These projects will only work with Acorn's RiscPC, preferably fitted with a user port. They can certainly be adapted to work with other machines, but you will have to do your own programming. None of these programs will work on an Apple or a Windows machine.

I designed most of them to try and make my computer science and low level programming classes a bit more interesting. They all work well and come with programs that are presented as open source so that you can easily pick up the essentials.
