I was cleaning the head on one of my 9-track drives and used a tape that
I've had around for while to check my work. It's labeled VAX-11 FORTRAN
FORT046.A and seems to be backup tape for VAX FORTRAN 4.0. Total length
is only about 750KB.
Anyone interested in the contents before I scratch the tape?

Yes, please don't scratch the tape before recovering the contents.
Regards
Rob

Okay, I can even do a bit more--my dump was a straight-to-file, ignoring
filemarks, so, for example, it starts with the VOL1 header. If you can
describe the layout of a VMS backup tape file, I'll be happy to re-read
the tape and segment off the stuff between filemarks.
Might as well learn something in the process.

Wouldn't it be best to read it into a .TAP file format if you are
going do anything with it?
Are you using your PCTD16 controller or something else to read the tape?

I would agree, .tap file format certainly works for me.

Yes, the PCTD16. Just using the raw TapeOut funciton.

I have a real mode MS-DOS program I wrote to read a physical tape into
a .TAP file using the PCTD16. I'll have to find a copy of it if you
are interested.

Sure--otherwise I can use mine that simply creates a new file for tape
date between filemarks.
