Wanted, Papertape Reader for Archiving Tapes

[dwight]

I've got a rebadged Remex someplace but it is intended for fan fold. It takes manual watching to deal with spooled tapes. It is a high speed optical with parallel. On spooled stuff, I'd set it up on a table with it hanging over the edge a little. Then I'd have a piece of scrap plywood as a separator for input and output piles. Being high speed, it can make a real mess if the output gets tangles with the input.

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.
