Cartridge: Early signs of life

February 4, 2012 -

The cartridge is slowly, but surely, taking shape. I'm simultaneously designing a PCB which I will have etched once the cartridge seems to work fine. Right now, I'm working with something that looks like this:more

Away with the breadboard

...and enter the 8-bit baby. Not much soldering done today, but I've got the ISP connector and a dual power up and running. I.e. the cartridge runs whether it's connected to the C64, or the STK board.more

Ok, now we're talking...

I'm almost where I left off with the previous cartridge project. I've got the micro controller hooked up on the C64's bus, and it's respectful enough to let the C64 run flawlessly as if it's not there.more

SID parts

January 17, 2012 -

I soldered the first ATmega88 onto a DIP adapter board today, in order to start breadboarding up the SwinSID chip. I've got the 20MHz crystals and a couple of TDA1543's as well, even though I think I'll try to manage with a R2R DAC instead. I didn't get as much done as I wanted to, but I'll get there eventually.more
