I would be grateful if someone on this list could help me. I have a somewhat old-fashioned colleague who still uses an HP-85B. This morning he came and asked me why the paper advance on the built in printer wasn't working, what was he doing wrong? He had borrowed an old HP-85 from another section (who had thrown it out, apparently - it had a red sticker saying "Equipment not to be used"), but this also wouldn't advance the paper, so he had concluded he must be getting something wrong. I tried a couple of times to no avail, so I took the lid off. (Why do they have to make the tape eject button so huge?). Not much poking around to discover that the toothed belt that drives the paper advance had perished and snapped. The rubber was mostly in dust all over the place; the strengthening threads were wrapped around the drive gear on the motor. The smaller toothed belt that drove the print head was also very ropy. So, we opened up the other 85. The same fault, with the remaining belt in worse condition. To conclude, then, does anyone know where to get replacement belts, or what the HP part numbers are, or any other useful information?
