A
close relative of the
6502, the
6510 is the
CPU inside of the
Commodore 64. It has
3 registers,
256 opcodes (although not
all of them are
useful), and runs at
around
1 MHz, depending on wether it's in a
PAL or
NTSC system. I'll
spare you the
opcode list I
thought of
pasting here :).
Also related is the
8500, which is used in the
C128, and is
2MHz capable.
