May it be possible that the Crimson uses High Voltage

The base I/O on 4D-series (including Crimson) machines was SE SCSI-I
(WD 33c93) on the IO3B. HVD can be installed through VME options, but
was not standard (as it was in the later Onyx/Challenge).
The OP may want to look at Gerhard's page about the Crimson
(http://sgistuff.g-lenerz.de/hardware/machines/crimson.php), which
gives more details about the SCSI configuration.
