   The HP-41 card reader recognized a 67/97 card and automatically
translated it to 41 code. Some of the 67/97 instructions didn't exist
in the standard 41, but were insteadimplemented in the card reader.
Like operations on the `I' register, which I think became card reader
XROMs that operated on register 25. Pretty neat.

(No clue as to whether 41 cards will work on 67/97s.)
