And for real high-speed "paper" tape, you could use mylar tape instead. It was much more durable and you could really zip right through it. Only problem was you had to be *real* careful what punch you used to make the tape. It turns out that a lot of punches relied on a little bit of oil in the paper to lubricate the punch pins. The mylar tape, not having any oil of course, would cause the punch head to get *real* hot and eventually fail. We used it to contain the standard bootstrap for some Microdata 1600 minicomputers used as communications concentrators. It usually wasn't necessary since the Microdatas had core memory, which was non-volitile. For our remote sites without an ASR-33 to boot from, we would just send out a (core) memory board, they'd plug it in, and come right up running the software we last loaded into it. Ah, the good old days. Computing with stone knives and bear-skins. louie
