Amiga 2000 battery ?

Will an Amiga 2000 work without the battery on the motherboard ? Does any one know what the Tick signal (Pin 14 on the Powersupply connecter) should be ?

Yes.  The only thing you lose is the battery backup feature of the real-time clock (RTC).  (Each time you boot the Amiga it'll think it's 1978 until you set the clock by some means.)

Does any one know what the Tick signal (Pin 14 on the Powersupply connecter) should be ?

Don't know.  I think it might depend on the region...  I never understood the power supply well enough to tinker with it much.  ;-)  I did find this link in google's cache, though.

The battery on an Amiga powers the date and time clock, not the system's timing, so you can run an Amiga without a battery (as many Amiga 500 owners can attest!)

D'oh!  Beaten to the reply!

A special note for A3000 users: The RTC has a small amount of memory also backed up by the battery which is used to store settings for the motherboard SCSI controller.

I wonder if that's why my Amiga 3000's floptical drive stopped being recognized?

When I changed the battery on my A3000, I had it "unpowered" for several days, and when I soldered on the new battery and turned the machine on, everything worked like a charm...

Thanks for the info, I bought a MotherBoard, it didn't have the battery. It does not work, I thought maybe it needed the battery. I was also checking my power supply, every thing looked good, but I wasn't positive about the Tick signal. It from the link, it looks like it is a 60hz (In USA anyway) signal for timing.
