Update: It isn't the BPROMs.
    Since my trustworthy Beeprog doesn't work with the D3625 (older than
earth itself!), I had to create a small dumper to read the BPROMs:

    Once read, I found some differences to the original BPROMs that runs in
the MESS emulator. So, I renamed my BPROM files to the MESS standard,
and...It ran.
    :oP
    So the problem is the 8086 itself, one or more RAMs (P2142) or some
phisical problem on the board.
    I will repair it! :oO
