Multiple Kernels #1. The extra leads are for the DualSID.
A couple of years ago I put together my “Ultimate Commodore 64” with multiple kernels, dual SID chips for stereo sound, reset button, USB, Ethernet, a 16GB flash drive, 4 Joystick Ports, and painted blue! You can get more details from my presentation at World of Commodore 2011. However, I accidentally killed the motherboard recently when messing around with my RN-XV Wifi project (oops). So, a swap was in order.
I bought a fully socketed 64C motherboard from eBay and swapped it in with the appropriate chips, then re-applied all the mods I had made. One thing I’ve done differently this time around is to use clip leads instead of soldering to my shiny “new” motherboard. I’ve documented the internals in pictures, it turned out pretty cool and is hopefully useful for documenting the top-side connection locations.

very long ago I put a lot of mods in my flat C=128. I put a video on Youtube about it a wile ago Here: https://youtu.be/RZU6Iyybm_8 The RAM in it is the one I used to save the real time Q-Link data long ago.
