The color Killer is working strangely on my machine....
when the machine looks "idle" it's working I have a black and white screen
but as soon as I use the floppy disk (for example command: "catalog")
the caracters are colored with strange patterns mostly blueish / redish...
when the floppy stops I get back the black and white
I slighlty reduced the value of the resistor, the problem partly disappereared
but still exist while using the floppy disk
(before it was present each time I was using an extension board like the language board
or a legend memory board
any idea on how to fix that
thanks to all
