The Coleco Adam is a pc, as well as growth for the ColecoVision ( port 3), launched in 1983 by American plaything as well as computer game producer Coleco Industries, Inc. It was an effort to adhere to on the success of the business’s ColecoVision computer game console. The Adam was not really effective, partially as a result of very early manufacturing issues, as well as was orphaned in very early 1985.


Coleco introduced the Adam at the Summertime Customer Electronic Devices Program ( CES) in June 1983, as well as execs forecasted sales of 500,000 by Xmas1983 From the moment of the computer system’s intro to the moment of its delivery, the cost raised, from USD $525 to $725

The Adam statement got desirable press insurance coverage. Rivals such as Commodore as well as Atari nearly right away introduced comparable computer-printer packages. The business introduced a substantial advertising project, with tv commercials for “boys age 8 to 16 and their fathers … the two groups that really fuel computer purchases”, as well as print ads in nontechnical magazines like Time as well as Individuals.

The Boston Phoenix metro, observing that Adam’s $600 cost approached the most affordable cost for a letter-quality printer alone, mentioned “a nice trick if they can do it!” It was a technique; the computer systems were revealed behind colored glass that concealed the truth that they were hand-made as well as had non-working disk drive. In June Coleco guaranteed to deliver the computer system by August. In August it guaranteed to deliver a fifty percent million Adams by Xmas, yet missed out on delivery days of 1 September, 15 September, 1 October, as well as 15 October. Ahoy! reported that Coleco had actually not delivered by very early October as a result of numerous issues. Every month of hold-up might imply shedding the possibility to offer 100,000 devices, the publication reported, including that missing out on the Xmas period would certainly cause“inestimable losses” Chief Executive Officer Arnold Greenberg guaranteed in late September to deliver by “mid-October”, yet declared that Adam was“not, primarily, a Christmas item” The printer was the major root cause of the hold-ups; after it fell short to work appropriately at demos, by November InfoWorld reported on “growing skepticism” regarding its dependability, rate, as well as sound.

Greenberg declined to claim the number of devices he anticipated Coleco to deliver by the end of the year. The business did not deliver testimonial devices to publications preparing to release evaluations prior to Xmas, specifying that all were mosting likely to suppliers, yet confessed that it would certainly not satisfy the business’s objective of delivery 400,000 computer systems by the end of the year; Kmart as well as JCPenney introduced in November that it would certainly not offer the Adam throughout the Xmas period as a result of absence of schedule. In spite of wonderful customer passion, Coleco just delivered 95,000 devices by December, most of which were malfunctioning; Creative Computer later on reported that“the rumored return rate was absolutely alarming” One shop supervisor mentioned that 5 of 6 marketed Adams had actually been returned, as well as anticipated that the sixth would likely be returned after being opened up on Xmas. Coleco partnered with Honeywell Info Solution to open repair service store around the country. By December 1983 journalism reported that business execs at a press conference “fielded questions about Coleco’s problems with its highly-publicized new Adam home computer, which has been plagued by production delays and complaints of defects”, with the business just able to meet one 3rd of its Canadian orders for Xmas. Much less than 10% of Adam devices had issues, the business declared, “well below industry standards”.

An expert mentioned in very early 1984 that the business had

targeted a really unique location: mostly residence customers that have pupils or adolescent youngsters that are composing term documents as well as that often tend to be ignorant computer system customers. Coleco has actually attempted to make the Adam simple to utilize as well as appealing to that team, purposely omitting various other teams incidentally that [they] set up the equipment.

By March 1984 John J. Anderson proclaimed Adam as having actually created for Coleco “a trail of broken promises, unfulfilled expectations, and extremely skittish stockholders.” On January 2, 1985, after proceeding problems regarding Adam failings as well as reduced sales, Coleco introduced that it was terminating the Adam as well as would certainly be selling its stock. Coleco exposed that it shed $35 million in late 1983 (the moment of the Adam’s launch), together with a loss of $134 million in the very first 9 months of1984 Coleco did not disclose which business they were offering the stock to, yet mentioned that they had actually collaborated with this companion prior to. No last sales numbers were exposed of the Adam computer system as well as Growth, yet one expert approximated that Coleco had actually marketed 350,000 Adams in 1983 as well as 1984.

