hello, fellow 6502 lovers
Some of you folks will be interested in this project. It is a co-processor that extends the 65c02 architecture, and it provides new registers and new instructions that are fully as fast and flexible as those of the legacy CPU. One of the main benefits is a 16 MByte address space, implemented without the constricting "window" arrangement that's the mainstay of ordinary memory expansion schemes.
I hope you enjoy the article! All feedback (and questions, especially if anything stated is unclear) are welcome.
Cheers,
Jeff
