DSSI in a BA123?

Ok, this is the challenge. NetBSD runs flawlessly on my KFQSA in the 3900 but hangs using the SIGMA RQ11D in my uVax 3. Since I have an "extra" KFQSA (now knowing how to configure it!) I could put it into my BA123 but that appears to be a challenge when no documentation is present :-) Some questions: 1) The Controler <-> drive cable, can I crimp a three appropriately sexed IDC connectors on to flat ribbon cables for hookup? 2) How to hook up the drive control panel? The 3900 has a connector that is wired to the bulkhead and the drive, it also holds a "unit number" plug. The BA123 has its normal DRIVE 0 WP/Ready control with a different sized connector. Can I adapt it to the RF7x series drive? How? 3) DSSI terminators connect to the scsi like DSSI connector, if I put a SCSI 2 connector on my cable can I use an active SCSI 2 terminator instead? As always, thanks! --Chuck
