           I recieved my 68020 Devellopers Kit Monday and plugged the chips
in the Lucas board yesterday. Well, I am one of those 1% whose board did not
work the first time it was plugged in. This is what happens: I turn on the
computer, the power light comes on, and thats it. The power light does not
start flashing.

           All my chips are socketed in correctly (the 68020 was very
difficult to plug in, but I made it). Most sockets are gold plated machine
screws. The OSC and U9 sockets are both gold plated machine screws. I made
sure that I dont burn any chips with static electricity. I never saw a spark
nor blue smoke coming out of a chip.

           I used a probe to check all signals. Pins on all chips had the value
they were supposed to have. Those that were supposed to oscillate between 0 and
1 did so. There was no signal at all on the FC2 pin of the 68000 connector, so
I shorted jumper 2, but that did not help. I re-checked to make sure the
Lucas board makes good contact with the motherboard through the 68000 slot. It
does.

           Then I checked the values on the 68000 connector right after a
reset. The *HALT line gets asserted for half a second, then goes back up to 1.
The *RESET signal oscillates for about 5 seconds. The data lines oscillate
for about 5 seconds, and then do not have any value any more. The address
lines oscillate and then stabilize to a constant value. The *VMA (or was that
*VPA?) signal oscillates in concert with *RESET. This all seems normal to me.

           All capacitors are plugged in correctly, with the plus side in the
sqare hole. If I pull out the Lucas board in plug the 68000 back in, the
power led starts flashing the way it is supposed to. What do you think I have
done wrong, and how do you think I could to find out the problem and correct
it?
