DEC H7260 PSU fault

The TK50 drive sits there with a rapidly-flashing light (I saw someone saying that's likely the tape feed band or just dirty heads, so it might be fixable). The RD53 drive... hmm. I tried powering it without it plugged in, just to see if it at least sounded healthy; it spun up to a "sensible-sounding" speed for maybe 15 seconds, then spun down again. I tried again, and it remained spun-up, but the initial spin-down was hardly encouraging. With the drive actually hooked up to the controller, I'm getting "?54 RETRY" messages when it's trying to boot - however, I'm not entirely sure what device it's trying to boot from! Maybe it's attempting the TK50, or via Ethernet. I still need to read up on that and work out how to force it to attempt a disk boot. One other issue is that the RD53 was in the second bay (and hooked up to the associated cables) - it makes me wonder if it was just an auxiliary disk, and the system originally had another drive in the first bay (containing actual OS) which has been removed. Yup, I *think* I've got my head around how that works! (along with the special slots for CPU/RAM) cheers Jules
