50 years ago, ASCII (USASCII) wasn't terribly common, except on 7-level
TTY.  A lot of machines used 6-bit codes and IBM's new line of S/360
used EBCDIC.

But I think I've run exactly one emulation on SIMH--IBM 1620--and it
didn't involve tape.

I chose the SIMH .TAP format because it was formally documented.  I
include a copy of the document with every tape job.
