Everybody is probably waiting for me to answer this... 1) It has a 600 Rev. B board in it. It's identical to a metal case C1P. Obviously, if it has other add-on boards, say a 610, 620 or 630, then it will have additional capabilities. Open it up and see what's in there. 2) I'm hacking CP/M on an IMSAI right now, but when I get tired of that, I'm going to be putting about 40 C1P programs (a lot of them from Aardvark) on a CD and distributing them for cost. Eventually, I'm going to put up an OSI web site which will have .WAV (or MP3 or whatever is smallest) files of software available so you can make your own tapes/CDs/whatever. Bill Sudbrink
