Just a final question. If I connect the Amiga to a CRT monitor and use a VGA compatible resolution (like multiscan) and get a normal display that would pretty much rule out Lisa, right?

@Jope
On a 200m DCV setting I get the following readings:

IOR > AR -00,2
IOG > AG -00,7
IOB > AB -00,1
Here it says that these pins can have between 0 - 0,7V (peak value) depending on the intensity.

The LISA pins are TTL outputs so:

By choosing the correct background colours on a single colour screen you should be able to detect HIGH and LOW on all signals.
