Found what looks like a 2Gb drive in the Alpha when I was cleaning up the computer room a little yesterday. I had forgotten it was there.
Also discovered that the alpha appears to be having some power supply issues. Oh well, I can use the drive in the sparc, and start working on getting the AlphaPC running. It needs a floppy and a CDROM, at the very least. OK, a CDROM, since the floppy looks non-standard….
