Alright. Two dead Commodores.

Over 15 years before I was born? ✅
No idea how BASIC works? ✅
Internet at the ready? ✅

So far I've checked various chips for visible damage, and nothing except a blown fuse on both machines. Apparently it takes dual 9vAC and single 5vDC. The 9 powers the SID and the video output, the VIC-II heatsink is off, and I've tested the PSU voltages and one of the 9v's is dead. I'll be getting new fuses and a new PSU soon. Any recommendations on other things to check or things to do when they're done? Pic included because why not.
