Need help with Progressive 3000/040

[amiman99]

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.

@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....
