At least TPC files are slightly more portable than some
formats (RSX-11M+
Virtual Tape comes to mind).
Now if only there were some magic to keep a TK50/TK70/TZ30 drive working
for more than ten minutes. And by "working", I mean anything that doesn't
require disassembly of the drive and the computer to free a jammed tape.
Actually reading the bits is more than I could hope for :-)
