Coleco Adam: Replacement Power Supply Update

Recommended Posts

I am happy to announce that you can now order the replacement power supply again (rCAP) with a custom cable and not have to cut off the cable on your printer. It also works with voltages outside of the USA and Canada so you can order from anywhere in the world!

Milli is no longer making the rCAP Power Supply, but you should still PM him here as well as on the Coleco ADAM Facebook group (Bill Hicks) to see if he could set you up with something.

 

Everyone seems to be using the Mean Well RT-50A power supply now either installed in an external case or mounted internally in the open area next to the 3 Expansion Slots.

Or there is this expensive option:

The Coleco ADAM is the only videogame and computer system on the market that has the custom molded female DB9 power connector that plugs into the male DB9 power connector on the right side of the ADAM memory console.

 

While its true that other computer and videogame systems use the DB9 connector for joysticks and serial ports, as far as I am aware only the ADAM computer system is the only computer and videogame system on the market that decided to use the the custom molded female DB9 power connector.

The original Coleco ADAM power supply that is built into the Smartwriter printer is a amazing design with a total of 4 different voltage outputs. We are all familiar with the regulated -5 volts DC output, + 5 volts DC output, and the 12 volts DC output. However coming out of the power supply is also 18 volts DC unregulated voltage that powers the ribbon solenoid in the daisy wheel printer. When measured with a digital meter the unregulated voltage output when not under a load is around 22.5 volts DC, and around 18 volts DC when under a load when printing a document.  Since most people do not use the Smartwiriter printer anymore many people forget the orignal Coleco power supply offers 4 different voltage outputs, instead of 3. Now on the printer/console 9 pin interface cable only 3 of those voltages are sent to the memory console. One has to measure the 4th voltage level from the Molex connector inside the Coleco ADAM Smartwriter printer power supply.

 

Therefore if one is not able to repair their Smartwriter printer power supply, one would need to wire up both a regulated 18 volts DC power supply for printing and a -5 volts DC, 5 volts DC, and 12 volts DC power supply. There would be two separate third party regulated power supplies if one needed to use the Smartwriter printer since no one makes a one power supply solution that offers 18 volts DC, -5 volts DC, + 5 volts DC, and 12 volts DC.

Most are looking to eliminate the printer not power it :)

But without the printer...how would you ever print out your winning certificates from Jeopardy 😁 :

LOL...forgot about that. Well get a dot matrix/laser patch for Jeopardy created to get up with the times. SAVE THE PRINTER and support MILLI POWER!!!!

I wonder if Family Feud for the ADAM has a winning certificate also. When I played Buck Rodgers the Supergame and other supergames I once and a while hit the print button on the keyboard when I was on the hall of fame screen, and the original Coleco ADAM daisy wheel printer would print up a hall of fame screen with the names and top scores.

 

Its my understanding that the 2+ unreleased fully functional Coleco ADAM AdamNet serial/parallel interface boxes that uses the Adamnet cable emulates 100% of all existing ADAM software without a software patch needed. The Coleco employees that own that device can use a dot matrix or Laser printer to print the Jeopardy certificate.

 

All third party released serial/parallel ports do not work as good as the original unreleased Coleco ADAMnet version. The released MIB3 card that plugs into an internal slot in the ADAM computer does not use ADAMNET, and therefore requires 100% software patching. None of the existing software patching works with Jeopardy, and the supergames, and a new patch would need to be created for supergames. The software pathing is limited to Smartwriter, AdamCalc, Recipe Filer, and other programs.  In the ideal world someone should create a ADAMNET to USB Smartwriter printer emulator piece of hardware that would completely emulate the Smartwriter printer without any software patches. Then a HP color or black and white Laser printer could be used with support for modern printer communication languages. Also a added extension software code to the ADAMNET to USB Smartwriter printer emulator would be over 1,000 lines of code for advanced color graphics capability. But then in the ideal world a HDMI graphics card that plugs into the side Adam expansion port that offers a new 80 column version of Smartwriter with built in spelling and grammer as one types (the graphics card and Smartwriter would be firmware upgradable with the Ultimate SD Wafer drive).   

   

I prefer external power supplies for the Coleco ADAM and ColecoVision. However the one advantage of adding a internal power supply to any device, is that one is except from the level VI energy requirements that the DOE put in place back in Feb of 2016. Only external power supplies have to be level VI complaint.
