Screen Shots

The Electric Company Math Fun a simple math problem-solving game. It was kind of fun sometimes when I was a kid. OK, not really. Math Fun also underwent a ROM revision. According to the Intellivision Lives site, the original game had you enter answers in "pencil and paper" order, which seemed backwards, e.g. 4,1,enter for 14. After revision, you supplied answers in "natural" order, e.g. 1,4,enter for 14. I've only noticed the "pencil & paper" order in Learning Fun I by INTV and the Intellivision, Inc. copies of Math Fun.




ROM Two versions of the ROM exist.
Box So far, seven variations have been found.
Manual Fourteen variants have been identified.
Overlays Four different overlay variations are known to exist.
Label To date, five labels have been recorded.
Easter Eggs No Easter Eggs have been found.




A total of seven The Electric Company Math Fun box variants have been documented.

The allegedly older version of this ROM has you enter answers in "pencil and paper" order, while the later versions have you enter in "natural" order. I've personally only seen the pencil-n-paper order on the Learning Fun I cartridge and on the Intellivision, Inc. version in "modern" times.

I swear we had the backwards entry version when I was a kid, but sadly that cart no longer functions. It could also be that my parents exchanged it as defective as well. I do recall it was one of the five carts we got when we got the Inty for Christmas in 1980. (Let's see, those were Baseball, Football, Math Fun, Space Battle, and, of course, Poker & Blackjack.) I haven't checked the part numbers on the chips of my other copies to see if they're different. All I can say is that the white label version appears to have the 'backwards' entry ROM, but rev. G1 instructions - which are NOT correct for that ROM!

Supplemental Materials

The following supplemental materials have been found for The Electric Company Math Fun.

Image Vendor Part Number Year Origin Description
The Electric Company Math Fun Additional Materials (Mattel Electronics) Mattel Electronics N/A None   Correction to instructions, step 6 on page 8 to use 'backwards' entry; discovered this in a copy of the PlayCable manual for Math Fun—has anyone found this thing in standard copies?

It's surprising how many revisions there are for this 'edutainment' title. The original (not pictured, not sure if it exists) and revisions A-D and G1, which just had updates of the replacement overlay order form. The existence of the original (not an "A" version or later) is assumed, provided that the purported ROM change truly did happen when the Intellivision Lives site claims that it did. Interestingly, the two copies of the Intellivision, Inc. version of Math Fun that have passed through my hands both have the 'backwards' ROM, and have instructions based on rev. G1 of the manual. I've only seen revs. A, D, and G1, and all of these describe answer entry in the 'natural' order - i.e. 3,4,6 for 346 - NOT 6,4,3, which is what the 'backward' ROM requires of you. So, if anyone has a copy of the manual that describes 'backwards' entry (around p. 9 or so) - please send scans!

There were also some variations of the 'Running Man' and Mattel logo on the back cover.

Running Man Logo and Text on Back (rev. A (U.S.A.))

Title Screen The theme to The Electric Company blared when you reset the game. Unusual for the early games—and not really particularly well-done, honestly.
Number Jungle Gorillas jogging by the riverbank, leaping over other animals. Erm.... OK. Edutainment still hasn't really caught on. Wonder why?
