The multirom just replaces the U1/U2 and U6 roms, you still need the processor, pias, and memory chips that are missing from your board.

@Dave2084 will say if any of that is wrong!

That's bang on!

I did intend to work on a version that replaced the 5101 and 6810 with an NVRAM but haven't had the time yet ...
