I found this programmer on the net, that I wish to give a try.
Single sided PCB, soldering iron, that seems within reach of my hobby
capabilities. Later as my knowledge and confidence grows, I may
try programming through FPGA and PICL directly.
What I need to find out yet, how to best match the PIC to FPGA
frequency. PIC has got its own xtal, and may support also low cost RC

I was also thinking to use PIC as a single loop PID controller,
Oberon then as a sort of supervision and visual layer for trends and
some optimisations. Not sure though, we could do PID without FPU math,
just using integers?
