These devices are also available along with the computer in a complete package called the COM/PAC for sale around $500. While the computer is incompatible with Intellivision cartridges, Mattel also promises that hit software for that system, such as Advanced Dungeons & DragonsTron Deadly Discs, Football and Lock ‘n’ Chase, will get Aquarius versions. In all, thirty-two titles are planned for the first half of 1983, all in cartridge format, with more to follow by the end of the year. These carts are facilitated by a slot at the rear of the device, protected by a dust cover when not in use. Into this slot can also be inserted the Mini Expander, which can accept program cartridges, the memory expansion modules, or a combo of the two. It also offers two hand controllers (similar to the design of those of the Intellivision, but incompatible with the console) and two additional sound channels.

Since the computer has a Z80 CPU, it can also handle the vast library of CP/M software, via a promised Master Expansion Module that would add dual floppy drives to the Aquarius. This module would also allow 16K memory expansion boards to be added. Getting in on the 80’s home automation craze, a device called the Command Console will be sold for the Aquarius, allowing modules to be programmed to control aspects of the household such as a coffee maker and light fixtures. A version of the simplified graphics program LOGO, as well as  productivity products Fileform and Finform are announced with the system; the former is a file system and word processor, the later being a spreadsheet program.

At the Summer 1983 CES in Chicago, Mattel boldly announces that a “higher-end” version, the Aquarius II, is to be released later in the year. It is to sport 20K of RAM expandable to 64K, and a real keyboard with fully-travelling keys. Fully compatible with software for the first Aquarius, the later model is to offer 12K ROM and 20K RAM expandable to 64K. Its screen resolution is pegged at 320×192 and will sell somewhere between $130-$175.

Down the Drain

In April of 1983, the initial Aquarius is advertised and sold first in a four-city roll out: Los Angeles, Chicago, Detroit, and Atlanta. It is given a suggested retail price of around 150 dollars and is eventually offered nationwide. The system, however, tanks badly. While the official slogan for the Aquarius is “Smart Enough To Be Simple”, Mattel programmers loathingly suggest “System for the 70’s” as the advertising line, due to its extreme obsolescence. Heads start rolling at Mattel Electronics in early July, with 260 administrative employees let go. This is followed by a further 400 axed a month later, along with a culling of top executives. This constitutes around 37% of the workforce. A price slashing in November down to around $59 fails to improve matters for the Aquarius, and early the next year Mattel bins plans for the Aquarius II and pays Radofin to release them from the Aquarius contract. Surplus computer hardware and software ends up being sold to Odd Lot Trading Inc., an outfit out of New York City that specializes in selling discontinued merchandise.

These expensive projects, along with the collapse of the videogame industry, are the beginning of the end of Mattel Electronics. Even with the company adapting their original games and arcade licenses to the expanding computer game market, second quarter sales for 1983 have sagged to $3.5 million, compared to $24.9 for the same quarter the previous year. Tandy, having purchased Intellivision units for their branded Tandyvision One consoles at a set price at the beginning of the video game craze, watch as Mattel steadily offers discounts and rebates on their own machines, effectively cutting the legs out from under their version of the console. With Radio Shack dealers paying more than what consumers are for Mattel’s units, Tandy dumps their inventory and games and discontinues the Tandyvision line within six months of its debut in Radio Shack stores.

Mattel Electronics reports a loss of $166.7 million for the first six months of 1983, leading to division head Joshua Denham stepping down. Marketing whiz William Mack Morris is installed in the position in the summer of that year. He is famous in marketing circles because, as the president of LifeSavers, Inc., he came up with the idea of putting a simple blue-coloured dot in the centre of the company’s Breath Savers mints, greatly increasing their sales. Soon, a particularly catchy hook in a game that sets it apart from the others becomes known as its “blue dot” to Mattel employees. Morris lacks the magic touch here, however, and total losses of $229.3 million pile up for the year. With Mattel saddled with almost 400 million dollars of short-term debt, Morris lays off practically all the staff in hardware development, and another round of layoffs in the fall decimate the Blue Sky Rangers. On January 20, 1984, Mattel Electronics closes its doors.

