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

TRS-80 Home Automation System - $300 (Belmont) on Craigslist
by Herbert Johnson 23 Jan '24

I have a box of X-10 items myself, all but given to me at a hamfest a year ago. It's pretty out of favor but not at all rare. If someone wants more X-10, email me directly, not here, email email email. I'm reluctant to discuss issues and details about X-10, Web homework and old books will inform you, ask wiser heads about it. regards Herb -- Herbert R.

Hi all, I have two sets of TI 99/4A computers and accompanying PEBs that I'm looking to sell. Would prefer not ship them because of weight. I'm in northern Delaware but I'll also be at the repair workshop at System Source this Saturday. Contact me off-list if you're interested. Thanks, Paul rickards(a)gmail.com

by Gregg Levine 22 Jan '24

Hello! Actually I agree. It turns out that style tty was the default device for communications back when the camp was still in business. Now what is a velociraptor doing walking around Infoage wearing a sweater and a lined raincoat? ----- Gregg C Levine gregg.drwho8(a)gmail.com "This signature fought the Time Wars, time and again."
