HP Classic Series Display Driver

[Harald]

I am really impressed by what Bernhard (Panamatik) and Tony(teenix) have done.
I especially liked that it is possible to transform a wookstock calculator into any modle you like with Bernhards newACT. And I thought it would be nice to have a similar solution for the classics, but Tony's hardware and software (teenix.org) can't drive the original display drivers.
So I started a little project myself and go some results. Here is a little teaser:



Tony has been really helpfull providing a software for the PIC that scans a 5x8 rather then his usual 6x6 keyboard layout. Now once we get the display data sent from his controller to my controller, all I need to do is design a PCB and we have a drop in replacement board for the classic series main boards.

But don't hold your breath, there is still some work to do...

Cheers,
Harald
