IBM PS/2 Model 70 or compatible floppy drive wanted (Or help with current one?)

[Gary Sparkes]

Ah, just so we're all on the same page here.... The drive i'm looking for
seems to be "extra" special.... mine's got a ribbon cable connecting it to
the card edge connector .... same connector as these two pictured drives
but slightly different configuration. Apparently the drives shown are
compatible, however -
