While it wouldn't be universal... at least for certain platforms,
wouldn't it be simpler to replace the MFM controller chip(s)
with a circuit that simply accessed an IDE or SCSI disk instead ?
i.e. replacing the MFM chip in an AT&T 3B1 with a daughter
board that then had a 50 pin IDC header on it for connecting to
a SCSI disk (or disks) ?
How hard would that problem be ?
It wouldn't be a universal application... would only work effectively
with systems with socketed (or at least through hole) chips... but
I'd think it would be much simpler, no ?
Anyone ever attempt something like that ?
