Digi-Comp 1 — The First Home Computer
When I was a kid, it bothered me that most people were more interested in the ads in comic books than in the stories. Most of what was sold was junk, of course — the notorious X-Ray Specs for example — but once in a while a legitimately interesting product was offered. So, in acknowledgment of that, here’s an ad from a 1967 Marvel comic book. It’s the Digi-Comp 1! Click to enlarge.
If not exactly the first home computer, the Digi-Comp 1 was a working binary counting machine. Here’s a Digi-Comp 1 in action, counting from 0 to 7 in binary. It’s even done twice, in case you miss it the first time. 
Exciting, huh? But compared to the comic book ad the Digi-Comp 1 must have been a disappointment. First, there’s nothing electronic about it, and the atomic symbol would seem to imply it’s nuclear in some way. But at least the Digi-Comp 1 is described accurately as being a “mechanical analog of a binary computer.”
I hope the person who wrote the ad copy didn’t use a Digi-Comp 1 to figure out the price, because it’s listed first at $4.99, then in the coupon at $4.98. Oh well, they didn’t claim “down to the penny precision!”
The Digi-Comp 1 has, as you might expect, something of a cult following. Original units are often auctioned in eBay, and there is a replica of it made today out of wood, instead of plastic, available at Minds on Toys.
