Father’s Day tribute, Thanks Dad, Atari 400

Oh boy, just looking at the picture above gives me goose bumps! This is the system that started it all. The Atari 400 home computer system.  It had 4 controller slots, a cartridge slot and a membrane keyboard.   Playing Pacman, Donkey Kong and Q-bert on this unit felt like playing it in the arcade.  Most importantly, it was my first exposure to programming via the BASIC language. We would get manuals and write up test programs. Great learning experience for us in our youth.

I also enjoyed the box art of the games. You can tell that they spent a good amount of money and time at the time to create a masterpiece on the cover of the boxes.  That is more than what I can say about a few of the games that are released these days.  I was not impressed with my last two purchases, Street Fighter IV and Punchout’s box art was pretty awful in my opinion.

A year or so later, we picked our first tape drive or program recorder. The Atari 410..

We would buy games in cassette tape format and play them on the Atari 400. It was our first disk drive if you will. It was mostly used for recording computer programs that one would write utilizing the BASIC language. The Atari 400 did not have a big enough hard drive to satisfy the recording required.   This is the system that introduced the PerezStart.com Family into technology. All of us have chosen to work in a technology related field and we have this system to thank. It opened up our imagination and motivated us to pursue the interest of computers at a very young age. I remember my dad telling me that he purchased this unit with a Christmas bonus he received from his job. Thanks dad not only thinking of your children, but for selecting a “computer” for christmas. You planted the seed for your children’s future!

Which computer system did you own in the 80′s? Do you still have the unit stored away in your closet?

    Just came across your site. My 400 has been in 24×7 use for the last 15 years and I'm amazed that it's still going strong! It runs a basic program which interfaces with some hardware to send control signals around the house mains wiring. The signals are picked up by receivers which switch relays to turn mains appliances on and off in accordance with the program.
