I have been blessed with *two* Teletype ASR-33's. Apart from a minor cleaning, they are going to be just fine. EXCEPT the rubber platens are as hard as Chinese arithmetic! In case you havent experienced this, if the platen gets hard, the printer doesnt print well-- the typehead kinda bounces off the paper and doesnt leave a clean dark mark. I've tried the usual remedies-- acetone cleans them up, but they're still rock hard. I need some suggestions! Should I try ArmorAll (known to soften rubber, given time), "Platen cleaner", "belt dressing", "french dressing", or what? Note that I don't need to clean or make it "grippier", it needs to be softened, a lot. Regards, George
