About a year and a half ago I decided that I needed a custom overlay for an application on my 48GX. I first contacted hp to see it they still sold the blank overlay kit that James described, which they of course did not. HP Calculator Support could not even provide me with dimensions or any details about the overlays. (At this time, they still sold the GX, mind you.) They referred me to SMI (who I believe makes the TDS Cogo cards), stating that they make overlays for their products and might be able to give me dimensions or other help. So I contacted SMI, they were very helpful. They sold me three of their overlays (customized for their application) at a very reasonable price, and gave me the name of the company that actually produced the overlays for them. I used the overlays I got from TDS as the basis to produce a bitmap graphic of my custom overlay. I also contacted the company that produced the overlays for TDS. The were also very helpful, but as I suspected, they were not in a position to produce one or two overlays for a single user. They were set up to supply many overlays for a commercial enterprise. Costs would have been in excess of $1000 for 50, I only needed one or two. So I gave up on that plan and perfected the graphic image of my overlay. I found it was possible to produce pretty good looking overlay images on plastic transparency material in a color laser printer in the exact size, but never found a good way to cut out the overlay and keyholes. I also tried painting over the overlays I got from SMI to create a blank, and running them through a laser printer, but that didnít work either. My next step, which I have not gotten around to doing, will be to contact local printers and/or label makers and/or sign makers to see if they can produce them for me. Perhaps one of them will have the CNC equipment James mentioned and will be able to do it easily.
The above story is of course little help to you, sorry. About all I could offer would be to e-mail a bitmap image of a blank overlay that you could use to design yours in case you could find somebody to produce them for you. Let me know and I will send the image.
