It was my lecturer's uncertainty in the indirect modes of addressing
that meant that my first year micro project at university was to get a
Commodore Pet to calculate 2**3000 (every digit).  I loved the 6502 with
(what I'd consider to be) its semi-risc architecture: 3 internal
registers (AXY), 256 (pairable) external "registers" (zero page),
syncronous memory accessing, pipelining (resulting in small number of
clock cycles per instruction)...oh such memories...
