Hi, I've been lurking for a week or so. I'm not a computer guy per se...my brothers got that! but I pick up some stuff. I have basement full of mostly mid 80s 8088 boxes, as well as some Kaypro cp/m machines, and some newer wintel machines. See: http://www.primenet.com/~jforbes/ for an (incomplete) overview. As for Nixies and home brew computer displays, one of my brothers is into Nixie tubes, so I've kept a lookout for them...and recently found an old piece of Danish test equipment with 5 nixies in it, which was destined to go to the landfill. It had been sitting outside, and was not in very good condition...but I pulled the display board out, and it seems to be usefull (see link above for a pic). If you want to drive Nixies from a TTL BCD signal, just score some 74141 type devices, they were made for the task! Also....I was digging thru some old stuff while cleaning in the basement, and found a Motorola 6802, 1982 vintage. I wonder if it's usefull? Jim Forbes in Arizona
