6502 rdy pin
Does a 6502 have a FPGA?
[Jürgen] then packaged that core in a Spartan-6 FPGA and placed it on a small PCB the size of the original 65C02’s 40-pin dual inline package. We’ve seen the opposite before too, with a real 6502 paired with a FPGA acting as the rest of the computer.
What is a 65C02 RDY line?
This article describes a generic schematics for the generation of the RDY line used by the 65C02 processor to hold bus accesses when the device is not ready. You think this is not necessary nowadays, where everything is way faster than the one or two MHz the 6502 runs at.
Where can I find 6502 code examples?
Scott Alfter hosts the entire archive of Apple Assembly Line , an old Apple II publication with a lot of good general 6502 content. wiki which contains both general 6502 code examples and material specific to the C64 and other Commodore machines. MicroChess is a very famous game written by Peter Jennings in 1976.
