SmartBASIC - A Coleco Adam Forum

I’m looking at this project. The old design is quite tired now, and not very efficient. There are options already that provide what is needed. I’ll measure the space and get the specs from the technical manual and see what makes sense economically.

Replacing the power supply in the printer or replacing the printer with a new power supply?

Replacing the power supply in the printer. I do see a lot of people using standard cage supplies inside their expansion bays. I think the only thing wrong with the Adam printer is the loudness, and apart from that it's pretty decent. Just needs a more efficient and better regulated power supply.

Is this project an academic exercise or is the PS in the printer prone to malfunction?
As for the printer itself, aside from being loud, it's also quite slow. But frankly, neither of these is a major issue for me as compared to the lack of a tractor feed...

Mine failed, mostly through age and dry caps. Given the design, a whole new power supply would cost less than the caps. The power supply also is only 45% efficient, and modern designs are 89-92% efficient. Half the power draw at the wall.

Please post your PS design when done here. It would be great to have an alternative option should the PS in my printer die...
