An advertisement showing the Mego 2-XL robot, several tapes, and a few of the board games that were released for it.
Status: Partially Found
The original Mego 2-XL was a children’s educational toy invented by Dr. Michael J. Freeman and released by Mego Corporation in 1978. The 2-XL was based on the educational robot known as Leachim, which Freeman had created for his wife Gail’s Bronx classroom. 
Leachim was six feet tall and contained a database full of trivia questions, which could be answered by pressing buttons on its chest. Leachim would then give feedback on the student’s answer, via the recorded voice of Dr. Freeman himself. Leachim served in the classroom from 1972 to 1975, by which point Dr. Freeman decided to work on a miniaturized version called “Little Leachim” and pitch it to Mego. This became the 2-XL.
The 2-XL worked by using standard 8-track tapes to hold the questions and feedback. As with Leachim, Dr. Freeman provided his voice. As with all 8-track tapes, the content was laid out into four different programs across the width of the tape. As the tape played, 2-XL would ask a question, and the player would need to press one of four buttons to respond. This switched between the different programs, which would contain responses to the different possible answers. In this way, the 2-XL “knew” what answer the player gave and could “respond” accordingly. 
The tapes were produced between 1978 and 1981, with Mego Corporation collapsing in 1983. A completely different version of 2-XL using standard compact cassette tapes was released in 1992 by Tiger.
The 8-track media used to contain the original Mego 2-XL programs has been obsolete since the early eighties. Like any magnetic media, they are also vulnerable to being wiped with a permanent magnet. The tapes have become collector’s items among 8-track collectors, Mego Corporation collectors, and vintage electronics collectors. Proper preservation requires playing the tapes through an 8-track player and synchronizing the audio between the four programs to line up 2-XL’s questions and feedback. Some tapes have been uploaded in this manner to the Internet Archive. Others have been preserved via the 2-XL simulator, which is a web-browser-based program for playing with a virtual 2-XL.
Most of the known releases are from the United States, as 2-XL fan-sites have compiled surviving magazine advertisements and mail-order forms. These show at least 45 confirmed tapes, a single planned tape that has been confirmed unproduced, and a selection of 18 with their release status unknown.  However, there were also at least four Spanish-language tapes released in Mexico by Ensueño Electronica and at least one French-language tape released in Canada by Grand Toys Ltd.

|Tri-Lex||Found||1979||This tape was used with a board game that you could play with 2-XL. Each game appears to last about 5 minutes, with 4 games used to fill the standard 20 minute track length. While all other 8-track tapes have only one metallic splice for switching tracks, this tape has a very strange configuration in which multiple splices are used at the end of each game. This is used because if a game ends early, 2-XL instructs the player to turn their audio down to zero until the next game begins, as any other audio in that game is irrelevant. This prevents the player from hearing the end-of-game music as well. However, the extra splice results in the player switching tracks with an audible mechanical "thunk", which is used to signal the start of a new game.||Lost||Found||Lost|

According to an advertisement from 1979, a set of 24 tapes broken up into four assortments were planned to be sold directly to schools. They would use a modified 2-XL with a headphone jack. Six of the games were later released as regular cartridges for the general public. It is unclear what happened to the remaining 18 games.

It contained a list of titles that had been released at the time, as well as a list of upcoming titles. Images of most of these cartridges have surfaced, proving that they were produced.

The most obscure release of the 2-XL, of which images of tapes have resurfaced, occurred in Canada. It is unknown whether the English versions of cartridges released in Canada were identical to the U.S. versions. However, it is known that some cartridges were released in French for the French-Canadian market by Grand Toys Ltd. Pictures of the General Information tape, Renseignements generaux have surfaced on a 2-XL fansite.  This tape strangely lacks any sort of artwork, implying that it may have been for the educational market, or even a prototype. A few short audio clips have been uploaded online.

According to a 2-XL Robot fan-site, there were also Mego 2-XL games released in France and Germany . Additionally, images of a Mego 2-XL that was sold in Italy have resurfaced on Ebay. However, no images of tape cartridges or lists of tape releases have surfaced for these countries.
