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

We made it!

The C64 demo was finished at the party, several hours after the deadline. I didn't realize so much work remained; finishing the twist scroller, implementing the loader, adding and fading out the music, etc. I guess I spent about 12 hours coding at the party, in total. We were happy with the product, and landed on a 4th place in …more


Breadboard SID player (part deux)

I should be kept on a leash for my own safety, because I'm apparently quite stupid. I intentionally chose to avoid using RAM in this project, because I wanted a minimalist design with less wires, thus easier to debug. I also thought that the 6502 would work fine without RAM (which it theoretically does) since all the code is in …more
