Commando PCB Repair

After replacing all the nasty sockets (single wipe rubbish) this Commando board worked but had vertical lines through the player and enemy sprites.

The sprites are handled by the bottom pcb, after ruling out the ram the trusty boardmaster flagged a 74LS163 @5K.

Testing it again out of circuit confirmed it was bad.

Luckily I had a single replacement 163 in my miscellaneous TTL drawer.

I fitted a socket and the new chip.

Repair complete.
