Re: Question on the 83 [Re: TI-H: TI-85 Schematic]


I think that my chips (25) will come in by friday.  If so, I will be
selling them.

PS.  Rates of above 9600 kill the calc, and sometimes even 9600 can.  It
will have baud rates of 2400, 4800, and 9600 just because some calcs (82/3)
can't handle 9600.  The 92 how ever could handle a whole lot more.
