The standard tape reels had a capacity of 260 feet of tape. Standard tape thickness was 1.25 mil, so it would have theoretically been possible to put more tape on a reel if you made it thinner (which was hard to do because thinner tape was typically also stretchier). Making the reel larger wasn't a good option because the hubs on the drives were too close ...

The fascinating thing to me is the way in which the media is a hybrid of a punched card and a floppy. It's more like a floppy - especially in its original version, the IBM 2321 Data Cell Drive of 1964 (see below). MagCards are a downscale from the 2321, which was, at its time the top end of random accessible online storage. They provide much larger storage ...

(Credit goes to @tofro for the answer) The actual command to activate ftape is: $ sudo modprobe zftape This loads both zftape and ftape, and creates all the necessary devices under /dev, so there's no need to run MAKEDEV.

You most likely wrote your early experimental programs in the BASIC language, using Timex’s ROM-resident BASIC interpreter and line editor. Cassette-tape storage would have been accessed using the SAVE and LOAD commands in the interpreter’s immediate mode. Commercial software, however, would nearly always get written in machine language — to gain the best ...

I'm not sure why you're calling it a "hybrid" — it clearly has nothing in common with a punched card, other than the approximate shape and size of the card, which may have been chosen to take advantage of the storage facilities that already existed for punched cards. It is clear from the video that there is a pair of counter-rotating drive wheels, ...
