Re: IBM Power Supply to IIe or IIgs : tech questions

[buggie@musca.unm.edu (stephen e buggie)]

Thanks for the comments.   I have found a supplier for the IIgs 
motherboard connector.  I have ordered big supplies of copper AWS-18 600v 
insulated wires, cord ties, shrink-tubing, etc.  I still need to get the 
IIE MOTHERBOARD CONNECTOR so if anyone knows of a source for those, tell me.

Apprciate the advice on the +5v lines.  Yes, I will group two of those 
lines on the IBM power supply so that full amperage will be gained.  
Coper wire will be best for carrying all the power available.

BTW, I have successfully installed  150 watt IBM power supply on my 
"flagship IIe," and it works great.  No freeze-ups since installing it 3 
weeks ago.

Hey I am selling my so-called AE "heavy-duty" power supply for IIe; 
$30.00 plus shipping.   Anyone want it?

: In all of the power supplies I have seen, and I've see a lot, like
: voltages all go to the same connector _inside_ the power supply.  So,
: yes.  All the +12V that go to each pin come from the same part of the
: power supply and they are not separate windings.

: Usually the +5v has two or more of the pins.  +5v is used the most and is
: usually the part of the Apple ][ power supplies that burn out.  I'd
: connect them both if you use the connector.  I'd use a connector simple
: because it will make it easier in the future to deal with.

: On the other hand, if your Apple ]['s work on the 70W power supplies, but
: fail only once in a while, chances are you are just pressing the limits. 
: Maybe drawing between 60-70W, which creates heat, heat breaks down the
: power supply and therefore it fails.  Putting the 150 Watt P/S on there
: will barely make it sweat even if you add a few hard drives off that power
: supply.


: No, grouping the wires will have little effect.  You might concider
: grouping the two +5V wires together if you are really concerned about it,
: but I really doubt it is nessessary.  For one thing, the wires are usually
: 12,14, or 18 gauge and are plenty sizable to handle a couple amps, which
: is about all you are really drawing.
