awesome series.

[@thomasfriedrich2001]

Thank you! Inspired me to write an emulator. VIC-20 works meanwhile. PET is more work, for it does a lot of HW diagnosis and requires deeper logic of peripheral controllers. In restropect, I estimate proper function tests as you have done consequently!

Good work!

Dave, take care: lsb is bit 0, not 1. We have bit 0 to bit 7.

Yeah, pretty sure i noticed that and changed it later (perhaps not this episode though).
