4040 startup error codes?
Well my trusty 4040 drive has finally given up on me. This morning I get a sequence of 8 flashes on all 3 LEDs and no drive motor spinup. Does anyone have a list of what these sequences mean?

Thanks for the link, I'd found a similar table elsewhere but this confirms I've probably got faulty RAM. One chip had been replaced previous to me acquiring the drive. I've got some 2114s, sockets are on order.

OK, after a rather fraught time de-soldering (I hate removing chips from boards) I've tested UE5 and it's certainly faulty. Dropped in a known-good replacement and the drive now powers up properly!
Here's a picture of the 6264 to 2114 converter I built to test the RAM
