|
| I learned a lot.

| Great video and usually i love Ben's work, but, @ 7:48 he

| Ahhh i see. So technicallyyyyy it's a 65C02. All good.
|
| So if you're trying this code on an original 6502 it will not
| work, but easily modifiable to use the X or Y registers
| instead of A.

| All the CMOS variants have it, regardless of manufacturer.
| The manufacturer-specific instructions are:
|
| - RMB/SMB/BBR/BBS - Rockwell/later WDC only
|
| - WAI/STP - later WDC only
