    If had an ST (FM or E) I might look for an ACSI->SCSI
host bus adaptor (I think a popular model was the "Link"). I have
a vague recollection that there was at least one that supported parity,
which should work with a wider selection of peripherals.  One of the nice
things about the Mega STE was that it had something similar built in and
even had a bay for a 3.5" hard disk drive.
