It's amazing to me how people can go on for days about completely
off-topic stuff like whether or not LCDs give people headaches, but
completely ignore thread(s) about trying to fix classic gear.
Most, if not all, people here respond only to posts when they feel they
know something about the subject. In the case of repairs, you'll only
(alas) get comments if somebody else has that particular machine (or at
least has read the servivce manual/printset).
If this refers to your RM02 problems, I didn't reply because I have never
worked on a Massbus interface, I don;t have the prints, and so on.
