[Simh] A basic question; can I mount tar files as tape devices?

[Michael Huff]

Hi

I have tried creating tar files and then mounting them as devices and/or 
reading from them with tar but I haven't had any success. I've tried 
googling and looking around, but I haven't figured out how to do this.

My host machine is Linux Mint/17/amd64 and I'm using the vax780 
simulator with 4.3BSD, and I'm trying to work out how to get files and 
and out of there (I haven't had any better luck with networking).

Any help would be appreciated --thank you!

Apologies in advance if I've missed something glaringly obvious.
