Greetings.
I am interested in writing an emulator for some old computer. However, I’d like to pick something simple for a start, some architecture that is not too complicated and relatively well-known, so that its easy to find documentation. Could you suggest something?
Also welcome: links to technical specs/documentation of the suggested platform, rom archives, etc. 🙂
The good old Commodore 64 would be a good choice. Well-documented, lots of ROM archives available, and a fair amount of community support available.
It runs on on 8-bit microprocessor (the MOS 6510) which operates a RISC instruction set and should be fairly straightforward to simulate (in as much as any hardware emulation can be called “simple” 🙂
The processor datasheet is even available!
