There is a detailed description of the circuit with the PAL colour card (it's on the euro //e motherboard) in Understanding the Apple //e by Sather (see archive.org for a copy) on pages 8-16 -> 8-19.

You do get the green/purple fringes on text, the euro //e has a switch on the motherboard that turns off the TCA650 and forces mono mode which is handy for 80 column work.

I _suspect_ you don't get all of the NTSC artifacts since PAL will be a bit better, but I really need to get my TV plugged in on my //e running one of the games (adventures typically) that use artifiacts to check.

The other alternative is the apple authorised ITT2020 which added an extra bit to the display so shows "jail bars" on screen when running ][ software. Again I should drag mine out to do some testing.
