Price Check - Coleco Adam

[whovian]

I have a few cassette games for the coleco Adam. The ones of note are Donkey Kong Jr. and Buck Rogers. They are in mint shape, and are not sealed. I was wondering if anyone knew of a rough price guide, list of games and programs, and how much blank tapes are worth. All are Adam branded.

 

Any help would be appreciated. Also, if anyone has an extra power cord for the old stand-alone Adam systems, I could use an inexpensive one.

$3 - 5 on blanks, $10ish on games other than Buck Rogers... Buck reproduces in sewers (as it was a pack-in and over produced as an extra) It would be mostly blank tape price.

Wow, I was thinking about letting some go.... may have to post another thread.

Anyone have a extra set of cords for the Adam? I'd like to try it out.

Do you have the printer for it? That's the main power supply. Without that, you're gonna have a rough go of it getting the machine running as standalone power supplies are still hard to come by as they were never 'officially' available-- just hacks usually. For the interconnect cables from the CPU to the keyboard and the disk drive, you can use standard 6-pin phone cords.

Oh, and as for Buck Rogers, it's not much in the way of price, but don't forget, it's a Right Hand Directory DDP. Most game DDPs were. Data DDPs and blanks were Center directories. Good to keep that in mind if you're copying "Super" games.

 

For those who don't know and still care, the Right Hand Directories worked well for games since they were linear in loading patterns from scene to scene, where as Center Directories were used for most data DDPs to make it quicker to get to the data needed in a more random pattern. IE, if the Directory was at the 128k mark (Center Directory), it was only 128k from the furthest block of data on a 256k DDP. Where as on the Right Hand Directory, the Directory being at the 0 or 1k mark, it could be as far as 256k to scan to the last block on a DDP.

My parents bought me one of these when I was a kid. I was pissed at them they didnt buy me a "real" computer Looking back I am rather confused why I never got any CV carts to play on it. I know my 2600 carts didnt work, hey I was really young, lol! My mom ended up selling it perfect condition in boxes for TEN USD a long time ago in a garage sale...oh well.

AHHHHHHHHH! $10 in the box!

 

Someone was a lucky bastard!

 

Haha, sorry. I love my Adam though.

 

By the way, I thought there was an agreement that DK was not to be released for the Adam, DDP. Did that not apply to DKjr as well?

[Murph74]

That alwasy confused me, too, Jeremy. No answer for ya from me though. As I understood it, Coleco had the home CONSOLE rights to DK, while Atari had the PC rights. (No clue on DKJ, but would make sense to be the same)

 

My only guess would be that the DK DDP may have been claimed to 'technically' play on the ColecoVision board within the Adam, and not the Adam board, hence being a console game. I tend to recall the standalone Adam had 2 different motherboards inside-- one was essentially a ColecoVision, the other was more or less the 'expansion module' Adam. This is a total shot in the dark as to how or why it happened.

If I'm not mistaken Atari had only purchaed the floppy disk rights to Donkey Kong. The ADAM version was only released on DDP.

I don't think that would have been it specifically, as Atari also had cartridge versions of DK on Atari Home Computers.

Coleco had a fully working Super Donkey Kong that was supposed to be released on the Adam and the Super Game Module but it was finished right at the video game crash and did not see the light of day as anything but a rom

 

SDK was better graphics, more accurate color, smoother animation, animated cut scenes, and had the missing levels

[whovian]

I sure wish that had been released.

I think you're misinformed here. Coleco *DID* release a Donkey Kong Supergame. It is the DDP that we are discussing here. Came out about the same time as Supergame Zaxxon and Supergame Donkey Kong Jr. A "Supergame module" was never released, just the Adam.

 

The graphics (far as I could tell) and colors were the same. It did add the cut scene animations and the pie factory.

 

There is also a 'hack' of the Adam Supergame that is available as a ROM, or sometimes as a homebrew cartridge. It's a stripped down version of the Adam game from what I've seen.
