the second mod was to remove the RF modulator and hooked it bypassing the tuner on the TV for better picture, and i could then also simulate different monitor colors, amber (yellow), green, black on white and reverse.

i also ended up getting a 16K expansion.

that's the one i learned my programming skills, when i got bored of the limitations, that's when i switched to a IIe clone (could not afford a real one)
