  Contribution #1 by Entunassa:
  
  I´m not very experienced into MPP trackers and not into programming also. We have to check different concepts or existing schematics for what we can use.

  (this is one of the finds from "the internet"...)
  

  I suggest a modern software approach that yet fits in a tiny PIC or ATMEL; my hope is to find a tiny program which maybe can be translated to the 4004 system without pushing its boundaries.

  It could help not to re-invent the wheel, but rather have the focus on the conversion to the 4004.

  Let´s face some ideas about the hardware. What do we need, what has to be covered?

  • a minimal solution is preferred;
  • using vintage parts (?);
  • converting an existing schematic (?)
  • power saving by switching-off electrical parts when not needed (?)
  • simple status indicator
  • ... (to be continued)
