Hi Eric,

Thank you for your help.  I've had a look at your utilities
link and I'm going to give them a try.  

Best,

 It's John Wilson's tape image file format.

 A data record consists of a four byte record length, the data,
 then another copy of the record length.  The record length is stored
 in little-endian byte order.

 A tape mark is fourbytes of zeros.

 There are no extra padding bytes to force any alignment.

 Bob Subnik's SIMH tape image file format is similar except that it
 uses 16-bit alignment.  SIMH comes with utilities to convert the
 formats.

 There are also some simple tape image utilities at:
