1. GBS 8220 does not accept an Amiga signal on the VGA port like it is supposed to. It rudely blocks the Amiga 15.75Khz signal from the VGA port.
2. It forces you to connect your beautiful Amiga picture to EGA/CGA which I was told blocks the 16.7 million colors of the Amiga.
I would happily buy one if it didn't seem to be junk.
It might be ok only for A500.
