I got ripped off on a dead Amiga 4000

You will get this working and your hard work will be worth the effort.

have you tried to run the system only with the 4zorro slot daughterboard? this is the original one. the other is pretty much useless anyway (i dont think there is much need for isa slots in amiga except for par dps or pc bridgeboards)

also check the mb jumpers (especially these):


J100: CLK90 Clock Source
          1-2 Closed: Internal (68020/68030)
          2-3 Closed: External (68040)

J104: CPU Clock Source
          1-2 Closed: Internal
          2-3 Closed: External
both have to be external for 040 i believe.
for reference:

in the end it could be faulty kickstart rom too, alltough quite unbelievable, i had once or twice such an issue. if everything else fails you could try to replace these.

I'd suggest sliding all the jumpers up and down a bit as well, even if they are in the correct position.

Have you checked over your stuff with an oscilloscope or at the very least a logic probe?

The U177 chip, whatever that one does, has one of it's feet melted off.  It happens to be the chip right by the battery.  Maybe this guy didn't catch the battery replace in time.  Also the leads on the one I mentioned in the above post looks like crap.  New motherboard rev. B is what I need.  e-mail/pm if you got one.  I got buster chip part #390539-11, which is the later one I think.  So as long as you got the rev. B with the socket for the buster that's what I need.  And one that works of course.

it's a 74HCT174, you should have no problem finding one. Digikey has one for a dollar.

FC74HCT166T is the identifier on the chip below that it says 323820D and KS59310PBY

I don't nee that other one I guess because that just controls the RTC.  I also need a new IDE connector to solder to the motherboard.  Looking for both these things at the site.  Cannot find the FC74HCT166T chip.

Is it a DIP chip? See this:

For the IDE connector, see this: (could somebody double check that to make sure it's the right one?)
