Hi I managed to locate an RRD42-AA (ie real Dec for 14 Pounds UK (27 Dollars US)) I aready have a Yamaha SCSI drive in an external powered case. I also managed to locate the correct cable. (50 Way Centronics male to 50 way D type male double density pins and clip type) This fits the SCSI connector on the back of the external box and the other (big) end goes into the KZQSA So... When the cable arrives try the Yamaha drive. If its no good. Then remove the Yamaha drive from its box and replace with the RRD42. This way I end up with one or maybe two working SCSI drives.

I have a XM-3101 (same as the Sun SL-CD) that boots my VAX4k2 (KZQSA) VAXstation 3176 (int. SCSI), SPARCstation IPX, IRIS Indigo, etc. etc.
