RAM board, missing one ROM.
When I replaced the ROM with a known working one I get a 132 error.
All chips re-seated.
All sodler joints reflowed.

$20


Defender ROM board.
I broke the pin off chip #2. (see pic)
Nothing else done to this board.

$20


Heat synch. Untested.
Gnarly looking molex.

$10


Will combine all for $45.

All prices in USD. Shipping extra.
Will ship internationally...as always.

Whats the mpu board id/revision number and which prom is missing the prom 2 or prom 3?

Also, by chance you dont have the linear pcb that goes with that heatsink anywhere do you?

The revision is D.
There's no missing chip on the Defender, just the broken pin. AFAIK, all Defenders are 'missing' the one chip.
