I was wondering if there are any S-100 floppy disk controller boards that
have the following set of features:

1) Board buffers a sector, and is intelligient enough that the CPU can
issue a command, do something else, and come back later for the data in
response to an interrupt (similarly for writing).

2) Works with single and double density drives.

3) Works with 8" and 5 1/4" drives.

4) Works with 48 tpi and 96 tpi drives.

5) Items of flavors in (2), (3), and (4) arbitrarily mixable.

6) Controls 2 to 4 drives.

Anybody know of boards meeting all or most of these specs?  (1) is important
for good performance in a banked multi-user system.  Thanks -- Eliot
