OK, looking at the 630QB tech manual now, which seems to be where these
were lifted from... and of course it points out that the LEDs on the M7606
correspond to the hex codes on the panel (i.e. my four red LEDs with the
middle pair flashing on and off equate to the alternating F-9 I'm seeing on
the hex LED)
The green LED on the CPU board is 'DC OK' and I'm also getting a green 'DC
OK' on the front of the machine, and it seems odd those would be lit if
there were a DC fault... but who knows. No explanation of the flashing
codes, either; the manual seems to imply that it steps through in sequence
down from 'F' and will stop when there's a fault.
