Once I have my PDP-11/03 working reliably with a SCSI card and SCSI2SD or something similar, maybe that would be a more convenient system for imaging the tapes, assuming RT11 can do what's necessary.
Sure. Reading the tape is simple. And then you have the tape blocks. The
question is what you do with them from there...
You might want to try and find some tool that creates some tape image.
Under RSX you'd normally use TPC, which creates file images of the tape,
which the same tool can then recreate the tapes from. The format would
be familiar to anyone who dealt with TPC-format tapes under Unix. ;-)
