Microsoft BASIC for 6502 is the original assembly-language source code for Microsoft’s BASIC interpreter version 1.1, written for the MOS Technology 6502 8-bit microprocessor back in the late 1970s. It was used on pioneering personal computers (such as the Apple II, Commodore PET, etc.), enabling users to write and run programs in BASIC on those systems. The repo contains the full source (in 6502 assembly), with support for multiple hardware platforms via conditionals, includes floating-point arithmetic, string handling, arrays, math functions, I/O, etc. ...

...A PIC24EP running at 70MIPS has emulates a 65C02 running at about 6Mhz. The example code configuration uses a copy of the BBC BASIC ROM image and a simulation of enough of the Acorn MOS to make the BASIC work using a serial UART connection.

Another NES emulator is a fun project. Goal of this project is to learn how to program an emulator and to get a deep understanding of the MOS 6502 processor.

yaMOS stands for: yet another "My Operating System". This is a hobby Operating System, let's see to what it develops... At the moment it's only a kernel written in C++ and Assemly.

SarcASM is a high-level, two-pass assembler mainly aimed at fostering development on archaic and embedded hardware. Though it will initially be a MOS 6502 assembler, other architectures are planned as being supported.

An Operating System that is used for storing data like a database. The best way to communicate with the system is over network.

Ursine Core is/was a simple RPG-type game development library/toolkit for the Atari Video Computer System (VCS) model 2600. (That's the 1977 Atari game console.) This library is intended to be portable to other MOS-65xx-based computers (6507, 6502, 6510, 2A03, 8502), and introducing support for other systems is ongoing (Commodore VIC-20, 64, 16/+4, 128; Apple ][; Nintendo Entertainment System) Ursine Core is a developer's suite hosted on a POSIX-like workstation. The Ursine Core provides: * converters for PNG graphics into tile, font, and sprite artwork for the various platforms * converters for MIDI and (soon) waveform audio into sound effects or music * string conversions and font support * tile-based "walk about" map mode ("overhead view") * "storybook" screens with bitmap graphics * simple text-driven menus * a custom language for writing scripts, that compiles into efficient machine code Note that this project is GPL, but games produced by it need no
