Ok, finally got a moment to put together some bits in my uVAX 3900 in the BA213 cabinet. I've got it built as follows (from right to left) KA655 32MB Memory 32MB Memory DECSQA (ethernet) KFQSA (DSSI) TQK70 (TK70 contoller) Then wide open space. :-) [meta question, presumably DEC had fill plates for the empty slots?] In the top part I've got a TK70, and two RF71's. The RF71's are connected to the KFQSA via an internal cable that daisy chains first the rightmost drive then the left drive and then ends at a bulkhead that has a mini connector (looks like SCSI2). On that connector I've got a DSSI terminator plugged in. When I boot the cpu does all of its diagnostics but it doesn't "see" the KFQSA. One of the drives blinks fault the other rattles around a bit and then blinks ready. Some questions: The front panel has the disk lights bulkhead configured for three disks. I connected the small connector of the rightmost disk to disk one connector and the left disk to the second drive connector. Is that correct? When I type SHOW DEV to the uvax prompt it show the ethernet and tape but NOT the KFQSA. Is that normal if the disks are not inited? When I type Megan's command "SET HOST/MAINT/QSSP/SERVER 0" to access the internal controller on the KFQSA I get ?28 UNK SW Any ideas anyone? --Chuck
