Well, I am now really close to having a mag tape drive working on
a Linux system. The docs confused me, so the bit ordering is
backwards. That will be easy to fix. It is not detecting file marks,
they just show up as zero-length records. I'll have to track that
down.
What I will do next is write a program that reads in a whole
tape to a disk file that is an exact representation of the tape.
So, there would be a 32-bit record indicator that would be 1-65536
for a block of data, -1 for a file mark, and -2, etc. for various
errors.
it's capable of getting PDP-4/7 DECSYS fortran compiler running ? if
not, I can agree with Al on the redundacy....
