Enterprise Expansion Connector
« on: 2011.January.17. 14:03:10 »
Zozo ( or anyone )

Can you tell me if the edge connector supplies a +5v ? 

I have noticed that the expansion module converts the +9v (A/B)33 down to
+5v on (a/B)4.  I was not sure if the Enterprise had +5v on these anyway or
I had misunderstood a question from some time ago.


Thanks

Russ P.

No, on the machine is only +9V at the A33/B33 pins. The System Bus Bridge have a 7805 which is make a +5V at the A4/B4 pins (these pins on the machine is a empty).
