Re: Tesla Programmer
I was thinking possibly of removing (or not fitting) everything east of the 8255 and instead controlling the 8255 with a current microcontroller PCB like an Arduino or a Raspberry Pi. (level shifting would be required for the latter, yes, but its in-built mass storage / file system would make the creation, management and selection of programming files so much easier).
The availability of a PCB does make this a more appealing prospect.
