A slightly different repair today. This is a Commodore PET 3016 board, the same board as used in the 2001N and 30xx and 40xx series (but not the 12" monitor 40xx series). It's not working, but it looks like it has had a lot of work done to it already. I normally try to avoid working on boards like this.
2022 Update: PET ROM/RAM boards are still available from my SellMyRetro store.
