SCSI - 200MB or 88MB with "C" on the front (stands for compatible) or 44MB drives.
I have one working 44Mb. One very sick corroded 44Mb, a 200C which wont eject, and a 200C which wont spin up properly (but worked correctly last week). Would be great to get a couple more working drives. I'll be attempting to repair my failing ones but a backup would be nice. I need a minimum of two working units.
Happy to buy untested (as long as price reflects) or trade for stuff.
