The 6502 was the CPU in my first computer (an Apple.
#6502 emulator mac upgrade
Jergen posts about a re-implementation of the classic 65C02 microprocessor, found in many classic computers, in an FPGA, in a pin-compatible format that lets you upgrade those old computers and games to a 100 MHz clock rate.
Even with all the documentation on the internet, I still struggled with it. The 1 microprocessor FPGA Emulation VintageComputing. I think that the only thing hard to understand are all the different addressing modes of the 6502. It is a much simpler processor than the 8080 and it looked like it might be easy to emulate.ģ 8-bit general purpose registers A, X, and YĨ-bit stack pointer (fixed at RAM address $100, so can address $100-$1ff)ġ48 total instructions, (a lot of these are the very similar) I started looking at the 6502 a little bit. The VS64 extension comes with a built-in 6502 CPU emulator that. The VCS used the 6502 processor which was also used in all these machines:Ītari arcade games including Astroids, Battlezone, Missle Command A latency-hating emulator of 8- and 16-bit platforms: the Acorn Electron, Amstrad CPC, Apple II/II+/IIe and early Macintosh, Atari 2600 and ST, ColecoVision, Commodore Vic-20, MSX 1, Oric 1/Atmos, Sega Master System and Sinclair. Emulator 101 8080 reference 6502 reference 6502 EmulatorĪ couple of weeks ago I read the book Racing the Beam which is a great book that combines a history of the Atari VCS (the Atari 2600) with technical details about how programmers struggled writing code to work on the primitive Atari VCS hardware. Free and open source 6502 code projects including engines, APIs, generators, and tools.
