Default Re: Gemini 80-Bus System

Thanks - It got the program and the same effect as yours. Problem is it performs
an unlisted escape sequence ESC 8. Why? I cannot find any documentation
that mentions this code. On a real SVC card with version 4.1 software it appears
to be ignored. The next 1a byte clears the screen - having already output the copyright message, again strange.

On the emulator this takes the next character and uses it as the font height for the
screen mode. That is why you see a taller font which you said was double spacing.
This is an extra escape code added by me.

I need to work on a option switch to sort out this incompatability.
