HP 39gs to newRPL - Keyboard Overlay?

[Martin Hepperle]

Recently, I acquired two new HP 39gs (I could not resist the 4€ sales offer).
After playing with its limited HP 38G-like language and variable handling I think I have to convert it to newRPL.

NewRPL seems to be the best way to make better use of the HP 39gs keyboard and display, even if its RAM may be a bit small.

The main problem is the different keyboard layout. Are there any keyboard stickers available? Do they stay on these small keys?

I have converted for my own use some HP-20b and 30b into WP34S, but I never mad the stickers myself.
There seems to be little information about suitable printers and which material works best.
I see these small Cricut cutter machines which seem to be the right tool for cutting these stickers.
What are the alternative options?
