<Didn't the very first 3100's have MFM controllers? I could have sworn tha <I've heard that they did, but I've never seen such a beast. Yes they did... SCSI to MFM bridges. <One with a TLZ30 (Tape drive for TK50's) or a CD-ROM would be nice. Mine <has the RX23, and I quite honestly have no idea what use the floppy drive <is. Well a SCSI Cdrom is easy enough to find all it has to do is support variable length block sizes, many do. TK50GAs (or is it FZs) work with them too as do TLZ04s, a slew of DLTs and SCSI tapes.
