I should have said that the tape image contains a number of data files - which I can process - but I need to extract each individual files first. I did do this a while ago using tapecopy or tcopy or mt or something-or-other...

extract a tape dump in SimH format

​Can you be a little more detailed here. The file is a SimH format of the a tape. But the tape itself has been formatted by the application on the OS that wrote it.

eg. if its a UNIX "dump" format tape you need: something to under the SimH format and create a bytes stream to push into a program that understand the UNIX restore format - which also means you might have NUXI issues depend on the simulator that wrote it, since dump writes integers in native formats in the metadata.

or if it's a TOPS "dumper" (aka backup)​ you will need something to under the SimH format and create a bytes stream to feed program that understand the PDP-10 dumper format.

FYI: I used to have tools for the later part, although I have never run them on Linux. The last time i ran them was an Alpha under Tru64. I'll have to go digging.
