I've got a 7 track tape here that was written on a
PDP-10 TENEX setup.
It's identified as a "mini-dump" tape. I can extract the data (PDP-10
5 char/word) successfully, but the format of the block headers (seems to
be about 6 words) eludes me. I'd like to be able to use the original
file names. Does anyone have information on the mini-dump structure?
Yes. I wrote this by combining various documents, MINI-DUMPER and
DUMPER sources, and testing. It includes both MINI-DUMPER and DUMPER.

I wrote a program to read and write such tapes:

I haven't tested extracting a MINI-DUMPER tape, because I don't have any
samples. I have created tape images, and tested reading them from
inside TENEX.
