I'm amazed - someone who's heard of these things! :) Well all I have are the basic Alphatronic PC units (three of these I think, although I seem to remember that the keyboard status on two of them is far from perfect - these things used to be really abused when used as terminals), one original shipping carton, two manuals, and that's it. Oh, did these things come with monitors at all? Most of the ones we had at university had 12" mono screens hooked up to them, but I don't know if they were original or not (I have a couple of these - similar shape to DEC VT320 terminals). The manuals I have (IIRC) both mention that the systems can be expanded to run CP/M, but no mention of how or what was needed; there's no pin-outs of the expansion port, cartridge slots or anything. hmm, so what's the difference between the two? Mine are all badged "Alphatronic PC", but I checked with the university staff before I left and they never had any floppy / hard drive systems with them... (This is where I really hate not having my collection around at home, it's been so long since I've powered one of these things up I can't even remember what CPU they had. I vaguely recall that they had a lot of fairly non-standard chips inside though; the CPU may have been a rebadged part of some description) cheers Jules
