Empty 9th character column - harware fix!

[Michau]

You can notice that in the text mode, there is always a 1-pixel space between characters. That causes unpleasant rendering of tables and other graphics characters. In graphics mode, the 9th column of each character is repeated after the 8th, so this does not occur.

To fix this, simply cut the pin #1 of chip U55 (on high profile machines, this is pin #13 of chip U83). This will make the 9th column also be repeated after the 8th in text mode.

Unfortunately, this makes the "m" and "w" characters to be displayed a little bit weirdly because they have some pixels in 8th column. This needs to be worked upon

Yes, this is documented on my CBM-II page. I made this fix long ago to my LP machine but only got around to documenting it recently. It seems strange commodore would mess up the graphics characters like that...

I must make this fix better by using an OR gate to feed this cut pi. Otherwise the "m" character looks ugly I will document this, but IEC cartridge first
