SE and SE/30 use the same logicboard power connector. I have tried this myself with SE and SE/30 analog and logic boards. I have now checked with the Apple Guide to the Macintosh Family Hardware as follows:

Signal assignments for the power and video connector from the analog board

to the logic board in the Macintosh SE and Macintosh SE/30 computers:

:

1 GND Ground

2 GND Ground

3 GND Ground

4 GND Ground \

5 GND Ground

6 -5V -5 volts

7 -12V -12 volts

8 GND Ground

9 VIDOUT Video output

10 /HSYNC Horizontal synchronization

11 /VSYNC Vertical synchronization

12 +5V +5 volts

13 +5V +5 volts

14 +12V + 12 volts

Strange, the information I posted in my last message was obtained from the Apple support site http://C:\Mac\Documents\Hardware\Macintosh SE Power Supply Connector Pin Assignments.htm. I assume the Apple site is wrong then. Could an admin please edit my last post to remove this info / could someone confirm the validity of the Apple Guide to the Macintosh Hardware?

Sorry about the confusion.
