 Hello Hernan.

 Look at Ian Stedman's homepage. (http://www.ianstedman.co.uk/Amiga/amiga_hacks/Amiga_Power_supplies/amiga_power_supplies.html).

 After doing the mod, just move J300 to EXT position and you're done.

 For better results, look in Aminet for "thick generator", since AT/ATX PSU don't have the signal wire.

Tick Generator. Not thick. :roll:

Anyway, what do we gain with the Tick signal?  I've always wondered.  I've been running without it with a AT P/S for years.  I know powerline timing is extremely accurate, but what's the actual gain in the A3000?

 Just some minor fixings, like time and date, and when in games.

 Thick: my mistake! :oops:

 Do you already know that's not my natural language, do you?;-)

So it is worth doing.
Time and date is kind of irrelevant unless you leave your A3000 on 24/7 like I do.  The battery backed clock is hideous.

So which is your natural language, Deutsch, or Espa­ol? :-)

 In Brazil?

 Esperanto!;-)

 Not joking: portuguese. And I learn english by myself!

 I also spoke 5 more languages (or use to):

 - german (kaputt!)

 - spanish (si, conosco y hablo)

 - greek (not that much, I've learned it in school)

 - français (oui, je parlais)

 - latim (mortus est)

 There is two ways:

 1- Carefully screw one or two of the screws into the PSU via the original holes in the back of the A3k. Then mark the other holes, take out the PSU, drill the other holes and put it back;

 2- Open the original Amiga PSU and put the new one inside the old case. That's the better-looking solution , but you need the new one fit inside the old case. In case you don't suceed, go to solution #1.
