The machine is a DEC uVax 3500 (the > KA650 processor). It should work, though you may need to make some minor driver changes. The KFQSA looks like multiple UDA50/KDA50/etc. Be sure that the drives are configured appropriately (via the ROM monitor on the KA650). The changes you'd need would be to handle the controller model that you receive when the driver goes "what are you" to the KFQSA. Each MSCP control- ler has a unique model number. For reference, the UDA50A is type 6, the KDA50 is type 13, the RQDX3 is type 19, and the KFQSA is type 21 (for disks).
