Ah, sorry. I didn't get it. You want it to be universal.
I was thinking you could act like most common controllers and encode
data that was actually on a server, a sort of "nfs server with an st-506
interface".
I never thought about it the way you are proposing... hummm... :-)
thanks!

(lately I've been making MSCP disk images with simh and then dd'ing them
onto zip drives and booting them on an pdp-11, so you can see why I'd
be in the 'server' mindset. I really want a SCSI server....)
You'd need to encode the bits correctly so the data/clock seperator
That's just what I'd not want to do. You can't make any asumptions about
the clock/data encoding scheme if you want this emulator to be universal
(after all, a real ST506 doesn't do anything to the pulse stream other than
record it on the disk, unchanged [1]).
That was the reason for the high (10*, 8* would probably be OK as well)
sampling rate. Just record the pulses to memory, then play them back.
