Hmmm. I also found some docs about the rev 2 setup.
I'll try and dig-up the drivers for it. Perhaps I find my first SOS2000 too.
But it needs the MyIDE D700-D7FF RAM-modification to store data....
Ok, I found it all, except the source-code disk. So I really do not know
what bugs could surface. The driver uses the OS in RAM and replaces the int. char-set.
Not one of my best programming skills, but this first setup did work
Also some BASIC programs to check your home-brew interface.
