newRPL - Updated to build 1510 [official build remains at 1487]

[spiff72]

If anyone is interested, I may be offering overlays for sale for the 50g (I already have this one done), and soon for the 39gs. I may look to see if the same overlay can work for some of the other compatible calcs in the future, but I will work on the 39gs first (since I own one).

See this thread for more info:

I am attaching a pic of my 50g with the overlay installed.

The only thing I am waiting on is to confirm that the new vinyl material I use as the base layer will stick better than the recent ones I used. (The key labels had a tendency to lift for some of the non-RPL calcs like WP31S/34S.) I just got some new material and installed overlays on all the calcs and I am waiting to see if the adhesive is performing to my satisfaction.

I will be posting updates in that thread as I move forward!

Thanks!
