Commodore 64

I was building a ROM switching adapter so that I could use modern 27256 ROMs in the 2332 and 2364 footprints on the Commodore 64. I decided to add an LED and resistor to the bottom for mood lighting. When I started adding LEDs of different colors it turned pretty sexy pretty fast.

The latest iteration of this adapted has the microcontroller right on the adapter under the 27256. It handles switching the address lines, choosing between 2332 and 2364, and runs the RESET and EXROM lines. I have a pin left that I could use to run a WS2812 programmable RGB LED.

The CIAs, 6510, and VIC are original. In this photo I have original BASIC, Kernel, and Character ROMs in stalled for testing but I normally use 25256 to 23xx adapters to use modern ROM chips with this motherboard. I bought the parts kit from Retro8BITshop and soldered it myself.
