Scalable OS for 6502/65816
With great embarrassment I have to admit never having owned a 65xx computer... but suport for these classic machines shouldn't be difficult to add -- for instance, I have declared as 'reserved' the two first zero-page bytes in case the utterly popular Commodore-64 (using a 6510) is targeted.
Back to my own-designed devices, here's the range (past, present and future):
