Those of us of a certain age can remember this.

For those of you who don't want to click through, Mr. Wizard takes apart an Atari 1200XL to show what is inside. Then goes to disassemble an Atari joystick to show what is inside that. Now I remember this episode fairly clearly. It inspired my 5/6 year old self to go into my dad's workshop, dig out a #2 Phillips screwdriver take apart my Atari joystick, which I did successfully put back together. I think I did also try to play a game just pushing the membrane buttons on the circuit board.

And for those paying extra attention will note the Vectrex in the background.

Thanks for the view boost...

I actually sourced the ep and edited the segment out after someone here mentioned it a year or 2 ago.

No problem. It just showed up in my recommended videos feed this morning -- watch one Mr. Wizard video and a whole bunch of retro gaming stuff = your vid.

IDK if you already have it up on YouTube but I do remember a later episode where he is showing of MSFS2, I am almost 100% he is running it on an IBM PCJr.

I remember that segment very well. I was already into the Atari 800 computers, so I recognized the 1200XL immediately even though I hadn't seen that particular model before. I think this was the first time I had ever seen a computer opened and explained in this way, and I always remember it whenever I explain computer architecture to my students today.

I'd highly recommend the entire Mr. Wizard's World DVD collection. I picked up all eight volumes earlier this year. I don't believe they include every episode ever filmed, which is too bad, but they did manage to include lots of segments featuring classic computers. Besides the 1200XL segment, I remember a demonstration of a Vectrex light pen, a demonstration of Logo on an IBM PC, and a few segments featuring a TRS-80 Model 12 running some simple BASIC programs and an old word processor from Microsoft called Scriptsit. There were also a few shows which featured a Heathkit HERO 1 robot.

Can't view youtube from where I'm at currently; is this the video where he identifies the RAM chips as the system's eight bits?

Thanks for sharing that. That is a series of shows I never got to see as a kid. I think I need to do some YT digging for Mr. Wizard!

P.S. I think he lost the fire button spring.
