Purchased a Sony FSV-M3/640 in working order less drives. It also turns out the documentation, software, and disk transports are missing. So the system does post but I can not find drives for it. The boot screen shows the Promise PDC 20275 ultra/133 message. The 640 would seem to indicate 4 x 160 ultra 133 drives but the dual chip PDC20275 controller has 80 pin sca female connectors. So far i have not found any adapters that will convert this to ultra/133 ata. Please help.
