Re: What part of a fried GS is salvageable?

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

Get my BUGG-POWER unit, dont do disasterous trial-and-error like
Supertimer just did.

I've shipped 167 units since April 1996.  Every single unit is pre-tested
on my OWN Apples prior to shipping, and I've not yet fried any of my
motherboards!   For tower-izing a IIgs,   specify how long the
cable-length
you want. 


150 watts  $27, 200 watts   $30., 300 watts, $40.

Add $5 for shipping of one unit, or $9 if two units in same carton.

Add $4 for Y-Cable (You can run TWO APPLES concurrently with one power
unit.

Specify whether IIe plug or IIgs plug is needed.  (Same price).

:      Aha! Another "power user"! (There is nothin quite like the feeling
: you get when you notice you've just fried a board with reversed power
: leads.)

:      One idea is to remove the removable IC's (like the 65C816, VGC, and
: Ensoniq) and see whether or not the Power Supply still thinks there's a
: short when you switch it ON (with + connected to +, etc.).

:      If the PS doesn't start clicking and the voltages are correct,
: there is a chance that one or more of the pulled IC's failed to a short
: condition quickly enough to prevent other components from being damaged.
: You could, then, try inserting the pulled IC's one at a time and turning
: ON power. When the PS starts clicking, you'll know you've found a blown
: IC. The IC's which do not short the PS _may_ be okay.

:      If the board has a short even with all pullable IC's pulled, your
: best bet may be to just put the pulled IC's in an anti-static bag and
: the motherboard in your boards bin until such time as you absolutely
: need to try using something from the fried board as a replacement.
