RE: BASIC for the CBM-II/8088

Hallo allemaal,

As I said before, I learn something in the process as well. 

I also found out that I used direct screen accesses for doing my own scrolling. Reading a character using INT 10h and writing it to the next or previous line would take even longer than 2 seconds IMHO. But having seen Michał's CBM-II in action, I knew I had something wrong. Studying some INT 10h documents I noticed some routines for scrolling. One could be even used to clear the screen according its documentation. And yes indeed, it works like a charm! It is less faster than the direct access method but better than I expected.
