w2hx/videos

Join our Museum Team! Its a blast showing folks the computers and telling them about the tech development over the decades. No pressure, just good times. Its even more fun to bring a friend along and spend the day exploring our enviable batch of computers from the 50s,60s,70s,80s, and 90s. All you need to do is show people around the museum, show them the activities we have and if you want to, demonstrate some of the machines. Show and Tell! Easy peasy. Learn as you go. We are open Wednesdays, Saturdays and Sundays 12-5. No set schedule, you sign up for when you want to come. Quarterly, monthly, weekly... its up to you. Contact me off list. -- Douglas Crawford VCF Mid-Atlantic Museum Mgr InfoAge Science & History Museums 2201 Marconi Road Wall, NJ 07719

I've got one with expansion RAM and floppy adapter that will likely be available in the not-too-distant future.

System Source Workshop - bringing an OSI Challenger 1P
by Crawford Griffith 26 Jan '24

26 Jan '24

Folks, I’m bringing parts of an OSI Challenger 1P that I hope to get running and assembled. I bought this at the Berryville VA hamfest years ago. It was in a home-built case that was falling apart. There were quite a few mods to the C1P, I think there is a custom monitor ROM with a selector switch, etc. I hope to remove the mods, get it back to stock configuration. It also has the expansion board with additional RAM, floppy controller and a floppy disk drive. I have proper OSI cases for both the C1P and disk drives. Hopefully, I’ll get some of it working! -Crawford

Re: [vcf-midatlantic] TRS-80 Home Automation System - $300 (Belmont) on Craigslist
by David K 23 Jan '24

23 Jan '24

I agree that the system is cool and it's fun to have so many components together in one listing (even if the price skews high). And while people on this list might be jaded by the quality of the technology, I think a lot of less tech-savvy folks (like myself) would be impressed with what 'smart-home' technology was back in the 80's.
