This is the original 6502 cpu core. It was replaced by "MOS 6502X".

It's pretty decent. It does its job well.. it wasnt ever validated for the nitty gritty details:
|
||
|
|
1. spurious memory accesses
|
||
|
|
2. fine details of irq timing
|
||
|
|
3. others?
|
||
|
|
Moreover, this runs instructions one at a time instead of 6502X's one cycle at a time (several iterations for one cpu instruction)

|
|
Therefore, this core might be useful for something where the accuracy doesnt matter that much but more speed is warranted.
