Sequential circuits samplers

Hello list(s),

I would like to write a program to read & write disks from a
Prophet 2000/2002 sampler. To this end I'm looking for
information about the disk geometry (sector size, sectors
per track etc.) and the structure of the data on the disk.
I've checked the service manual, but it didn't have anything.

If anyone can help me, that'd be great. I would of course
make the program (and its source) freely available.

I apologise for the low analogue content of this message.
And for cross-posting. And for wearing these shoes with
these pants.

Cheers,

John :^P
