Upload with MiniPro?

I have a handful of AT89S52 chips here, and a TL866 II-Plus programmer. Is there a way to create a custom “board” that is just the microcontroller itself and set MiniPro as the upload protocol?

I don’t see that chip being supported in directly. If it’s a generic Intel 8051 variant you might have luck basing a new board off as base, using sdcc as the compiler (docs). You would however also need to teach the platform the new upload program (idk what you use for uploading) via a custom upload protocol, as there’s only stcgal support (docs) .

So the good news is, I am about 40% of the way there. Not knowing what I am doing is a slight hinderance, but hacking up some MiniPro support will probably be quite advantageous. I will attempt tp submit what I create when I am done.
