Difference in 0.2 and 0.1?

[DariBer]

I'm trying to find some info to see what the see what the differences are between v0.2 and v0.1 PCBs.

Mainly two changes: reset handling and enabling the mouse-trigger-option (setting variable voltage thresholds for reading the mouse x/y-values)

If I have 0.1 boards, would you recommend me to not use them and order 0.2 boards?

The only situation where you would experience differences is when you launch very old cartridge games (a handful, not many), which initialize the SID only once just a few cycles after reset. There's also a way to modify the 0.1 PCBs, but not sure it's worth it.

I wouldn't mind knowing how to modify the 0.1 PCBs as I am getting ready to build four for myself and a friend. I don't forsee either of us ever using the DAC so don't really want to order new boards. We will be running the audio straight through the C64 like you would with a vintage SID. I appreciate the info and the project!

There are two options:
1 (easiest when you build the SKpico): do not connect pin 30 of the Pico (e.g. leave pin out in the pin header), and on the SKpico-PCB you connect pin 29 and 30.

2 (easier when you don’t want 1, e.g. when it’s already built and soldered together): flip the diode as on the image and connect its anode to pin 29.
