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.
