I have a commando with corrupt backgrounds and flaky/missing sprites.

This is a bootleg board but as far as I understand it's a 1 to 1 copy of the original 3 board stack.

I started with the background issue:




The background is handled by the top board. Looking over the chips, I spot a few fajitsu's, so I started on them. Finding pin 19 stuck high at 3E on a ls273, I decided to pull it and throw it in the tester.



Socket and new chip, fixed:





I'm suspecting the missing sprites are a ram issue, but that will have to wait for another day.

Looks like you've got some lines going through the tree, good job so far. Keep an eye out for more fujitsu ttl. Smile
