Re: The 2e power supply

["BLuRry" <brendan.robert@gmail.com>]

The quickest/easiest thing to do is to get an ATX power supply and
connect the outputs appropriately to the //e power connector on the
motherboard. (total cost $0 - $15 depending on if you have a pc you
don't care about lying around -- make sure it has -12v and -5v outputs,
some don't)  Since the ATX is too big for the //e case, your better bet
is the GSE Reactive replacement power supply -- which is $60 but is
well designed for the // form factor.

As far as schematics and so on, never found any.  But I have a working
//e power supply (120v US) if you want me to open it up and take a few
hires pics of it.
