I've had pretty good luck lately so decided to try these and since I can swap boards now I decided to try to fix another one. This one is functioning the least out of any I have attempted so far. This board has a blank picture and does almost nothing.
I do see the red LED
68000CPU
Pin
6 - H -AS
7 - H - UDS
8 - H - LDS
10 - H - R/W
11 - H - BG
12 - H - BGACK
13 - H - BR
15 - Has clock single. Shows low on probe and CMOS light blinking
17 - HALT is low
18 - Reset starts L and goes H
19 - H -VMA
20 - E I don't this this on the schematic but is pulsing
21 - H - VPA
22 - H - BERR
23 - H - IPL2
24 - H - IPL1
25 - H - IPLO
Hope this helps.
