    I just remembered a device from about 1976 that may help you read the 
tapes without gunking up your ASR-33:  the Oliver Engineering OP-80 paper 
tape reader.  It uses optical sensing only, and the tape does not touch 
anything important.  Here's a article showing how to build one easily:

    Besides, your old tapes are likely going to be pretty soft after using 
the solvents on them.  The ASR-33 reader pins are likely to go right through 
the paper and mis-read.  That won't be a problem with this optical reader.
