This is an emulator for the 6502 microprocessor, which was dominant in the late '70s and early '80s.
This is but a Lua binding for Ian Piumarta's emulator, which is written in C (and is bundled here; you don't need to install it separately).
The use of Lua, a high-level "scripting" language, lets you easily build the "computer" around the processor using easy Lua code instead of C.
Using luarocks:
$ luarocks install lua-m6502
(Add --local (or prepend with sudo) if desired.)
Alternatively, clone the repository and do luarocks make.
-- Instantiate a microprocessor.
local mpu = require('M6502').new()
-- Write into memory, at address $600, a sample program.
mpu:pokes(0x600, "\169\007") -- "LDA #7" (loads 7 into the A register)
-- Set the program counter to $600.
mpu:pc(0x600)
-- Run!
mpu:run()
