Need help getting IIgs to work

#1 Sun, 10 Oct 2010 - 20:05

Just got a apple IIgs today and I am going to need some help with it since this is my first apple II.

I got it plugged it in to the monitor that I got too ( apple IIc green screen) and also the floppy drive keyboard and mouse flipped the switch on the back and the light turned on for a second and the blipped off. nothing else.

I opened it up and there are no cards in it just the board and the power supply.

Any ideas or am i missing something big here?

Unplug everything but the monitor and the power. Take a good look at the power supply - is it rated for 110VAC? Does it turn on for any longer length of time without any peripherals attached?

Have you tried playing with an emulator first? This online one can be tried without installing (much) on your modern Mac or PC:

Check out manuals online for the keystrokes to reset the IIgs and access the built-in control panel.

Either the power supply is bad or there's an electrical short in the machine somewhere. Start by pulling every single thing that's plugged into it, out. All cards, all cords, everything but the power. If it still doesn't work - it's most likely the power supply.

yea its the power supply.. when I turn it off I hear a click from it....Luckly I'm going to be getting another IIgs

The clicking is the sound of the oscillator frequency dropping in to the audible range. The power supply has some safety features, such as disabling power when it detects a no-load condition (ie, when the power supply isn't plugged into the main board).
