I assumed it was a look-at-screen-and-retype instead of a cut'n'paste
job; because JGH's HADFS suggests a much greater familiarity with the
6502/MOS than to do a mistake like setting X to 255, and *then* to the
value of the stack pointer...
That said, I find I have to look in my book to confirm which way around
TSX/TXS go - for being used to the ARM where the destination comes first...
Best wishes,
Rick.
