I posted a similar request some time ago. The response was that they were once available (educalc?) but those who still had them were going to hold onto them. I don't know if HP made any.
I think they could easily be made using the type of prototyping PCB tool my company has. This is like a mini milling machine with an x-y head. Once the 'layout' of the overlay is entered a sheet of plastic could be cut to the required shape. Our machine is used all the time so the chance of me getting to it are slim :-(
PS - can anyone think of the reason the hp49g has a USER function? (Appart from being a hang over from the HP48G) Without the ability to have keyboard overlays the owner has to remember what each USER key does!

I've bought them from the late EduCalc in the previous century. I just wanted the transparant with the math/greek symbols on them. But it was a package of math/greek symbols, 3 creme and 3 transparent. One creme I did cut up so it would fit a 42. So I have 2 creme and 3 transparent for sale or trade (also a HP82143A printer). I would like someone to help me on a 32/128Kb ramcard for the 48.
