Apple IIgs upgrades

[Jeff Tacy <slam@home.com>]

Hi all, does anyone here remember the Mac SE upgrade kit that included
18-ga wire, a bunch of new caps and other fun stuff, that increased the
computer's amperage and allowed more upgrades, also fixed many problems?
Is there anything like this for the Apple IIgs that someone has
constructed? Also, wouldn't it be possible to use an IBM AT-type power
supply with a different connector in a GS? If so, are there plans
anywhere? Thanks all!
