Need switch settings for it. Mine's acting funny and I think the switches got played with (The SCSI controller works fine, and the TC doesn't, swapping slots doesn't help, only other things in the backplane are two DZ11s.) It's a Emulex TC12 UNIBUS tape controller, with a 1600/3200 BPI Pertec 9-track drive on it. Drive is known good. I/O with the drive loses about half the time. (It just hangs RT-11 forever.) -------
