Anyone here got the Progressive PPS 68040-3000 A3000 accelerator and knows how to jumper the A3000 desktop MB correctly?
I'm pretty sure that I tried every combination and no boot from it.
The 3640 works fine with A3000, but PPS is not.
I checked the CPU in 3640 and it works fine in it, and also I checked the 50 MHz oscillator and checks out fine.
A manual would be nice too.

Thank you for anyone's help.

Thank you for anyone's help.

If you tried setting the jumpers to external clock an nothing worked, could be an issue with the card.

Does the system give any screen colors? Have you tried the caps lock test to see if the cpu is responding?

Is it an upgraded PPS or normal 50MHz XTAL?

@matt3k
Jumpers were set to same settings as A3640, and many other combinations.
no colors, just black.

@VingtTrois
The oscillator is 50MHz (in a socket), it was verified working with a working CPU.
It does seem dead

I'm looking for a manuals which shows correct jumper setting on A3000.

Do you have the ZIP RAM issue mentioned on the Amiga Hardware Database page?

I have tried on 2 A3000s. One has 16MB Page mode ram, and other is 1MB chip and 1MB fast with DIP. No zips.
Both of them would not work with the accelerator.

I did some VCC continuity checking on all IC chips and I noticed that one of the DS1000k-25 delay chips has a no continuity to other VCC sources. Looks like a high resistance, almost an open, which gives around 1.8V instead 5V (4.85V in this case). In the datasheets it states that VCC s/b between 4.75-5.25V.
Troubleshooting will continue next day....

Did you get the accelerator to work?

The card works in A3000T with the following jumper settings:
J100 3-4 (EXT)
J102 2-3 (INT)
J104 2-3 (EXT)
J105 -
J106 1-2
J107 1-2

The same J100 - J104 settings should work in A3000 desktop.
