Hello Everybody,
I started with the 48SX back in the early 90's (my pride and joy at University).... and then I got the 48GX ..... and then the 49G ..... then the 49G+ ..... along the way I picked up Sparcom libraries and expansion memory for the ports of the 48
One by one all the screens turned black ..... I made a video and put it on Youtube... but nobody came up with a solution.
However, I am not completely destitute ..... as I have two 50G calculators that I bought while they were still selling new on Amazon ..... over the years I have grown to love these (even though it took me a while to recover from the loss of my 48's )
The two most important features that define why I will never want any other brand of calculator are the RPN entry ..... and the user keyboard, where I have keys programmed to do all the original functions that had a dedicated key (switching the display between Polar and Rectangular being the most used of those)
I have lost other monochrome LCD devices also..... must be the temperature and humidity of the tropics ?.... has anybody else experienced this ?
and yet there are screens that have survived..... I have a Yamaha keyboard from the 80's (being the oldest example)
I never had the heart to throw out the hp calculators ..... because they were all working perfectly before the screens went black...... usually an oval patch that just expands and expands outward until nothing can be seen
Any hope ? ..... Anybody want them ?
Best Wishes,
Stephen Mendes
