user13896: I used to play Video Chess on Atari with my dad when I was a kid.  What is the approximate FIDE rating of each level?

user20721: Atari 2600 has bugs which make the higher levels unrateable. It is reputed to be slightly better than Microchess, according to a chess.com article.
Atari had a very limited book which makes it weaker than current approaches. 
An ESTIMATE of the strength is as follows:
Level Time Rating(?):
8        10       700
1        15       800
2        30      1000
3        45      1100
4       165      1300
5       195      1350
6       720        ??
7     36000        ??
