NIGHT STALKER
I'm looking at the derriere of my SuperIIsiHack™ and deciding that I'm not going to chop a big rectangular air vent outta' the poor thing as originally planned.
I don't give a rodent's rump about keeping the tail end of my IIsi stealth, I'm going to have t hack way too many I/O connectors onto it for that.
HOWEVER:
I'd really like to hack the replacement ATX PSU to make use of the existing circuit, and switching PSU connectors. These are mounted to the back of the empty, original IIsi PSU's sheet metal that will be acting as a support for the long thin ATX replacement. There's even a handy femal connector terminating all the wires for the AC connector block. The matching, keyed 6 pin header will be easily harvested from the DOA IIsi PSU's PCB.
OBSERVATIONS:
It looks like:
PIN #1 AC-Out (Monitor) Connector's Hot wire is fed back from the Circuit Board (relay/solenoid?).
PIN #2 N.C. (with wider spacing for keying the connection)
PIN #3 Neutral Wire passing through/around Ferrite Ring from AC_In
PIN #4 N.C.
PIN #5 Hot Wire running from AC-In at solder junction with wire to PIN #6
PIN #6 Hot Wire passing through/around Ferrite Ring aside Neutral from AC_In
The hot wire for the AC-Out on PIN #6 appears to originate from a solenoid and is fused before making its way back to the "Monitor Plug."
QUESTION:
Can such a Relay/Solenoid Setup (at least I think that's what is going on) and Fuse be safely added in between the ATX PSU and the original IIsi (or other Mac PSU's Bits) in order to retain the switching function for powering up the Monitor/Whatever?
