A co-worker has asked if it's possible to use a typical PC hard drive in a Rolm Mod 10. He believes the older PDC/drive assemblies with the blue diskette eject button were SCSI - and the newer models with the white eject button were IDE. I assume we'd need new newer model PDC, which I think is the 90595. Not sure if the diskette drfive would have to be changed to the newer model as well.
