From: J. Eliot B. Moss <EBM@mit-xx.arpa> 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 -------
