Config info on HP1000 memory?

Try installing only one memory array board, with all jumpers installed.

HP module addressing jumpers are installed for a logic 0, removed for a
logic 1.

Make sure your memory controller is in the bottom slot. I often find
the memory system is 'happier' if you
place the first memory module near the far end of the memory controller
ribbon cable, and always suspect
that ribbon cable. Its not uncommon to find a bad connector or two, so
you may have to move the memory
module to another slot, ot try flipping the ribbon cable upside down.

We'll get your HP running again.

Any interest in trying to boot HP-IPL/OS?
