    Chris;

    What is your objective with this project:  reading the data or 
preserving the tapes?

    For the data, I would first check around and see if it's already 
available.  Contact me off-list and I can put you in touch with a number of 
6800 sources.  As you probably know, it is possible to read punched tapes by 
examining them visually and retyping the data.  The data is arranged in "S1" 
records that have a checksum at the end of each line, which will help in 
catching mistakes.

    For the old tapes themselves, I would recommend a product derived from 
orange peels called De-Solv-it.  It's readily available at Walmart and many 
other sources.  See www.orange-sol.com for the fascinating background of 
this company.
