Hi Chris,

Please go ahead, I would have posted them myself, but there was no room in my account.

Also, I may have missed it, but could you please post the default program that the calculator ships with for 25C and 33C?

Is it the same for both e.g. arcsin(arccos(arctan(tan(cos(sin(9­))))))?

Quote:Did you friction fit them on different inclinations before fixing them? Is there a lot of differences w/ the angles? Honestly I did not plan attention to this before.

Yes, I friction fit and tried different angles. For table top use and with the calculator flat, you may wish to have 30 degrees. If the ICs are socketed, the calculator is sloped, so 20 degrees seems to work well. For handheld use, zero degrees might be best as the keyboard is so compact.

Cheers,
