I've pulled together details of the controller

The details are at this link..

The unit and Arduino code are both pretty rough and ready and I'm sure can
be improved - but they served their purpose!
Hope it is of use to others...
Now to get those new tape files published...

Papertape Reader for Archiving Tapes
Further to Dave?s post below, I?m happy to share the Arduino code and
schematic if anyone has a suitable reader and wants to try it. It was
indeed designed to interface to the HP2748 but is pretty simple and could
be adapted to any similar reader.

I have the s100 board Jon Chapman (glitch) created to interface with his HP
2100 reader. Not sure if anyone here woukd have use for it.
Anyone use the Decitek 2910 or HS1000 portsble model (you can buy from
decitek.com) for archiving 1 inch papertapes? The 2910's are available
new, they come with older windows/ DOS software, memory buffer, rs232
port, slows to 110b.
For the volume of tapes I have, getting something new is appealing for
reliabikity-sake.

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.
