Notes The Adam was Coleco's all-in-one solution to home computing. It competed with the Apple II Plus, Atari 800, IBM PC, Commodore 64 and TI 99/4A. It was fully compatible with Colecovision cartridges.

The Printer is a required component. It powers the rest of the system.
Related Items in Collection 2 5.25 disk drives, some manuals, tape software, cartridges.
Related Items Wanted Working tape drives, additional software, software on disk.

The Coleco Adam was designed and built in the early 80s as a complement to the Colecovision video game system. The Adam computer uses a similar internal architecture but adds four slots (that are reported to be nearly Apple ][ compatible) as well as a peripheral “network” to which everything in the system is attached. The disk drives, keyboard, controllers and printer all communicate with the CPU via this network. Interestingly, the Adam printer (a slow and noisy daisy wheel) is the power source for the entire system.

The Adam computer has a built-in word processor that is the default program run when the machine is powered on. Other software can be run from either the cartridge slot or the two high-speed tape drives built in to the front of the unit. Being a Z-80 based machine with reasonable memory (64K) the Adam was even capable of running CP/M.

The Adam still has substantial support including a place to buy parts or a full machine! eColeco.

A variety of program tapes for the Coleco Adam

These are some of the many tapes that came with the Adam.

A collection of Coleco Adam software cartridges

Also included were tons of cartridges including several duplicates.

This Coleco Adam was donated by Rick Collette along with several other very nice items!

I maintain a blog about the Coleco ADAM computer at

While I do agree that most of the 1st generation ADAMs were disfunctional, due to the electromagnetic surge, I feel it was a great computer system once they fixed that flaw in the 2nd generation. As for the tape drives, I find that programs load faster on them than the Commodore 1541.

I have my original Coleco ADAM from when I was young. It has dual tape drives, Buck Rogers, BASIC, lots of extras like controllers, and about 30 games that all work. It has a Commodore monitor that was on it since new. It has the printer (processor), and a spare processor module for the unit.

It work perfectly, and it is going up on the bay in a few days. I wanted to offer it to someone here first. Anyone with reasonable offers email me at

I want about $150 for it.

I bought an Adam for $20 at a church sale in its original box. It had the tape drive, a slot for cartridges, and the controllers. I had to use carbon paper for printing, as I couldn't find the Diablo I-compatible ribbons for it, just Diablio IIs. I gave it to my sister for her kids.

(Submitted May 25, 2007 09:34:31 by D.Butler)

Have one. My mother bought it and it just sat in the box. I took it out and now it is not in original box but the books and tapes are still in original packing. Never used. Would like to stree that this is never used. If any person is interested in purchasing....I will sell for a resonable price.

This was our first PC and to answer people's question here, I don't think it had a monitor. You used a portable TV for it. At first, It only had like two games or something and all you could do was text adventures and such. I wrote my very first College paper on the Adam; the good thing about it, was the printer; it was like an electric typewriter at the time with good quality printing; better than the dot matrix printers at the time. It was loud though!

Heh. I'm surprised by all the positive feedback here because I found the link to this website in an article about the top 10 /worst/ PCs ever made. The Adam came out as number 3.

What power supply (voltage, current, polarity) is needed for the floppy disk drives? I just inherited two complete Adam systems (one was the Colecovision expansion; the other was the stand- alone) but I can't identify the required wall- wart.

I had this computer as a kid with a plethora of games stored on audio tapes(yes actual audio tapes!). I think almost no modification was needed touse them with Adam other than drilling 2 well placed holes. Many hours of fun until I gave it away to a friend's little sister and she enjoyed it for quite a while.

I carried one of these in my pants for 2 weeks in 1987. Damn, the kids today have no idea how good they have it... with their 'palm pilots' and 'iPods'. Gives a new meaning to 'Planet of Zoom', I'll tell you that right now.

I remember a programmer for the Adam came to my Middle School to speak. He brought in the computer & demonstrated some of the programs for it (mostly games).

I also bought the Adam for my son's schoolwork and I still have it. Waiting for a museum that would want it.

ahh... a great machine... origionally bought one for my son for schoolwork. He used it right through to finishing high school. (that is... when he could get Dad off the chair. lol)Bought him a 486 clone when he went off to university. Gave it to a friend for her young daughter... it wound up in the garbage... such a waste

(Submitted February 5, 2005 15:28:43 by coming soon...)

What an awesome computer. Did you know that Adam had a second Garden as well: The Garden of Edom.

You'll never believe it, but I'll bet this computer is really worth something more than what you're imagining right now...just give it some time. Consider it the best insider trading you're given for free and the honest way...

God Bless You!
