Not meaning to throw things to far off but on my
NC4000 machine( 16 bit ), I found ByteSwap useful enough that I had it

I have an old computer that was intended to do FFTs. It has a
complete bit order swap, MSB to LSB, instruction.
All interesting.

9-track tapes on the PDP-10 used one of the following
encodings:
What about 7-track, any idea? I would assume 6 x 6-bit tape frames per 36-bit
word, but that's just a guess.
