        # PiISA / PiGUS

![PiISA Logo](piisa-logo.svg)

### *NOTE*: this repo no longer contains the PicoGUS project for the Raspberry Pi Pico. It has been moved to [https://github.com/polpo/picogus](https://github.com/polpo/picogus)! ###

ISA card emulation on the Raspberry Pi 3, 4, and CM4. Initially focusing on [Gravis Ultrasound (GUS)](https://en.wikipedia.org/wiki/Gravis_Ultrasound) sound card emulation.

This is a work in progress in the experimentation phase. It can emulate a GUS and produce sound but things are nowhere near perfect! Please see [the Wiki](https://github.com/polpo/pigus/wiki) for current status.

## For "big" Raspberry Pi:
