Interested in the many games & systems of Intellivision?  Well, lets open the vault to take a look at some of the rarest & my favorite items. 

One thing I love to collect is rare games. Some of the rarest games in my collection include Spiker super pro volleyball, Congo Bongo, Stadium Mud Buggies, Tutankham, & Learning Fun I. If you are lucky enough (& have the funds) to acquire all 125 games originally made for the Intellivision system, you may want to start to trade up, or start collecting variants, or hardware. This is what I have done. There are many games that were made in multiple countries, therefore there are many games with different languages in the manual. These games can be found at flea markets, yard sales, or at online auctions.  There are also different types of Intellivision systems.  Below, you will see many of the rare games, systems, & extras for Intellivision.

SPIKER Super Pro Volleyball   Spiker is the hardest Intellivision game to obtain of the original 125 games made in the 1980's.  INTV was in the process of closing it's doors when this game was released, so there are not many of them out there. It is usually at the top of every Intellivision collector's "Want List".  If you were lucky enough to get one early on, you are one of very few that have the highest priced Intellivision game (by collectors standards).    This game was originally produced in the INTV box, complete with instructions. The original cart label read "SPIKER Super Pro Volleyball".  Right before INTV shut it's doors, they offered this game by mail order only. INTV was about to close and did not have anymore boxes or labels for the game, so they sent the carts out in a sealed bag with instructions & a makeshift label. The label read "VOLLEYBALL" in bold, outlined text.
	Super Cobra   Super Cobra is one of the Parker Brothers games made for the Intellivision. It is somewhat rare in the United States. This game was released in two versions.. English, & French. The English version came with a gold labeled cart, while the French version had a silver label with the box image on it. The French version of this game is quite impossible to find.  Another difference is the instruction manuals. The French version game comes with two sets of instructions in both English, & French. Both covers have the Super Cobra text in black & white. The English version has the text outlined in blue. *(Notice) The differences in the boxes. The English has the blue line at the bottom. The French version does not have the blue line, & has French text on the cover.   Originally, there were no overlays made for this game. The overlays you see in the lower picture are from the "Orphan Overlay set".
World Series Major League Baseball    The World Series game is one of the best, & hardest games made for the Intellivision system.  You will need to have the ECS computer component module, along with your Intellivoice & Intellivision system in order to play it. The graphics were way ahead of their time with multiple angles of the field, and stats.  I currently have two of these games, a factory sealed one, & the one pictured.   After the MLB copyright ran out, this game was released as "Super Series Major League Baseball". This rare variant of the game is very hard to find. It is sought after by every major Intellivision collector.
	FATHOM    Fathom is the rarest of the Imagic games made for Intellivision.  I love the fact that all of the Imagic game boxes look similar in their foil printing.  The game itself is not all that great. I rate it average for game play. The fact that it is so hard to find, drives the price up on it.   The Fathom game shows up from time to time at auction and always goes for big bucks. Why it is so hard to find is beyond me. I would think that Imagic games like Dragonfire, or Ice Trek would go for more purely for the game play.
Triple Challenge    One of the greatest marketing tricks I saw was when Triple Challenge was released. This game is actually three games in one!  It has Chess, Checkers, & Backgammon all wrapped up into one game.  But, here is the funny part... If you already have these games by themselves in Mattel boxes... you have this game.  Leave it up to the Intellivision guys to re-release 3 games in one package & say it's a new game.    With all of that aside, this game in it's box is another of the rarest of the original Intellivision games.  I play chess on it from time to time, & have even produced it's overlays.
	Defender    Defender is the rarest of the Atarisoft games. Atari cashed in on the Intellivision market by making three games.. Defender, Centipede, & Pac-Man. Although Pac-Man was by far their biggest seller, Defender proved to be the one most wanted by collectors.    The Defender game plays much like the arcade version with a lack of graphics.  It is still fun to play, even though Atarisoft seemed to do little to make the game better than the Atari version.  All of the Atarisoft games are signified by their hot pink colored boxes.
River Raid    River Raid is one of the many Activision titles made for the Intellivision. It, along with Worm Womper, seems to be the most saught after games by this company.  It is one of my favorites to play. One thing that Activision messed up on with this game was the overlays. The River Raid overlays have been made in a bad run of ink it seems. If you have this game, you may already know that the white paint on the back of the overlays seems to peel off with age.  To have a mint set of the overlays is rare.
	Stadium Mud Buggies    Stadium Mud Buggies is a great title. This game was released just before the Spiker game just before INTV closed. The game is very rare in it's complete form with box, instructions, & cart. The overlays you see in the picture are from the "Orphan Overlay set".    The game play is similar to the Motocross game, in that the landscape & view seems to be from the same original design. This game is considered very rare, and is definately one to look for when collecting Intellivision stuff.
Tutankham    Tutankham seems to be the rarest of the Parker Brothers games. I have two of these in my collection... one is sealed mint in it's original shrinkwrap. It is a very fun game to play if you like D&D style game play. The Parker Brothers boxes are by far the most sturdy of all games made for the Intellivision.  They will withstand many years of abuse.    In good condition, this game will fetch very high dollar amounts at auction.  It is a very collectable game for the Intellivision enthusiest.
	Learning Fun II    Learning Fun II was made as the sequel to the Mattel game Word Fun. It is a rare game along with it's sister game.. Learning Fun I.  Because Intellivision was already on it's way out in the 80's, there were not many of either of these games sold.  The game play of this game is somewhat remedial by todays standards. But, the drive to have a complete collection of games seems to push the Intellivision collector to seek these "not so great" titles.  Always fetching large sums of money, Learning Fun I & Learning Fun II are considered nearly impossible to find these days.
Congo Bongo    Congo Bongo is one of the hardest games to find for the Intellivision. It was the only game made by SEGA for the Intellivision system.  I remember playing this game at the arcade when I was young. Believe me, it doesn't look as good on the Intellivision. Regardless, it is rare, so I must have it in my collection.  The game was originally made without overlays, but did come boxed with instructions. The box & instructions had  very nice graphic work, as did the game cart. Getting one of these for your collection is a must, whether it be boxed complete, or not.    The overlays for this game have been produced in the "Orphan Overlay set".  The game play is o.k. The graphics are a little on the blocky side, but that is to be expected from all of these Intellivision games.
	Slam Dunk Super Pro Basketball    I found this game very interesting from the start. It took me quite a long time to first acquire it, but once I did, I noticed something pretty interesting. Did you ever notice that this is the only Intellivision game that featured an actual picture on the box?  That blew my mind.  Who are these guys?  And also, where are they now?  Just some food for thought.   The gameplay on the Super Pro Basketball was top notch for it's time. I still like to play this game from time to time. Although it did not originally come with overlays, it did come boxed with instructions.
STONIX    STONIX is one of the many games being made by "Intelligentvision".  It one of the best games ever made for the Intellivision.  This game boasts all of the original Intellivision items... box, instructions, overlays, & cart!   Intelligentvision produces a limited number of new games for the old system. Once the short run of games is sold out, no more will be made.  There were 250 copies of STONIX made, 150 of Minehunter, & 100 of Joe Z's 4-TRIS. They are currently working on their next title, in which only 100 copies will be made. Look here to see more about Intelligentvision!
	4-TRIS    Joe Zbiciak (aka Joe-Z), is well known throughout the Intellivision community. Being a master hardware & software expert, he produced the now famed 4-TRIS game.  This game was first produced as a demo for the Philly Classic gaming expo in 2001. Because there were so many people that wanted one,  he decided to do another run for the Intellivision fans.  It has been years since then & Joe still gets e-mails from Intellivision collectors wanting the great game.  With help from Intelligentvision, he has decided to make this game once again in a limited 100 game run!  These games are currently being made by Intelligentvision, so if you want one... you better hurry! (Go Here).    You can see the original 4-TRIS game in the pictures at the left. The white box is the original regular edition. The purple box is that of the new re-released Intelligentvision version.   Getting one of these games is like finding the "Holy Grail"! Look below to see the total number of 4-TRIS games ever made!  4-TRIS (Philly Classic Edition) - 40 Copies made  4-TRIS (Regular Edition) - 20  Copies made  4-TRIS (Intelligentvision Edition) - 100 Copies made
MTE 201 Test Cartridge    The Mattel Electronics 201 test cart was made by Mattel for service on the 2109 Intellivision system. By putting this cart into the system & powering up,  you can see where a problem may lie in the hardware.  This service cart is accompanied by an instruction booklet that tells you how to prform the diagnostic tests.    This cart is considered to be very rare.  There is also a test cart for the Intellivision II which is even more rare. These items are usually found in a die-hard Intellivision collector's stash.
	Schell Electronics INTELLICART    Being a great hardware master, Chad Schell developed the Intellicart so that a user could play Intellivision games on the computer.  These carts made it possible to download games from respective sites, & lay them via their own Intellivision system.  This was done by hooking up the cart to the Intellivision system & to the computer at the same time. This then let an individual play the games as they were meant to be played... on the original system.  These carts are very hard to find. I am not sure exactly how many were originally made, but I do know that he does not make them anymore.
Compro Videoplexer    With the Compro Videoplexer, a gamer can plug in multiple games at the same time instead of changing carts out.  Very few of these units were originally made. With a capacity of eight games, this is a great add-on for the Intellivision system! Simply push the numbered button of the corresponding game in the videoplexer & it immediately goes to that game. After years & years of collecting, I was able to just get one recently.    The Videoplexer is very rare indeed. It comes in a box complete with instructions, & a lid for the games. It is packed in a styrofoam split shell. The one I have pictured is in mint condition & works great.    If you have the means, pick one up. You will not be disapointed!
	New ECS computer components    Recently, I was able to buy some new ECS (#4182) units along with some ECS games.  I also picked up some Intellivision II master components.  These units were all brand new in their original boxes. It was cool that they were even sent to me in the original Mattel shipping boxes. To get a new system in the box is a dream come true. If you ever see a game or system that is new, you should keep a close eye on it.   Items like these are very hard to find anymore.  Most of the hidden stashes of these 20+ year old games have been found.    But, we are hopeful that one day a box of Spiker volleyball games, or Mud Buggies will pop up somewhere.  Keep your eyes peeled! Comming across a find like this is like hitting the lottery. All of the systems that I purchased in this lot were in mint condition. The ECS computers have never been out of their original shipping box from Mattel.
Intellivision Systems   I currently have roughly 20+ Intellivision systems in my collection. There are different models of Intellivision systems, but all will play the games. Systems in my collection include the following-  Original gold Mattel system  Model 2609  Intellivision II system  Model 5872  Austrailian PAL system  Model 3668  Digimed gold PAL system  Model 5368  Radio Shack Tandyvision  Model 58-1000  Sears super video arcade  Model 487.75022  INTV system III  Model 3504  INTV Super Pro System  Model 3504  Digiplay system II  Model 5872  Sylvania system  Model MC-100     Not everyone collects these systems, but after you get all the games, you need something to do.
	System Changer    For all those that had Atari games, the Intellivision system changer was produced. By plugging this system in, you could play your Atari games through the Intellivision system! The system # 4610 was accompanied with instructions.  Yet another very rare item for the Intellivision collector.
Intellivoice Voice Synthesis Unit    The Intellivoice was probably the most exciting add-on for the Intellivision.  It was the first video game system that had actual voice in it!  Mattel then started making games that were enhanced with voice by using this synthesis unit like TRON Solar Sailer, Bomb Squad, Space Spartans, & my favorite... B-17 Bomber.    The Intellivoice is not rare per say, but is an intrical part of any & all Intellivision collections. The system (#3330) originally came boxed with instructions.
	Music Synthesizer    The Music Synthesizer (#4188) was one of Mattel's all time flops.  They didn't seem to sell all that many units. It is actually a good unit. The only problem is that there is only one game that can be played with it! The game Melody Blaster was developed for the Synthesizer, but no others. Word is, that there were more games in the works for the system, but were never realized because of the declining video game market at that time.     The unit came with multiple instructions in a long Mattel Intellivision box. Funny, they were almost the same size as a regular keyboard!    Items like these are usually on the tail end of a collection list. It is one of those items that you would like to have, but are not upset if you do not.
