I know this is an old post, but I wanted to add my question into the correct post/forum, so hopefully I've done that, if not, I apologize. I’m looking to learn more about this Atari 2600 that was given to me.
Atari 2600
Property of Atari Inc. Sunnyvale, CA 94086
Manufactured: 1977
Manufactured by: TRW Electronic Components Company In Taiwan
Model: CX-2600
Box: Copyright Atari, Inc. 1978
Light or Heavy Sixer: Not sure? (looks like a light)
I have a question (or maybe questions) about my Atari 2600 (CX-2600) that was given to me several weeks ago. A friend of mine passed away in 2007 (age 38) due to a chronic disease that he had all his life, and I've kept in contact with his Mom for the past 6 years. She learned (from my e-mail signature) that I liked Atari. She asked if I wanted her son's (Charley) Atari 2600, because it had been sitting in the closet for 25+ years. I said yes.
She sent the Atari 2600 with the original box (Copyright Atari, Inc. 1978), but the motherboard and switchboard both read copyright logo © 1977. She said they got it for Charley the first Christmas that the Atari came out, so why would the box read 1978, unless it was made in late 1977 and they got it for him for Christmas 1978?
I opened the console and took it apart to clean the inside. I was shocked to see that it was spotless. The inside cover of the Atari console was a bit dusty, but other than that, it looks and works great.
The switchboard and main motherboard both read © 1977 (pictured), but 3 out of 4 chips (4th has no date on it) read 8108, 8120, and 8121, which I thought that meant the year (1981) and the 8th, 20th, and 21st weeks of that year. I noticed the piece of paper taped to the top of the EMI shield cover reads the letter Z (it could be 2), and also the date (in red) July 13th 1981.
From what I've gathered from the enclosed photos (with detail), my friend received his Atari 2600 in 1978 (made in 1977), but... had it worked on in July of 1981. Something must have happened to where they had to replace 3 out of the 4 chips inside the console. They didn't have to replace anything (chips) on the switchboard, just the main motherboard. I could be incorrect about my assumption(s). None of the boards have been replaced.
Does this all mean they had it repaired in 1981?
Why does the box read 1978 when it was built in 1977, unless it was built in late 1977?
Is this Atari 2600 a Heavy Sixer? It looks more like a light sixer.
I noted which chips were replaced. I apologize for the flashlight, but I wanted to note the dates perfectly.
Thank you for your help.
