Re: TI-H: RE:IRLink Schematics
hello, the ti-92 plus module is comeing in a month or two. it will add
another 128 user memory.(now i read something about it haveing 500k user
mem?...someone look at Ti website) on top of the 92's 60k now...
thats pleanty of memory. so maybee makeing it for 92's is the most
feasable anyway. and it also has a query key board, and unless someone
can figure out how to connect a keyboard to the Ti-8x series it wouldent
be very practical to use them for internet.
thats just my opinion.
sorry for the spelling , im in a hurry gota leave in 10 minuts.
