Oh wait, your "Vax 4000-200" is a KA660 in a BA215? Then the internal DSSI is
connected via the 50-pin connector piggybacked on the KA660.
Not via the BA430 backplane. Connecting the KFQSA's external DSSI connector to the
other end of the DSSI bus, via an external DSSI cable, should still work.
The possible problem with just disconnecting the DSSi internal cable from the CPU and
leaving it hanging, is no longer terminating that end of the DSSI bus.
