Does the Colecovision have a proprietary A/C adaptor or can any generic one will do? What is the voltage?

Pinout 

1: +5V (white)

2: -5V (blue)

3: +12V (red)

4: GND (black) 

Totally non-standard.

Thanks!

Hey Zeus I have an extra that I think is still good if you want me to check it out. I'm sure we can make an agreeable trade for it.

the thing is huge and takes up my whole outlet and it heats up like a bitch!

you could probably use a PC power supply for that. it makes +5 -5 +12 -12

Yes, an AT power supply to be precise.

there would be no way to turn an ATX power supply on without a motherboard!!!! so yes, of course an AT power supply would work. like those found in PC computers older than Pentium 2. any K-2, K-3, K-4s Pentiums, Pentium Pro ect... 486, 386, 286, 8088, 8086 ect...

The wall-mounted brick is pretty awful, but there's also a version that's designed to sit on the floor, with a cord seperating it from the outlet. I wish mode systems did that actually, since all my power bars get blocked up by one or two power supplies

Actually, there is a way to turn on an ATX power supply. You just need to ground pin 14 (should be the green wire) and it will turn on. Make sure you have a load on it before you turn it on though or you may have problems.

okay you can turn it on but you'll need to have that load. A standard AT P/S needs no load to work properly.

That's right, green is power on for ATX power supplies. And I could suggest a 10 ohms, 10 watts resistor on the +5v line to keep the power supply stable.

Yeah, but you will have that load.. The Colecovision.. :-)

Of course, I agree.. I used an AT for my Adam.. They're easy to acquire.

1 thing to watch for tho, is the on/off switch. My AT supply had its on/off switch at the end of about 10" of cable, so I had to reroute and mount it in the AT PSU case. (Well, I didn't HAVE to, but I didn't like the concept of the on/off switch just dangling.. hey..
(Dangerous.. Thought happening.. I'd run if I were you...)

I wonder if I can fit the AT PSU inside my Adam. In my spare tape drive bay or where the card slots are... hmmmm.. Then I could just run the switch to the Adam front panel...

Hmmm...

This is maybe where an mini-ATX supply might work better...

Great.. Now I have a headache.. :-)
