Re: CBM-II Character Set and Colour Expansion

Hi,
Yes, I just completed the fix and it works. The main difference is the character sets. On the B128 the 8x8 set is fairly basic and the 8th column is generally blank. On the high-profile (HP) machines the 8x14 font is more detailed (serifs) and so many characters have pixels in the 8th column. With the "fix" the 8th column is repeated making some of those characters a bit weird looking. I think I'm gonna have to tweak the HP character set a bit ;-)
Now I'm off to fix the reversed bits.

Haven't tried, but since the schematic od the video circuitry is
identical, there's no reason why it wouldn't work on a high-profile :-)