The INTV System III, a home video game system by INTV Corporation 1985

But the mighty Intellivision refuses to go down with the ship. In February of 1984, Mattel reports that it has signed a letter of intent to sell all existing stock and rights to the system to Terrence E. Valeski, former sr. vice president of marketing and sales at Mattel Electronics, for 16.5 million dollars. Bankrolling the purchase with Valeski is Tangible Industries, Inc., a division of the Revco drug store chain, the largest such franchise in the U.S.. While the team face stiff penalties from Mattel if they fail to continue the Intellivision line, they float such ideas as using the Intellivision brand on other appliances like hair dryers and VCRs. Valeski insists that he is committed to continuing the Intellivision line as a viable game console, going so far as announcing a 3-D games for the Intellivision, via a licence for technology developed by Richard Steenblik of the Georgia Institute of Technology in Atlanta. The first such game for the Inty is to be Hover Force 3-D. Valeski subsequently incorporates a new company called Intellivision, Inc (changed to INTV in November 1984, when he takes over Revco’s share of the company). They release the INTV System III (aka the Super Pro System) in the fall of 1985, priced around $60. The System III‘s method of sale is partly retail, partly through mail-order, and it is nearly an exact replica of the original Intellivision, both inside and out, but with new game pack-ins. As a cost-saving measure, none of the licenses for the sports games are renewed, and a game like NFL Football is demoted to simply Football. INTV forms an agreement with Mattel to continue service of Intellivision equipment, as well as assemble new carts via a one-year contract. The “new” system brings in $6 million worldwide in sales over Christmas 1986, prompting INTV to hire back many of the original Blue Sky Rangers to finish unreleased games and create new ones. Between 1985 and 1990, when INTV closes its doors and the Intellivision is finally laid to rest for good, over 35 new games are released for the System III. This makes a total of 125 games released for the Intellivision system over 10 years. The Blue Sky Rangers currently have exclusive rights to publish  Intellivision system and games, granted to them by Ultimatte Corporation, purchasers of the Intellivision rights from Valeski in 1997.   Via Intellivision Productions,  a company set up by former Mattel programmers Keith Robinson and Stephen Roney, they continue to keep the system alive today, with Intellivision emulation packs for the Mac, PC  and various mobile platforms.

Its roller-coaster ride through the videogame industry nearly sinks Mattel itself. But through restructuring, the company eventually claws its way back to the top of the toy heap, and in 1996 re-enters the videogame industry with a vengeance under the Mattel Media label. They release the Barbie Fashion Designer CD-ROM for the PC that year, going on to sell 15.5 million dollars worth and breaking previous CD-ROM sales records. E.J., the 9-year-old daughter of Mattel Media’s Vice President of Design Andy Rifkin, is one of the designers. In the program, clothes are created and modeled by Barbie on-screen and then the designs can be printed out on special cloth-backed paper and assembled to be worn by real Barbie dolls. It retails at $44.99 USD and spawns a lucrative Barbie line of computer programs, such as Barbie Magic Hair Styler. It is hypothesized that Mattel has broken into the untapped female market for videogames, but others figure that the success has more to do with Mattel’s marketing and the fearsome Barbie brand-name.


Lasting Intelligence

Out of the ashes of the Intellivision system has come an amazing amount of quality product by spin-off companies, not the least of which is the continuing emulation work of the Blue Sky Rangers. In 1998 they release two emulation CD-ROMs, Intellivision Lives! for the PC and Mac, and A Collection of Intellivision Classic Games for the Sony PlayStation console. Both feature plenty of perfectly emulated original games, including some never seen outside of the development labs, along with historical information on their creation. Keeping the love alive for classic Intellivision games for continuing generations of video gamers, further Intellivision Lives! packages are released for the subsequent later generation consoles such as Sony’s PlayStation 2 and Microsoft’s XBox. Outside of emulation, some software companies created by former Intellivision programmers include Quicksilver Software – Castles I(1991) & II(1994), Conquest of the New World(1996), Starlet Command(1999); Realtime Associates – M:TG-Battlemage(1997), Crusader: No Remorse(console versions-1997); and Storefront Studios  Beyond Software, headed by Don Daglow of Utopia fame – Gateway to the Savage Frontier(1991), Tony LaRussa Ultimate Baseball(1991), Madden 97(1996), Byzantine: The Betrayal(1997), NASCAR Revolution(1999).

As pointed out previously, the Intellivision‘s unique control disc could be seen as a precursor to the modern D-Pad control scheme, pioneered by Nintendo in their Game & Watch handhelds and Famicom home console.  In 2013, the influence can also be seen when venerable video game developer, publisher, and distributer Valve Software introduce the Steam Controller, for use on PCs and presumably their Steam game console.  With two flat, round touch surfaces, Valve’s product is met with about the same acrimony from gamers as Mattel’s original controllers.

Carving out 15% of the video game market during its heyday (compared to 80% for Atari’s 2600) and selling around 3 million units across its production life (and another 3 million as the System III), the Intellivision may have come up second-best against Atari in the heated battle for videogame supremacy during the early 1980’s. But the Master Component, its varied sequels and components, and its thoughtful and sophisticated library of games continue to be highly appreciated by videogame enthusiasts. With continued support through emulation, Intelligent Television lives on.  logo_stop
