By the way, this raises a question: Is the ADAM computer in Europe PAL as well?
I have personally NEVER seen or heard of a CBS European PAL version of the STAND-ALONE ADAM COMPUTER WITH THE COLECOVISION built-in. The only ADAM Computer system that was sold in Europe that I know of was the Expansion Module #3 ADAM Computer which of course requires a ColecoVision to attach to and then uses the ColecoVision's RF output... so therefore the output is in PAL format.
Coleco or Coleco of Canada did release the Stand-Alone ADAM Computer (big blue lettered box) in Canada for the French market there (french language box, manuals, etc.) and PERHAPS some of these made their way across the ocean and were sold, but I highly doubt it due to a couple issues...
- The Power Supply in the printer would have had to be swapped out or converted, obviously.
- The video output would have had to be changed to PAL format, again, obviously.
I mean, if someone makes a fix for Defender, there should actually be two fixes, namely "NTSC + ADAM compatible" and "PAL + ADAM compatible".
Defender was fixed sometime around 1986 or 1987 by Jim Walters, a homebrew programmer back in the day for the ADAM, and the fixed rom image was made available to the ADAM Community on a self-booting Data Pack or Disk. My mail-order company would include this fixed Data Pack version with each Defender CIB that we sold... and we had a lot of them (probably 100) when I first started there.
This fixed rom version was later placed onto a cartridge by CBS Eletronics and sold by ADAM's House/eColeco and you can see a picture of the cartridge with the edited label below.
Parker Brothers did not release specific versions of their cartridges for the North American and European markets... only the box changed to support multiple languages.
To borrow a phrase from a famous movie, "This house is clean".
