I just wanted to report my satisfaction with a temporary overlay that finally makes my newly flashed calc fully useful to me, until such time as version 3 bugs are worked thru and Eric resumes making his vinyl overlays for the new version.
Though I am still on 2.2, the version 3 manual briefly includes instructions on how to size and print the overlay provided with the Sourceforge download. I happen to be be most comfortable with Photoshop, and setting the overlay width to 68 mm provides a ppi of just under 595 without resampling the image. In Photoshop, I create a new 8.5x11 doc with that ppi, and cut and paste the resized overlay image four times onto the new document. I make sure there is a wide margin all around as when I tried to fit six overlays on one sheet forcing printing at 100% cut off the edges due to the intrinsic printable area for my printer. (In printing on my Mac, it seems the default is to shrink things slightly to fit, so I must force 100% in order to maintain the correct 68 mm width.)
I then print on pretty good quality paper, cut out, and just stick over the keypad with double-sided tape. I don't bother with flaps because the key feel is just fine through the paper. I use a monochrome laser printer and find B&W works fine for me since the correct shift key can be quickly discerned from placement on or under the key. If I like this arrangement for a more than temporary fix I may splurge a few dollars and get colour laser printing done.
This a great calculator and I love it more each day, so I just wanted to share how delighted I am that I found such a simple way to make it easy to use. It isn't cosmetically perfect, but it is functionally just great. I have a 15C LE, but it goes neglected as I become fascinated with this wonderful gizmo.
