This past weekend I picked up an old PS/2 machine. It's a Microchannel system, a Model 65sx (I think). The only thing missing in it is the hard drive. It has one of those 3-1/2" drives with the full-length card-edge connectors on it, I think 50 pins wide or so, that provides all connections including power. I would like to get it up and running just to have around as another working system (also got a Compaq Portable III at the same auction for $10 in a leather case!). Any suggestions where I could find such a drive easily? Is this machine's HD interface an ST-506 variant, EISA, or what? Thanks. (also got six complete, loaded Ultra 5 boxes at the sale. Exciting times...)
