Right before I got into computers for real, I was really into building electronic projects of all sorts. I lived in the local Radio Shack store.
I had a 50-in-1 electronic kit which I really abused. But what I *really* wanted was the new 150-in-1 kit from Radio Shack. I mean, I *really* wanted it!! I was probably 10 or 11 at the time. IIRC, it even had a 555 timer or some other small chip on it.
But for that holiday season, instead, my dad got me this:

When I showed my disappointment that I didn't want a "ELECTRONIC DIGITAL COMPUTER" and what I really wanted (and I really thought I was going to get) was the 150-in-1 kit... he took it away as quickly as he gave it to me. Rightfully so, as I was being an ungrateful brat.
But he eventually gave it back to me after "I learned my lesson". So a few days later I sat down and tried to figure it out. Nothing about it was "electronic" or "digital" or "computer". It was a set of levers that moved up and down, and you connected them with wires that eventually lit up incandescent bulbs in the "display". Inside the display you were supposed to put these tissue-like-paper sheets with PRE-PRINTED letters or numbers inside each box. Based on how you wired up the switches and lights, some of the boxes would light up. It really didn't do anything to teach about computers, logic, or programming. It was an exercise in placing the wires based on the instructions, inserting the proper "display cards" and moving some levers to get the pre-defined results. REALLY BOOOOORING! It could not do anything like on the box -- "predicting the weather"?? "computerized medicine" WTAF? Looking back on it, one can see how it might have been able to create a set of AND or OR gates and to be able to light up the lights based on that.. but a "DIGITAL COMPUTER" it was not. I played with it for about a week, and realized it was pointless and boring. I was now even more disappointed that I didn't get the 150-in-1 kit.
If my dad wanted to introduce me to computers and programming, one of those CARDIAC kits for $10 probably would have been 1000x better that this dud (sorry, Dad!).
Here's a video of the thing in "action"
