| Apple IIGS boot requirements? | |
| Posted by: PotShotScott on 2023-05-06 18:05:11 Question as I can’t remember from my childhood in middle school. I have a IIGS that I’ve gone over. It chimes twice and the LED comes on. I don’t have an Apple monitor so I was going to try composite video. I’ve got all the proper Voltages but the 12V rail is 11.70V. I don’t have any disk drives or OS materials at the moment. Clock battery is dead but I haven’t seen any mention of not booting due to dead clock battery. Question - why does it chime twice and what would I need to have in the machine to see video or some sort of life when I turn it on? | |

That is likely what you are hearing. You’ll probably see that if you hook it up to a composite monitor. | |

| Posted by: PotShotScott on 2023-05-07 21:15:59 Thanks! I'd like to do the clock battery before I get too much further. Has anyone swapped the original 3V battery with a modern CR2032 socket? | |
| Posted by: volvo242gt on 2023-05-07 22:22:57 This is what I'm using on mine. Fits nicely under the power supply. I use two Energizer Lithium AAA batteries for the correct 3.6 volts. 
Battery: IIgs ROM0/1 CaddyThe battery in the ROM0 and ROM1 IIgs system connects to the motherboard using wire "legs". These legs can be easily cut close to the battery. This provides a simplistic way to remove the battery and
