The idea for this page is, I admit, a rip-off of this page: The
Hardware of a TI-89 which has long since been deleted (but I've linked to it
on WayBackMachine so that, hopefully, you
can still see it).
Since I haven't actually stolen any of the
information from that page you will still need to go there, or elsewhere, for most of the
interesting detail about TI-89, TI-92+ and Voyage 200 hardware.
However I have something which isn't on that page -- photos of the inside of
my Voyage 200...
