Hello TeoZ,
I think the commodore 128 had a digital output that
went to a 9 pin
connection and probably would make a mess connected to a analog 9 pin cga
input.
I think monochrome, and CGA were TTL on 9-pin connectors
I know EGA was TTL on 9-pin.
VGA ( analog ) was output on 9-pin in some instances, but either later
on, or more commonly, on HD15
Best Regards

Most pc cables are idiot proof, its when your connecting a non PC (or older
almost PC compatible) to a PC monitor that you have to be carefull. I hate
companies like tandy that switched wires on their "standard" cables so you
HAD to buy their version.
Even if they do mate correctly you have to worry about 15khz outputs (amiga,
atari st, c64 etc) that dont sync on modern 30+Khz monitors without some
kind of help in between.
