If anyone is interested, I have code for a Linux
SCSI tape to
AWSTAPE program, and a program that translates aws format to a raw
byte stream. Not sure if I have one that translates to the SimH .tap
format, though. GNU C.
I've got a Linux utility to translate SIMH .tap to raw binary, if that's
interesting to anyone. I would have thought that such utilities existed already.
