Sly DC already scanned everything for CV including PCBs. He is only missing PCB scans for Monster Block and Elevator Panic since he doesn't own the games. I think you own these so PCB scans for both of them would be nice I guess.
He also started to post scans for HMG-7900/SD-200 which is a similar system. I was actually going to send all my HMG-7900/SD-200 stuff for kevtris to have a look at it, but don't seem to be able to contact him lately.
