I'm currently collecting about every tech data I can find on MSX,
and putting it in an Excel sheet with links (which can be converted of
course). Instead of just putting all textfiles together, I want to combine
it and filter out double info. Kind of like Ralf Browns interrupt list for
MSX.
If I have anything ready I will put it on my MSX page (but this
may take a while)
