First off let me say the forums here are amazing. The depth of knowledge carried here is second to none. Hence Why I signed up.
Very recently I decided to start into the hobby of collecting vintage Atari games and systems. I started off with a modest purchase that included 2- cx2600A's, 4 joysticks, 4 pong paddles, all required RCA's and power cables, and 91 carts. Many are duplicates, some with subtle differences, (i.e. text vs. pic etc.)
I was using the rarity guide as a benchmark for my purchases to see what I got and what common/uncommon/rare is going to do as far as my ability to get more carts. I have a cart here in front of me, titled Blueprint. It is a white case with yellow writing on it and was liscensed by CBS Electronics. It did not show up in the rarity guide. I noticed that several people in the forum have seen/heard of said title and was curious as to its rarity and so on. I don't plan on Ebay'ing it in any event, since I bought these all for me.
I also have a Dig Dug cart, that was listed as a #2 common, I believe. Once difference between mine and the one listed, ( it is a silver label) the one listed in the rarity guide has a publish date of 1987. Mine hasa publish date of 1983. These were not listed on the guide at all, so I am curious to that one as well.
There are other questions I have as there are probably 50-60 carts I have yet to go through, but I will leave it to these two for now.
Thanks to anyone that can shed light on the situation.
