Hi 98PaceCar

if your A3000, is off from years, it's normal that something is lack.

The first thinks to do, is remove/clean and reinstall all the socked stuff (ram, kickstart, cables, connectors).

If you are lucky, all taht should fix the problem.

If not, could be some capacitor-fault inside the PSU or on the mobo.

Ciao

You'll have to show me where you get this from because it doesn't make sense. There is no reason I can see for this to be true.


Never heard before too!! it should be a "nonsense" and unusefull behaviour!

Just to check my reasoning, I located my A3k schematics, C= P/N 314677-01. The clock and ROM chips are on sheet 3. It clearly show that the battery never powers the ROM. In fact, unless D191 were to fail, no current could flow from the battery to the 5V rail.


i haven't direct experience about A3K.

Has tha A3K, a rechargeable battery? like the A4K has?

Can you post me the related schematics part?

If you have a 25 Mhz CPU, set the JUMPER to 25.
