HP-01 available

First Light!

The first new HP-01 prototype board is running!

As far as I can see the design concept will be still OK. The board does not yet fit inside the HP-01 case, because the prototype board is too thick, but the next prototype will have reduced PCB thickness of only 1 mm and need some other modifications too, but I will come nearer to the aim of the project. The solder resist will become white in the final version.

What I can show, and you can see in the images below, is the prototype board with processor chip and real time clock and the original HP-01 LED display mounted on top. The LED display multiplexer is running already.



As astronomers say to their new telescope, it gets first light, I can say now, it emits first light.



The emulation of the original microcode will follow next week. It is already running on a woodstock calculator
