You'd need the expansion plate, I believe, because it provided the interface to the external disk and the rudimentary SCSI for the TK50Z. Connection-wise, all it takes is a 50 pin cable from the 50 pin IDC connector on the motherboard to a 50 pin narrow SCSI disk. I bolted the disk into the compartment in the unit where the RD54 was (used rubber spacers under it to suppress the noise even more). ...but it still goes "rrrrRRRRRRRRRRRRRR!" when it loads heads! ;) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