Technical information

In its support, the Adam had a huge software program collection from the beginning. It was stemmed from as well as suitable with the ColecoVision’s software program as well as devices, as well as, on top of that, the prominent CP/M os was offered as a choice. Its cost provided a total system: an 80 kB RAM computer system, disk drive, letter-quality printer, as well as software program consisting of the Dollar Rogers: Earth of Zoom computer game. The IBM PCjr cost $669 yet consisted of no peripherals, as well as although the prominent Commodore 64 cost around $200, its cost was very little reduced after the acquisition of a printer, tape or hard disk drive, as well as software program.

Like lots of personal computer of its day, the Adam was planned to utilize a television for its display screen. The SmartWriter digital typewriter filled when the system was switched on. In this setting, the system ran much like a typewriter, publishing letters as quickly as the customer entered them. Pushing the Escape/WP secret placed SmartWriter right into word processing program setting, which worked likewise to a modern-day word processing program.

Unlike various other personal computer at the time, the Adam did not have its STANDARD interpreter completely kept in ROM. Rather, it included an integrated digital typewriter as well as word processing program, SmartWriter, along with the Elementary Os (EOS) OS bit as well as the 8kB OS-7 ColecoVision running system. The SmartBASIC interpreter was supplied on a proprietary-format Digital Information Load tape cassette.

A less costly variation of the Adam connected into a ColecoVision, which supplied on among ColecoVision’s launch dedications that proprietors would certainly someday have the ability to update their video game system to a completely included computer system.


Several very early Adams were malfunctioning. A writer of the computer system’s guidebook reported obtaining “300 calls on Christmas week” from proprietors with issues; “some callers who were on their fourth or fifth Adam”, he stated. Faulty computer systems at the time might just be fixed by mailing it to Coleco in Connecticut. In spite of enhancing item top quality as well as the Honeywell repair service collaboration, the business might not boost the computer system’s inadequate track record. Troubles consisted of:

  • The Adam produces a rise of electro-magnetic power on start-up, which can remove the materials of any kind of detachable media left in or near the drive. Making this trouble even worse, several of the Coleco guidebooks advised the customer to place the tape in the drive prior to transforming the computer system on; probably these were published prior to the problem was understood. A sticker label on later Adams alerted customers to not activate the power with tapes in the drive.
  • Because Coleco made the uncommon choice of making use of the printer to provide power to the whole Adam system, if the printer’s power supply fell short or the printer was missing out on, none of the system functioned.
  • When took into Word processing program setting, SmartWriter might not come back right into the typewriter setting without the system being restarted.
  • The Adam’s Digital Information Load drives, although faster as well as of greater capability than the audio cassette drives made use of for completing computer systems, were much less trusted as well as still not as quickly as a floppy drive. At the time of Adam’s style, disk drive were still a preferred storage space tool for residence customers, yet by the time of its launch, floppies had actually decreased in expense significantly as well as were the recommended tool. Coleco ultimately delivered a 160 kB 5 1/4 inch hard disk drive for the Adam.
  • Software program designers that got technological info needed to accept an incredibly limiting certificate. Coleco required the right to check as well as require adjustments in their software program, required them to ruin supplies of software program if Coleco withdrawed the certificate, as well as forbade them from openly slamming Coleco by any means.
  • The whole computer system was challenging to set up in the manufacturing facility as the placing openings in the motherboard did not associate the threaded places built right into the situation.

To display the equipment at the June 1983 CES, Coleco determined to show a port of its ColecoVision conversion of Donkey Kong on the system. Nintendo remained in the middle of discussing a manage Atari to accredit its Famicom for circulation outside Japan, as well as the last finalizing would certainly have been done at CES. Atari had unique civil liberties to Donkey Kong for personal computer (as Coleco had for video game gaming consoles), as well as when Atari saw that Coleco was revealing Donkey Kong on a computer system, its suggested handle Nintendo was postponed. Coleco needed to concur not to offer the Adam variation of Donkey Kong. Inevitably, it had no bearing on the Atari/Nintendo bargain, as Atari’s Chief Executive Officer Ray Kassar was terminated the following month as well as the proposition went no place, with Nintendo choosing to market its system by itself.

