It isn't it's own ISA for a few reasons, but basically the CPU is a regular device model. It's running the kernal (they spell it with an a) ROM, and the basic ROM. I've mostly implemented the board logic and have started on the graphics, but then there's audio, interface devices, and then a mechanism for cartridge, disk, or cassette based program loading. It's a very simple computer from a modern perspective, but it still has a lot of parts. I've been ignoring timing mode for the time being. I would actually rather not check it into the main repository since that puts it more in the middle of things than it deserves or is warranted, but I thought it might be amusing/educational/interesting for other people that want to play with it.
