Well, I am trying to do exactly this. My limited electronic skills mean I
am not going very fast, and I lack a logic analyser which would really
help, but I have reached the point where the MicroVAX 2000 formatter can
recognise an RD31, RD32, RD53 and RD54 by counting tracks. I am some way
off getting actual data in and out though....

to an MFM controller. That would have a much wider impact than SCSI.

Just saw this on Erik's web site, and
hadn't seen it mentioned here
http://www.codesrc.com/mediawiki/index.php?title=SCSI2SD
Currently getting around 900kb/sec R/W
There's some discussion going on right now on the cbm-hackers list
about adapting the firmware for the SCSI2SD to stand in for the MFM
drive and SASI bridge in the CBM D9060 and D9090 drives (SASI isn't
(exactly) SCSI; the CBM "DOS board" doesn't implement parity, ATN, or
have termpwr, and the DOS firmware formats the media to 32-sectors of
256 bytes per track). Solve those issues and D90x0 drives will work
for many years to come.
It's a shame that no one has yet built one of these interfaces that can
