Re: TI-H: Turbo ti-85 for electronic newbie

Just go like this:
+-----------Z00X1 (where X1 is connected to the board and a wire is at Z
and | Z00X is the original 33pf capacitor at C9)
|
H--------------X2 (where H is a 3 contact swtich and the wire to X2 is
connected | to the center contact; X2 is connected to the other pad on
the | board)
|
+-----------Z00X1 (where X1 is connected to the same place the 33pf
capacitor is connected to (at X1) and Z is connected to the wire
connected to the other pad on the switch. This capacitor is to be 1pf
and does not have to be surface mount; if it were a ceramic disc
capacitor, you could have the wire extending from Z just be the
capacitor's lead itself; just insulate it with some glue gun glue or
something)
Left up to me, I'd skip the 1pf capacitor part and leave it empty; you
could even use a 2 contact switch (on and off) for that purpose and it
would be easier. Hope this helps!

: Anybody willing to wip up a diagram to make a switch for a turbo ti-85?
: I got the one from ti-calc, but I'm kinda a newbie at this electronics
: stuff and couldn't make out the diagram either. How does this all work
: anyhow (the turbo without taking out the C9 completely)?
