I've got my copy of the field engineer handbook open and I can't find an
error code listed for the 4/1xx series that matches this. If the first four
LEDS were like as you've shown with the last four blank, this would indicate
that there's a fault with the MMU chip.

However.... What you might like to try is switching the board to diagnostic
mode using the switch labelled NORM/DIAG on the panel, then connect up a
serial terminal to port A (9600 bps, 7 bits, even parity) before you turn
the machine on again. This way you'll see all the self-test messages and you
can get a better idea what is wrong.

It could just be a problem with one of the SIMM's - either one that's died
or one needs re-seating in it's socket.

Regards,

Craig.
