Title: Amiga A4000T Processor Board Problem (060)
Post by: techy101 on September 14, 2003, 09:57:20 PM

I have an A4000T with the 060 Rev. 4 processor board on it. it was booting sporaticaly for a while, and now has ceased to boot at all. upon close inspection i found that a chip on the processor board had a pin that was all bent and mangled. I straightned this pin back out, but it still wont boot. i turn it on and the hard drives spin up like there is no SCSI cable attached. I was wondering what i have to do to repair this problem.

Thanks,
Matthew

does it boot the workbench floppy?
If so, it might just be a harddrive
or software problem.

If it worked with the bent pin before, I think
it should still work, unless something fried
because of the pin.

Amigas can occasionally invalidate the harddrives,
sometimes just waiting awhile will allow them to
validate themselves and start booting. This might take 5 minutes or more.

The QuikPak 4060 motherboard is designed for use in A4000T's comes in revision 3 and 4 i think.

It will not boot from the floppy either. does anyone know where i could get a new chip, or CPU board??

Also, about the bent pin. it was bent up so that it was just barely touching the metal on the socket i think, so it may have been making contact sometimes, and not others. and Stamped on the board it only says "A4000T 060 Rev. 4"
