David Collins of the HP Computer Museum and I just recently completed 
reading some 200+ paper tapes from the museum collection.  He used a 2748 
coupled with a custom Arduino-based interface to produce plain-text files 
containing an octal representation of the tape bytes.  We passed these 
through a small program to convert them to binary files and a second 
program to verify checksums of those tapes containing relocatable or 
absolute binary object data.  The resulting files can be used as is with 
the HP 2100 SIMH simulator or could be punched back into physical paper 
tapes if desired.
