Looking for 6502 simulator

[Eckhard Tikwinski <et@elmedgmbh.de>]

Long long ago I saw a very nice simulator for the 6502 processor
on an Apple II. I neither know the name nor where to find it.

The simulator displayed the internal datapaths of the processor
and, as far as I remember, animated arrows between the registers
during data transfers between accumulator and other registers.

Any help would be appreciated. Would be a good idea to mail any
answers to the email address below (remove the <nospam>).