BYTE reported in September 1983 that the Adam’s intro had “dominated” the Customer Electronic Devices Program in Chicago. Mentioning its $599 cost, packed equipment, as well as compatibility with ColecoVision as well as CP/M software program, the publication contrasted the Adam’s possible effect on the home-computer sector to that of the Osborne 1. Ahoy! reported in January 1984 that “Early indications were that the Adam would be a runaway best seller” yet the hold-ups, technological issues, as well as Coleco’s track record as a plaything business “should combine to keep buyers away in droves”, as well as forecasted that “there is no reason to think that the Adam will topple the C-64 from the catbird seat”.

The Washington Message‘s T. R. Reid gave “an ‘A’ for resourcefulness [but] would certainly need to extend to offer Adam a gent’s ‘C’ for efficiency” in January1984 While commending the key-board as well as SmartWriter’s convenience of usage, as well as calling the information pack “a reasonable compromise”, he defined the documents as “wholly inadequate” as well as“generally inexcusable” “A more serious flaw with Adam is in the hardware”, Reid stated, pointing out issues in an information pack as well as both the printer as well as a substitute, as well as the computer system’s unusability without a functioning printer. He ended that “I’d dearly like to” suggest the Adam, yet “for the time being, though, I’d advise you to proceed with caution”, consisting of validating that the computer system functioned prior to leaving the shop. Popular Mechanics in February 1984 was a lot more desirable. Calling the package “the most revolutionary concept in how to design and sell a home computer that we have seen”, it likewise applauded the key-board as well as SmartWriter. While pointing out imperfections such as the “slow and very noisy printer”, the publication ended that “Adam competes with and overpowers everything else in its class”, substandard just to the IBM COMPUTER as well as Apple IIe.

Compute!‘s March 1984 review also approved of the Adam’ s packaged, all-in-one nature as well as called the key-board “impressive”, yet mentioned extensive records of equipment failings. BYTE’s April 1984 testimonial was much harsher, specifying that“It is often said that if something sounds too good to be true, it probably is. The Coleco Adam is no exception to this rule” It called the tape-drive modern technology “impressive”, as well as authorized of the key-board, yet reported a number of situations of information mistakes as well as removals when making use of the disk drive, a buggy word processing program, as well as a BASIC guidebook that was“the worst I have ever seen” The customer reported that he was awaiting his 5th Adam after 4 previous systems malfunctioned in 2 months; just the key-board did not stop working. Speculating that “the computer was apparently rushed into production”, he suggested “don’t buy an Adam—yet. Wait until Coleco fixes all of the Adam’s bugs and delivers on all of its promises”, as well as ended “Coleco is [apparently] wagering the entire business on the Adam as well as it’s not yet clear that it’s mosting likely to win that wager”.

The Adam got some excellent evaluations based upon the top quality of its key-board as well as printer, as well as provided affordable audio as well as graphics. Its STANDARD interpreter, called SmartBASIC, was mostly suitable with Applesoft BASIC, which suggested that lots of type-in programs from computer system publications as well as publications would certainly deal with the Adam with little or no adjustment.

Sales were weak, specifically after the technological problems came to be apparent. Coleco shed $35 million in the 4th quarter of 1984 as returns swamped in. Formally, Coleco condemned “manuals which did not offer the first-time user adequate assistance.” Coleco reestablished Adam with a brand-new user’s manual, reduced cost, as well as a $500 university scholarship together with each system for usage by a kid (with $125 spent for each finished year of university). Less than 100,000 devices eventually marketed.

New york city City advertising and marketing company, Ketchum Marketing, won the project of advertising the computer system. The company staffed as much as take care of the job, as well as the reputation, of the brand-new service, yet company execs were surprised, when they opened up the New York City TimesJanuary 1985 early morning version, to check out, without any previous caution, that Coleco was deserting the computer system.

The Adam was completely terminated in 1985, much less than 2 years after its intro.

Third-party designers added to the total success of the ADAM after Coleco deserted the ADAM. Programmers such as Orphanware, In Residence Reps, Thomas Electronic Devices, Sanctuary Pensive, Eve, E & T, Micro Innovations, Microfox Technologies as well as others included multiple-density hard disk, memory expanders, speech synthesizers, serial cards, printer cards, IDE cards as well as various other equipment so the ADAM might adhere to various other computer systems right into a more recent modern-day age. In 2012, the majority of this equipment is still offered to update the ADAM.
