As I recall, Pong was $99 I beleave?
Can't remember what the 2600 was? $149.95? Nor the NES, but when the genny took the price drop down to $269 I bit Then Sony took the Playstation down to $199 and the $179 shortly there after
and I bit on that
Anyways, $80 back 1975-1980 does not = 200 now LOL! more like 10-15X the dallor of today.
You could buy a house in the 10,000 to 25,000 range back in 1975. *shivers*
