Re: 17B mk 2 - how to open case? Message #4 Posted by Paul Brogger on 9 May 2003, 7:12 p.m., in response to message #3 by Dave Brown
You don't want to try removing the key. The Pioneer calculator case front and keys are all molded as a single plastic unit. Each key is attached to the case by two thinner sections of the plastic, which act as hinges. To remove a key, you'd have to cut the hinge.
You may still want to do the water soak before opening the thing. It could be that the mylar dome is held down by something sticky, and not actually damaged.
Randy Sloyer just fixed a stuck R/S key on an HP-42s of mine with several baths in an ultrasonic cleaner. (It turned out that, for that one, I think he had to use a solvent to remove machine oil or something, but water should help with anything that's water-soluble.)
If you do need internal keyboard spare parts, those from any other Pioneer model should do. Here again, I think Randy has the details.
Good luck, and keep us posted.
