So how does the switch happen exactly? is it a keypress?

*Edit*
Nevermind I see how it works now...

[thesteve]

in short yes its a key press.
hold select during power up

Very nice steve!!   I'll be looking into getting some custom pbcs made to utilize that chip instead of the old 4551 design.

dont ground 2-5 as they are useful for the switchless version, and likely others.

They could be used to switch LEDs too couldn't they?

i just had a thought
the switchless circuit can use a switch without any mods whatsoever

So no more having to drill a hole into the system to have a region switch installed? All you would have to do is hold or not hold the select button during boot up? That is badass

You've got it keith!!  Steves design is fantastic!

Here's a little preview of the mod chip design so far... TINY TINY TINY!

Only 0.8" x 0.6" x 0.25"!

Wow, this is pretty awesome.

[thesteve]

see if you can get that on a 0.010 thick board

[BlueBMW]

0.062" is the cheapest solution.   0.03125" almost doubles the price.  0.010" is not available from this manufacturer.
