PDP-1 emulator, running on Raspberry Pi Pico, written in Rust. See my tweet to know how it looks like.
This repository contains a KiCAD project, schematics and gerber data, for the DAC to covert X/Y CRT position in 10-bits ditial to analog signals so that oscilloscopes can show picture in the XY mode.
Also, you can find a firmware under the firmware directory. It is written in
Rust, and you may need some setup to build it. This document doesn't explain
details (because I remember only partial setups...).
The project expects VS Code with some Extensions to develop ARM based processors with openocd.
- Speed control: now the emulation core counts cycles, but doesn't synchronized with real timer. So, it runs a little faster than the original PDP-1.
- Game controller: yes, I know what I should do, but didn't implement it yet. See my TODO comment in pdp1.rs's IOT instruction handling.
- Snowflake support: PDP-1 emulation core may have a bug around ALU as the snowflake shows broken images. I have a working C++ version. So, it can be fixed soon.
- Rust readability: as I'm new to Rust, the code still doesn't look so nice.
- Documents: agreed...
CATS: ALL YOUR PR ARE WELCOMED TO US.
