Posting Pictures of my Test Market sets
Hi Everyone
Here is the inside of Serial number 2411. I have lower serial numbers and will show them later.
If you look close you will see all 1985 date codes on the chips and also there is even one chip on the board that dates
from 1984.
Thanks

I have notice a lot of people talking about having their early great NES consoles with the letters
TM after entertainment.
Please take a look at the test market sets you do not see the letters TM after entertainment.
TM was Nintendo trade mark but I believe it did not take place till much later units.
Anyways I am not sure of the exact date Nintendo started placing TM on their consoles but you will never see a test market unit with those
letters on it.
Thanks
