Paper tapes+rubber bands+30 yrs = mess

I have a large collection of paper tapes that came with a vintage Altair 680b and Teletype model 33 that I inherited. I've restored the machines and have started looking at the tapes. Unfortunately, I have discovered that the rubber bands that were used to keep the tapes rolled up have all dissolved into a yucky gooey mess that is in most cases, stuck to the tapes. I'm pretty sure the oil on the tapes and 30+ yrs time have done this dirty deed. Sadly, there were original, unopened MITS Altair editor/assembler tapes, BASIC, etc. still sealed in their original packaging but the rubber bands inside have melted all over the tapes. Has anyone dealt with this kind of cleanup before? What are my best options for solvents to get rid of what's left of the rubber without damaging the tapes too much more? What a mess. Parents, talk to your children about rubber bands... Chris -- Chris Elmquist mailto:chrise at pobox.com
