If you have a KA655 VAX CPU, or the SIMH version, you can run the configure utility to calculate what the CSR address and vector assignments should be for the set of devices you have. For example: VAX simulator V3.8-1 sim> load -r ka655x.bin sim> boot cpu KA655-B V5.3, VMB 2.7 Performing normal system tests. 40..39..38..37..36..35..34..33..32..31..30..29..28..27..26..25.. 24..23..22..21..20..19..18..17..16..15..14..13..12..11..10..09.. 08..07..06..05..04..03..
