Re: [NTLK] Overclock - Reset after switch?

Hi Chris,

I haven't found it necessary to reset after every speed change. However, I
am careful to only shift speeds when there is nothing but the backdrop open.
It might be a little safer to reset when you change speeds. I haven't had
any trouble though with lost data or anything.

As Ed says on his overclock page, a great source for teeny switches is dead
PCMCIA Flash cards. The write-protect switch in there is perfect. I used
one of these when I redid the overclock. If you don't have any dead PCMCIA
cards to scavenge parts from, you can get surface-mount switches from
DigiKey or Mouser or other on-line electronics supply stores.

Acid-core solder should never *Never* be used for electronics. It's for
plumbing I think. The acid will eat away at the circuitry and cause damage.
Rosin-core is for electronics.
