[PANAMATIK]

If there were single digit, 7 segment LED's available, I may be able to affect a repair with my skills. Doing the tiny soldering several times over is probably going to end up badly for me!

As it is, I have a personal machine. When there is no decimal point displayed, I know it is after the first digit!

When considering using my display solution you will get back all digits, but you will have slightly smaller digits and they have a minimal different look than the originals. If you like to find a donor display you can use any woodstock model from HP-21 to HP-29C, all have the same display. However you should try to get a non working non repairable model, otherwise you transfer the display problem just from one calculator to another.

Good luck
