all three are untested. 2 have zero acid damage and the other one has a little near the battery holder

$35 + shipping for each of the nice ones
$25 + shipping for the one with some acid damage ( see pics)

Just so people know what they are buying, the first two are Defender MPU boards and the third is a Stargate MPU missing the 6809 CPU chip. The Defenders will only run Defender and the Stargate MPU will only run Stargate unless you make some hardware mods to upgrade it to a Rev B motherboard.

That is an engineering fix for a board f'up. I don't remember the details off hand, but it fixes a problem they had with that run of boards. I just pulled the schematic and it looks like it has to do with the CMOS memory protect.

Sorry for the off topic.

Of the new boards,
#1 is a Rev B motherboard that will play all games from Stargate to Splat! minus the 6809 CPU chip.
#2 is a Rev 0 (Stargate) board minus the 6809 CPU chip and the chip at 6F it looks like.
#3 is a Rev B motherboard that has a modification (daughterboard) that I have never seen before.
