I can tell you my extremely limited few-minutes experience with
friend's SVD - it doesn't handle Locksmith's "Fast Backup". Probably
because of the funky way to detect head movement - look at the
schematic. And some Apple ][ software likes to do naughty things with
the controller.

Just by memory, I think with my firmware I have achieved very good
transfer speed (better than CFFA??), and it can be further increased
by skipping CRC. Only DMA can provide faster transfer.

I have developed alternative firmware for PD8, which was written from
scratch.  There were prepared some nice options and it was roughly at
a 50% completeness. Haven't touched it for about 7-8 months, but I can
return and finish it, provided there is:
  - enough interest in people already owning it
  - people wanting to try newer firmware and provide testing/feedback
  - developers wanting to (ab)use it as a co-processor
  - some new folks to try it

Please state your opinions here, as they will shape the PD8's fate -
new firmware/features, board re-spin, etc.
