Re: TI-H: ti-turbo



Yes, I've also burned a small hole in my ribbon cable, but it didn't get to
any of the wires, so I was lucky.  Also, the part about losing
lines...that's only if you mishandle the LCD.  My friend's is like that
only because he dropped the calc once too many times.  I repaired it just
by resealing the connections between the rubber strips and the glass panel
and it worked fine again.  Just be sure to be careful with the LCD.

it

: out the capicitor by over-heating it, and just solder a new 33pf
capicitor
: to one end of the old one.  Be carefull, it takes a lot of heat but it's
: pretty easy to burn out a surface mount capacitor.  Then you use the
: schematic for the switch and the 1pf cap in the accel85.txt file.
