HP97 The journey begins

[teenix]

Hi all,

I have populated the new boards.

I changed a few pin assignments on the processor so I will double check that the software matches then I will program it and try it out. I modified the display driver slightly as the LEDs were a tiny bit too dull. This display, like the Spice board, can be user set to Bright or Dim when in use.

As you might see, the interconnects between the display and print-head boards are using the original HP board connectors. There is no room for ribbon cables and no substitute for these that I can find. If the original boards are not functioning anymore, then these pins may as well be put to good use. It is not hard to solder them, you just have to make sure they are aligned properly which is easy to do.

If anyone wants a new board and doesn't trust their soldering, the pins can easily be de-soldered and mailed to me, and I will fit them.

Enough for today though :-)

cheers

Tony
