More on that PBX...

Okay, I got the thing up to a lighted room, cleaned it up, and I'm going about checking it over. So far, I've determined the following: The computer itself is a 16-bit discrete-logic machine, with scattered ICs. It spans about 7 or 8 boards for the CPU itself, and about 16 or 17 for 64K or so of RAM. Dunno what it runs, as I can't power it on yet, but it boots from a magnetic tape cartridge. (I think it's a QIC-02 cartirige, aren't those the ones about 1/2" thick, 5-6" wide, and about 3" long?) Anyway, I haven't found a TTY connection yet, but I did find a Bell answer-only modem inside the rack (In fact, it had broken free of it's mounting and was bouncing around inside the rack) so it does have one somewhere. The main problem at the moment is the AC input box appears to be dead. No output when power is applied. I'm getting a second person to watch me open it tonight, that way if I do something stupid and nail myself, there's a second person to run for help. Replacing the AC box with a power strip won't help either, it appears to generate all the miscellaneous AC voltages required. If I get ambitious, I may be able to replace it, but I don't wanna unless I have to. More as I find it out... -------
