Calculator displays

[andylithia]

One year before, I discovered this backlit LCD module.
With minor modification to my HP-10b (which is in a pioneer series chassis), this module can substitute the original LCD almost perfectly (The new module is a little bit narrower, requiring some black tape to hide the edges).

One downside is that the PPI and resolution combination is not very suitable for the opening on a pioneer(or at least on the 10b), which means the texts are gonna be either too small or too big (2X) if one is planning to emulate an HP-42s display.

The controller IC on it is UC1604c. I don't know if there's any international seller of this module out there. I'd like to help if anyone is willing to use this module.
