Real music? Feh. Fun for five minutes. FORTRAN!!That's one language I've yet to learn. But I'm looking forward to it! You see, though...it's the music that I can awe other laypeople with ("They had computer music back in the early 70s?! Whoa..."). FORTRAN, not so much. :)Yeah they're pretty thin on the ground.

Darn. That'd be nice to have. I guess this system likely had one, or was simply using the interface to control the equipment. But I'd imagine someone was loading the program and such via the paper tape, and perhaps the other prototyping card was used for equipment control.
interface that would take some doing to duplicate with an SA800-interfaced drive.Darn again. Maybe that'll be a project down the road. I'm learning some FPGA architectures and might could practice my VHDL skills (not to mention analog data separators and what not) by making some converters. Of course, a microcontroller may be just as suited.

Magnetic tape drives are *physically* sequential-access, of course, but the
TU56 (for example) is logically a random-access, block-oriented device. (with
highly variable latency ;))
