Is it possible to program my bs2p to communicate with my TI-89? I want to be
able to store calculator programs onto my stampmem modules using my basic
stamp. If this is a stupid idea, I apologize.

calculators have always been plagued with very little memory, that is..
if you are using your calculator for more than just calculating d;D
it should be relatively easy if you know the protocol that the TI's
use...
not sure if you've been there, but www.ticalc.org or www.ti-calc.org
(something to that effect) has information on how each of the TI's
communicate.. it's pretty easy...
from what i remember...
there are 3 wires in the serial cable, one is ground, and 2 are for
sending data..
if one of the wires goes low, you have to pull the other one low, and
when the first wire goes high again, you have received a binary 1...
receiving a binary 0 is the same but the same events occur on the
opposite data lines... ie.. the "other" wire goes low.......
that explanation was probably more confusing than helpful, but the
website i mentioned has much better info on the link protocol

Z-80 assembly and 180k of memory. With a graphic display and a keypad
on the TI, it makes for a cheap add on to the basic stamp. Plus, it
does any kind of math!
