I think this is even more true with video games since the early years of video game history are largely unknown and unexplored and people often make or repeat such claims without examining the evidence (which often doesn't exist).
Today, I examine a couple of these claims.
The First Video Game With A Microprocessor
The first is the question of the first video game to use a microprocessor. The standard answer has always been Midway's Gun Fight and that may well be true. In one of my first posts, I examined the idea that PMC's Aztec might have beaten them to the punch but it turns out it didn't.
Today I look at another candidate that has much more solid evidence behind it. - Mirco's PT-109
An article on Mirco in the November, 1975 issue of Play Meter had this to say:
The article here is talking about the 1975 MOA show in October - the same show where Midway debuted Gun Fight. Note that Mirco is the same company that introduced Spirit of '76 - generally considered the first microprocessor pin to be released (though I have my doubts about that one as well - there were actually at least two more microprocessor pins at the 1975 MOA).
And if you didn't know, Spirit of '76 was designed by Dave Nutting and Jeff Frederiksen who went to Mirco after Bally rejected their microprocessor pin prototype in 1974.
Here's the second page of the PT-109 flyer.
Note that it claims the game is "microcomputer controlled".
While PT-109 was on display at the MOA, that doesn't tell us when it was actually released. The game's release was announced in the November, 1975 issue of Cash Box, though I don't have the issue handy to check the verbiage and they may have just been announcing that it was on display at the show (though some companies actually started taking orders for their games at the MOA).
I would like to confirm that PT-109 had a microprocessor and if so, what kind, but It looks like it at least came out very close to Gun Fight if not at the same time.
In my earlier post, I mentioned another candidate for first microprocessor game - Jerry Lawson's Demolition Derby. Exactly when the game was created is unclear. Lawson says he started in 1972 or 1973 and either Goldberg or Vendel (I think - I forget which one and don't have my notes handy) report that Alcorn told them about Lawson paying them a visit during their Pong days. Demolition Derby used a Fairchild F-8 microprocessor but likely didn't have one until 1975, when the processor was released (though as a Fairchild employee, Lawson could have gotten a preproduction version).
Lawson supposedly sold his game to Major Manufacturers, who tested it but never released it, but I have not been able to confirm that fact. I did find the following interesting comment in the October, 1975 Play Meter however.
Once again, the subject is the upcoming MOA show. The article mentions that Major would be showing two "arcade games" and the wording makes it sound like they are not talking about video games, but is it possible that one of the games was Destruction Derby?
Finally, there was this mutant from the 1975 MOA that I discussed in an earlier post:
I don't know if this had a microprocessor, but given that it had a central unit that controlled multiple remote terminals, I'm guessing that it did. Of course, I don't know if it was coin-operated. (though it WAS on display at the MOA). The March, 1976 RePlay reported that the manufacturer (California On-line Computer Systems) was working on a "super machine" that would probably require an attendant rather than taking coins or bills and planned to show it at the California State Fair in August.
First Japanese Video Game - First Game With Human Figures
Another potential first involves another obscure game - Midway's TV Basketball
The October 15, 1986 RePlay made the following claim.
According to this, TV Basketball was the first licensed Japanese video game to be released in the US (a title that is sometimes awarded to Taito's Speed Race, which Midway released around February, 1975 as Wheels.
Of course, this article says that the game was licensed to Atari, which makes the claim a bit questionable. Did they first license it to Atari, are they talking about a different game, or did they just get it wrong.
Here's a blurb from the April 15, 1986 issue
