IBM Record Unit....

[Ron Hudson]

I had a passing though of writing emulators for the
machines found in an old record unit shop,

Card Punches - would be something like an editor.

Sorters, Collators?, and all the other machines, with
text files as card-decks.

I have the link on Wikipeadea, it also just gives a
gloss overview. I am not finding the detail needed.

Never mind, it wasn't important. I'll go on to other
things.
