Bah, of course, the Atari was a PC w/ a 68000, so you needed to do
everything with the CPU, so you had to optimize *duck* :-)

Hey now, I didn't claim it was an optimized solution :) I was just illustrating
Marcus'
bswap explanation and similarity with m68K :) This said, I thought movep stored
bytes noncontiguously or something ? (an instruction I never recall using on the
amiga, but which was most useful on the ST with the fscked-up interleaved
bitplanes words and such? :)
