Starhopper Posted May 14, 2004 Share Posted May 14, 2004 Can anyone tell me the power supply specs for the 7800? I've just aquired a console, sans AC adapter and need to know the voltage and polarity Quote Link to comment Share on other sites More sharing options...
+Mitch Posted May 15, 2004 Share Posted May 15, 2004 9V DC 1 Amp. Mitch Quote Link to comment Share on other sites More sharing options...
Mot Posted May 15, 2004 Share Posted May 15, 2004 9V DC 1 Amp. Mitch I found one at the thrift sans adapter. I found that the Sega Master System adapter is the same, so I changed the 7800's power interface to use the SMS one. Quote Link to comment Share on other sites More sharing options...
Rob Mitchell Posted May 15, 2004 Share Posted May 15, 2004 I bought a new adapter ($1.49) and socket (0.49) from BGMICRO.COM and wired up a 7800. Works great! Rob Mitchell, Atlanta, GA Quote Link to comment Share on other sites More sharing options...
tantone56 Posted May 15, 2004 Share Posted May 15, 2004 I was lucky enough to get one with the system but I think that they may be hard to come by. Quote Link to comment Share on other sites More sharing options...
Chris-in-NJ Posted May 15, 2004 Share Posted May 15, 2004 I've got a spare adapter, PM me with an offer if interested. They sell for $14.95 at 4jays.com... Quote Link to comment Share on other sites More sharing options...

Rob Mitchell Posted May 15, 2004 Share Posted May 15, 2004 If anyone wants me to modify their 7800 to standard barrel socket and provide a new PS .. I can do that for very little money. Rob Mitchell, Atlanta, GA Quote Link to comment Share on other sites More sharing options...

Rob Mitchell, Atlanta, GA what do you mean? do you mean you can change the connection of the power supply. so, we can use a basic supply to run the 7800?

Rob Mitchell, Atlanta, GA what do you mean? do you mean you can change the connection of the power supply. so, we can use a basic supply to run the 7800? I can change the socket on the back of the 7800 to a standard barrel socket and provide a new power supply. Then you do not have to worry about breaking / losing that very rare original 7800 power supply. Rob Mitchell, Atlanta, GA Quote Link to comment Share on other sites More sharing options...

Bruce Tomlin Posted May 16, 2004 Share Posted May 16, 2004 Heh. And I've got a Colecovision AND a 7800 both set up and running "naked". Now that I have a CC2, I think I need to look into adding a hard-reset button for the 7800 so I don't have to power cycle it all the time.

I'm thinking of doing the same thing .. How do you do that? Also I am about to order a power supply and a standard power socket for my spare 7800. Anyone want me to order the same for them? I can modify your 7800 to use these standard power supplies also. PM me within 24 hours if you are interested.

Classic Pac Posted October 12, 2004 Share Posted October 12, 2004 Done mine long ago, and by the way you can pick up a multi-volt power supply at Best Buy which will run a 7800 for less than $10 Quote Link to comment Share on other sites More sharing options...
Bruce Tomlin Posted October 12, 2004 Share Posted October 12, 2004 Don't bother with a 7800 reset button. The only reason to have one is when using a multi-cart like the CC2, and that won't get reset because there's no reset line to the cartridge slot. And it's rather tricky to wire it up.

I will probably wire up a small box with a momentary open pushbutton in line with the power wire to the 7800 .. to cycle the power for my CC2. I'm tired of pushing the power button off then on to reset the CC2. I'm afraid that it will quit working. The current BGMicro prices for the power supply and power socket are $2.49 and $0.33 respectively. The power supply looks similar to the stock 7800 brick. I already have one 7800 converted and I'm going to convert the other one too .. and then I will probably sell my original 7800 power supply.
