Title: Help reviving an old A3000
Post by: sdesros on March 25, 2003, 03:55:22 PM

I've got an older A3000 that used to have a CyberStorm MkIII in it.  It got transplanted into my A4000.  It's been a year and a few moves and I'd like to get my A3000 back up and running to test out some hardware I picked up a while ago (VideoToaster, Opalvision, etc.)

The A3000D has 2 megs chip, no fast ram (at the moment), KS3.1 and a 030/25.  I'm salvagine an older hardrive for use with it.

I turn it on, and get nothing.
I turn it on and hold both mouse buttons and get nothing.

I'm beginning to wonder if I forgot to change the jumper settings on the board to revert back to the speed of the on-board processor.  In which case, I'm a bit in a bind since I no longer have the CSMKIII instructions (I've moved since I did the swap).

Can anyone help?

Thanks...

Hi :-)

You must set these jumpers to the proper place to get something from your A3K :

J100  jumpers the other two pins than the ones you have now,

same for J104 (must be 1-2 ON)
same for J102 (must be 2-3 ON)

These jumpers are between the 68030 and Gary and FatBuster chips, on the left :-)

Your A3k should boot now :-)

Amigalement,

Jean-François.

Je vais les essayer lorsque je renterais a la maison.  :-D

Not quite... :P

It didn't work...

Well, I think I got further.

I'm getting a purple screen.  I'm not sure if it's looking for the floppy drive (it was flaky).  I think I'll try it with it disconnected next time.

Hmm... I can't fit a disk into the drive, perhaps because of this the drive is sending a signal that it has a floppy in and the A3000 is trying to boot from floppy?  Hmm...

Hmm...  The keyboard is at least reacting to a three finger salute. :P

don't forget the time honored method of making sure all the major chips on the MB are 'secure', namely gently but firmly press down on them to make sure they aren't loose.

Also, check out your jumper settings with our archived National Amiga A3000 tech page:

and other links on our A3000 page:

good luck!
