I was wondering if there's a pcb for the analogue board with 4851. I tried to make it myself with Kicad, but woah.. after a couple of hours yesterday trying to build the tracks with pcbnew I almost smashed my mouse on the wall..


If no, do you have any hint on how to build the analogue board? Is the easiest way is to build the old pcb and solder a wire instead of the resistor without connecting the bat85 tracks?

I guess I could build it on those mounting plate (plastic board with cooper "holes"), but a picture of the "design" would be much appreciated to get me started.


Any help is welcome.. Thanks!

You can use the available Analogue board PCB design with 4851. Just don't solder BAT85 diodes and replace input protection resistors with jumpers.

Is there a mistake in the complete component list on the website? Two 1N4148 diodes are used in the keyboard control schematic; in the list, however, only one is said to be required.

Download the PDF files with all the schematics, you will find the associated components list there (for both analogue and digital boards).

Because it doesn't need a PCB.
