i have found a nice small power supply that i plan to use as a internal replacement for my coleco, however it outputs only 5 volts, i have tested it and 5v only does work if you use a F18a as the video output device.  i am on the list to obtain an SGM in the future and i am curious if i do this mod am i shooting myself in the foot for later because if the SGM requires either 12v or -5v then i really need to obtain a different power supply now rather than later


can anyone help?

I use the F18a and SGM, along with an internal PS (only 5V is connected right now). The PS I use also has -5v and 12v taps available but they're not connected at the moment. You should be fine with yours though.

The SGM only requires 5V.

The SGM works fine with my orginal Coleco power adapter, so I doubt it requires anything special to power it.

Yeah, I broke down and bought one on eBay. But despite this, I still plan on pre-ordering a second unit from the 4th production run to support Opcode. The one I bought on eBay was a lot cheaper than some of the others, which all sold for $300+..
