Heh, I remember they had a friday-night trivia contest at the
mid-90s students pub (for natural sciences) where one of the
questions was the opcode for 6502 LDA (or was it NOP?), and I
believe I got it right. The opcode for NOP is burned into my
memory as $EA was used for erasing code during debugging in a
monitor. And it was also the letters for the big game company
Electronic Arts...
The cycle counts for 6502 are pretty easy though as they tend
to be related to the addressing mode and most of them are in
the range 1-5... No instruction for multiplication or
division... Oh the fun...
2-7 cycles ;-)
