Are the samples held in RAM in the drum machine, or what?
Is there any way to load samples except through the expansion
connector?  What does the expansion connector look like?
(Maybe it's a serial link.  ;-)

If you could get the machine to regurgitate the samples, and
capture them on a PC, it would not be difficult to determine the
format and rate.
