	This account contains BIGTPC which is used to make copies of 
the sig tape.  BIGTPC can copy DOS,BRU, and DSC formatted tapes.
First one uses BIGTPC to read a master tape into a big disk file.
The file is as long as there are blocks on the tape.  Then one uses
BIGTPC to read that file and copy it back to a blank tape.  The bugs
in BIGTPC where it would hang up at the end are fixed.  
To read a master tape onto a disk one uses the following command line:

	RUN BIGTPC
	TPC> DN:RSXSP81.BRU=MT:
 
To make a copy of the file onto a blank tape one uses the following command
line:
 
	RUN BIGTPC
	TPC> MT:=DN:RSXSP81.BRU
 
The only problem I know of with BIGTPC is that if you install it and use it
as follows:
 
	TPC DN:RSXSP81.BRU=MT:
 
It will work, but the file RSXSP81.BRU will be in directory [0,0].
