[Simh] TU-58 tape

[Don North]

My mistake ... after checking the website these look to be block by block image 
of TU-58 tapes, but labeled as '.tap' files instead of '.dsk' files.
The .dsk file would normally be a block for block image of the disk (or block 
addressable tape) device.
Whereas a '.tap' file would not only have data, but embedded flag words for 
record separators, end of file indicators, and such.

So as Mark indicates these files should be mountable on the SIMH TU58 device and 
accessible by the appropriate software (ie, VMS TU58 driver in this case).

The console devices on the VAX750 and VAX730 simulators can boot from bootable media (device TD as I recall).  All simulators have simulated TU58s connected via simulated DL serial ports with the device known as TDC.  Up to 32 TU58 drives are supported.
