The VGA scrollback buffer is limited by the text area of the video RAM. The text area is in the DOS memory at 0xB800 (or 0xB000) and extends 32 KB (or in case of MDA, 4 KB). Each character will use 2 Bytes. Therefore you can store up to 16,000 characters or 4 pages of text. -- Ich danke GMX dafür, die Verwendung meiner Adressen mittels per SPF verbreiteten Lügen zu sabotieren.
