Re: Z80 <--> 8502

Hello

I guess it's not all ins and outs but I found two helpful sources:

1) manual for Double-Ass - a well commented switch routine is at the very
end of the document:
https://www.zimmers.net/anonftp/pub/cbm/c128/programming/d-ass.txt
2) this post that links to other documents
https://intoinside.github.io/2023/07/07/running-z80/
