Do you have a list of the differences? I've never seen it documented.
I've never seen it documented, either. The first time I saw one, I didn't believe it. It was in a Dig Dug....I just figured someone hacked a Nintendo monitor into a Dig Dug. Then I noticed all the serial numbers matched...strange. I then thought Atari was using step-down transformers....no. The monitor is receiving 120VAC. I have since seen three of these stock in Atari machines. I didn't try to document it all....I just made a few notes of the obvious differences....The actual monitor circuit boards are the same....just different values of certain parts and part locations populated, that are usually empty
First, the metal monitor frame was stamped 20EZY....where it is usually stamped 20EZV....also, the flyback cage was stamped with EZY. This isn't fool-proof, as these parts can easily be swapped between the two.
Second, on the EZY...the inversion section is populated: R213/R214/215/R217/R218/R219/R201/R202/R203/C202/D210/TR201/TR202/TR203. These locations are empty on the Nintendo 20EZV. Now, this is not fool-proof either. Anyone CAN populate these parts on a Nintendo EZV (I have). Bob Roberts even sells a kit to do this.
Third, there's a handful of differences in the monitor's power supply section. The obvious one is the filter cap I mentioned...also, C601 and coil L601 were different. I'm sure there was more, but that is all I noted. Also, the cap kits are different.....
