Odd "endianness" [was Re: RE: Base 64 posts to the list]

[dwight]

Not meaning to throw things to far off but on my

NC4000 machine( 16 bit ), I found ByteSwap useful enough that I had it

hard wired.

I have an old computer that was intended to do FFTs. It has a

complete bit order swap, MSB to LSB, instruction.

All interesting.

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.
