Speaking of Repairs - LS ADM31

Sorry, Tony... but I thought "What the heck - I need a terminal for one of my VAXen, and I have these two Lear Siegler ADM31's that have been garage-bound for over a year... (rescued for $5.00 USD for both) So I just "plugged 'em in" to see what would happen... [Well, not quite - I at least popped 'em open, and reseated the socketted chips first...] One seemed dead other than the caps-lock light would toggle as you pushed that key (so there's hope), but on the other, the video seemed to work, and I got several screenfuls of '8' and '0' [zero] and inverse-video '8' and '0' [zero]... and there it sits. Just a quick background on the box (from what I could view from the inside... Firstly, its a damn computer in it's own right! It's Moto6800 driven, with 2 EPROMS (2716, IIRC) for the program & 1 EPROM for the 6845 character generator... a couple K of RAM (don't remember specifics) and lotsa 7400 series TTL. Does this sound like a normal failure mode of an ADM 31? (I have absolutely no dox for the machine...) Could it be bit-rot on the EPROMs, or is this normal startup if there's no serial cable hooked up to it? I have to make a cable from my VAXen to the RS232... I want to make sure the terminal is worth diddling with (read: easy enough to fix) else I'll just hook up the [dusty] Pentium 100 and run a terminal proggie until I have more time (read: in a few years)... BTW, test equipment I have include a DVM/Freq counter & a 'scope, but sorry, no logic tester... Any help will be most welcome! TIA, Roger "Merch" Merchberger P.S. I'll give more info when I get home... -- Roger "Merch" Merchberger --- sysadmin, Iceberg Computers Recycling is good, right??? Ok, so I'll recycle an old .sig.
