between the election and a sinus-migrane, i didn't do anything tonight really. ;)
i did look at some avr-usb related projects. some imteresting stuff being done there. i kind of came up with a super-cheap Atari 800 drive->usb adapter in my head - I'll call it the SIOsimple USB. ;)
My next step is to put an order together for a batch of ATMega85's and support parts to wire them up as USB... and then get to wire-wrapping!
