Oric1js project was a learning project to see if I could build an emulator for a computer I own when I was a kid : the Oric 1.
The main intention was to learn how to build a VM. I started with an emulation of the 6502 emulator, then I added emulation for the 6522 and the 8912 for emulating just enough to get to the Oric 1 prompt and be able to type commands.
Rem 1 : The keyboard is emulated so you can type a few commands. However, the ctrl key is replaced by the left alt key because ctrl shortcuts will usually trigger shortcuts on Windows.
Rem 2 : The emulator is a bit slow, so I increased the IRQ frequence by 10 so that typing on keyboard be snappier.
Rem 3 : The ROM is included in the source for convenience but of course is not covered by the license.
