Followup on my travails with the Highway 100 converter:

By default, Roger Johnstone's IIgs --> SCART cable applies composite sync to 
the composite video input on the converter.  MdntTrain told me this yielded 
the best results on his unit, so I never really mucked around with it.  Today 
I discovered that I'm better off applying the IIgs composite video signal to 
that pin!  It seems to have solved the worst of the banding problems and the 
picture now looks quite good.

The question is: Why does this behave so differently between the two 
converters?  At any rate, life is now good and I can heartily recommend the 
Highway converter to other IIgs owners with the proviso that you may need to 
do some experimentation with the wiring.
