Ok - Just based on C/H/S it seems like such a potentially obvious replacement, I figured that there must be an explanation as to why no one ever wrote about it. The 506 drives I am using are NOS, they are in great shape and return "1700 S" code in IBM XT diagnostics. Maybe if I understood better the custom jumper wiring needed to get a Tandon 602s to work in a Tandy 5MB external drive (not needed in the D9060) that may shed a clue about what needs to be done on the ST-506 in a D9060.
