About the program of Kirk Meyer i am quite scpectic. The Z80 of the TI86 is
way inferior to the HP48 Saturn and it has taken several years for
programmers of the HP community to produce computer algebra softwares which
enable the HP48 to match or even overcome the TI89. Also these software
require much more memory than the TI86 has and they don't even provide 3D
graphic abilities of the TI-89. So i wonder how kirk Meyer would be able to
produce such a software ? Perhaps it would be possible on a TI86+ as Flash
application but on a TI-86 i very doubt.

The HP48GX is mostly faster than the TI89 for numeric computations. Try
numeric matrix computations and you will see that even the TI-86 blow the
TI89 in this areas(For instance try inversion,determinant and RREF on 10*10
matrix). It is really a shame to see a calculator so slow for number
crunching with such a C.P.U. Considering the speed of the HP interface,there
is a software called Meta-Kernel (but not freeware) which speeds it up to
until 100 times and which add so incredible apps. And the authors of this
software have been working on the new HP. I have heard that HP will show its
new calc the 05/21/1999 at Grenoble in France where HP France is based. I
will do all to be there !
