I have "re-visited" making this board many times onver the past few years. In fact the PCB artwork is about 95% drawn up.
Every time I crunch the numbers and look around I find that there are still DOZENS of genuine originals available often for well under $100 so it just doesn't make sense for me to reproduce something that is still very commonly available in original form. I can't understand why RD would make these at all???
Because a LOT of people haven't got a clue on how to repair the existing boards, small issue = replace the board
That's why you see original boards for sale in the first place
