Raw Blame History

Commodore PET

a computer from 1977 which was leader on US schools back then. subsequently the Apple II took its throne.

maybe no better than a computer terminal, but somebody discovered a way to update the screen at turbo rate - and eventually its sound "chip" (it was nothing more than an 8-bit shift register) was abused as well.

some of these didn't even have sound...

effects

  • 10xx: set waveform.
    • xx is a bitmask.

info

this chip uses the PET instrument editor.
