From a software view this is almost
identical to the standard 6502. The differences include
some memory-mapped I/O registers for an on-chip 6-bit I/O
port, and a slight variation of the unofficial op-codes.
Like the Atari's version of the 6502, the 6510 also had a
signal (aec) to tri-state the bus which allowed video
processors to take over. Onhttp://www.funet.fi/pub/cbm/,
you can find the
6502/6510
instruction set as well as the
Illegal
opcodes.
