My pragmatic approach to switch between BASIC and FORTH. Because it is switched not so often a simple jumper with a resistor does the job to switch the A13 between high and low.

I really like #Forth. But on the #MicroProfessor #MPF1P it is very difficult to enter, because of the small display size. But tons faster as the #Basic of them. It remains on my todo list to make a video about.
For all which are interested, I made two short videos about the MPF1P on our channel (English subtitels)
