My VIC-20 motherboards all look a little different. The most unique one is the Rally VIC’s modified Rev E motherboard (although you can’t see the rally car stripes from the inside). The heatsinks have all been removed, the regulator has been replaced with a modern switchmode model, and the KERNAL ROM has been swapped with a modern EEPROM adapter carrying my modified ROM routines. I finally remembered to snap a good overview photo of the inside of this hotrodded VIC-20.
