Funny, I seemed to find all 8 local registers usable. And all 8 input
registers unless you needed the values. Likewise all 8 output registers
were usable unless you call a function. So I make that 16-24 depending
on circumstance. And if you're not interfacing to C then you've got 6 of
the global registers available anywhere, as you say.

I find that better than ARM, and 68k. As for intel, well that's a laugh.
Never programmed MIPS or the other risc chips.

Of course, the 256 registers on the 6502 are much missed(*).

Cheers,

Martin.
