How would these have been formatted since the RQDX1/2 doesn't know anything
about RD31 or RD32? The Pro tech manual describes a formatting function that
lets you lay down a low-level format for a given track. Could a drive be
formatted in the field using the Pro or did the drive just come
pre-formatted?
Well, when I fiddled with an ST-251 in my Pro350, I wrote my own
formatter. The register layout is close enough to the traditional IBM/PC
AT type controller that it wasn't particularly hard.
I've lost the code, though, so I can't really offer anything beyond
moral support. I do, however, have the original PC formatter code that I
started from (in TURBO Pascal 3.01), if that's helpful (I would suspect
not).
