 As others have pointed out the 78xx and 79xx regulators have different 
< pinout also 

[ ... cut ... ] 

I finally got frustrated and blew the damn regulator up. I never seen
something fly that far. Luckily I used one of them heat sinks. Damn thing
gets hot as hell. Must have a fuse inside of it - I wish I could look
inside
the case (I dunno all the names for cases, it was probably made of
plastic).
I just was doing stupid experiments. (I thought that it was a negative
voltage regulator so I could flip the capacitors around - it seemed to
work
but that fuse finally gave way.) I was getting nasty spikes and was
annoyed.
Thanks all, for the replies - it's nice to talk to people sometimes...

Anywayz...

< the TL431 is an adjustable zener not a voltage regulator. 

How can a zener be adjustable aside of external components and such? Coils
would be inductive (?) and probably dangerous unless encased? Is it like a
crystal of sorts? What's in a zener and them blue diodes (the ``fast
switching
diodes'')?

I'd look it up but I'm re-compiling x at the moment, funny thing that xrx
is, and bugging me and I absolutely hate dri/opengl/nvidia/intel91xx at
the
moment. dunno what's so bad about CRTs... damn funky pixman-1 and mmx.
(anyone know what the hell is mmx while I'm -a- asking?)

thanks, for the relief...
