I've had this 15C since it was brand new (about 1985) and now its on the fritz.
The problems started about 2 days ago, it intermittently responded to key strokes. Then the screen just went blank and now it doesn't respond at all.
I've tried replacing the batteries without success. (I WILL try another set of new batteries.)
Any ideas on where to get it repaired? I'm in NYC.
Is it worth anything to collectors as it is?
I love this calculator; for some features, its easier to use than the 48G I have.
I've checked eBay and they're going for about $155., usually in unknown condition. So it sounds like a repair might be less.
Suggestions would be appreciated.
Thanks in advance.
