Quite a can of worms. Most CRT's are electrically the same. Then
you have to have a good fit. Beyond that games probably went
from common consumer jugs to higher resolution CRT's & actual computer
monitors. Differences were many but in most cases unimportant.
We used to have a CRT spec chart that decoded MODERN CRT numbers
but I have looked on the internet & didnt find it.
Old US & jap style numbers were easier.
Getting rid of the dead wood "legally" is also an issue. to do it right it
will cost you $$$ like $20 - $30 each......
