# 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 output, leaving the user to solder in a speaker on their own...
|
|
|
|
## effects
|
|
|
|
- `10xx`: **set waveform.**
|
|
- `xx` is a bitmask representing a pattern of on-off pulses. it has nothing to do with wavetable assets, which can't be used by the PET.

|
## info
|
|
|
|
this chip uses the [PET](../4-instrument/pet.md) instrument editor.
