Tar files are simply streams of bytes.  They are NOT simh tape files with built 
in record sizes and tape marks.  There may be tools to convert a tar file to a 
simh structured tape, but I personally don't know of one.  It wouldn't be too 
hard to write a program to do that though.  The simh tape structure is 
documented in section A.3 of http://simh.trailing-edge.com/pdf/simh_doc.pdf

If you use the latest simh code from 
https://github.com/simh/simh/archive/master.zip and you happen to have 2 
network interfaces on your Linux Mint host machine you can easily get 
networking working.  If have two NICs I can walk you through the details.  
Alternatively, bridged networking can be setup, but the details are 
significantly more complicated...
