OK, I've tried it with all cards removed, all memory removed, with and
without the 1M simm on the motherboard, and without the keyboard or
terminal plugged in. Every try has given me the same damn results. If I
can't get this to work, I might try just using these boards in my 55L
instead...

What exactly is the boot sequence, and what is supposed to show up after
120 and 124 that the 400 is pre-empting?

Also, there's an empty ZIF socket on the mother board next to the Power
processor chips... what is that for exactly. Also, there's a pair of
slots on the motherboard that 'look like' PCI slots (look to have
identical keying and size, but I haven't bother trying to fit a card in
yet to check.

Any more ideas? Could it be a power supply or monitor rom problem?
