Has anyone else noticed inconsistencies in the way Row 40 of the passthru slots of cards for SE/30/IIsi are implemented? Are there other instances?
-12V at A40 - has connection inconsistencies in implementation?
_____ OK ___ Asante NIC
_____ NC ___ RCPII/IIsi Pivot VidCard
_____ NC ___ SuperMac RA Adapter
-5V at B40 - doesn't appear to be connected on any of these passthru slots? Very strange.
_____ NC ___ Asante NIC
_____ NC ___ RCPII/IIsi Pivot VidCard
_____ NC ___ SuperMac RA Adapter
+12V at C40 - connection is consistent.
_____ OK ___ Asante NIC
_____ OK ___ RCPII/IIsi Pivot VidCard
_____ OK ___ SuperMac RA Adapter
Why would the -5V lines be NC on on all three cards?
Why might the -12V connection be unimplemented on the Pivot card.
Why are the two Video related cards differentiated from the NIC. very curious.
Need to check my other Asante NICS, Radius Pivots andSuperMac RA adapter for IIsi. Very strange? :huh:

I wouldn't worry about those too much...
Most cards they had in mind to be used on the passthrough probably didn't need those special voltages anyways.
Only use of +12V that I have seen yet is on various ethernet transceivers built into the breakout board of NICs.

I figured +12V is on the LC Slot for the FDD on the end of the IIe card's cable, but it's OK on all cards tested anyway.
Figured the VidCard thing for the adapter, but not passing it through on the Pivot seems very strange.
No -5V passthru connection on any of the cards sticks out like a sore thumb to me.

-5V is rarely used by expansion cards. The host's power supply might not have it available either.

I have a few machines which are running off of +5 and +12 volts. The only thing that doesn't work is the sound.
