I came across a cheap 1st-gen TI-Nspire CAS this past weekend (the kind with the click pad), which only supports AAA batteries. It got me thinking, what other CAS models (any brand) are out there that don't rely on a proprietary rechargeable battery pack? I can think of a few, but there must be other ones.
TI-92/92+
TI-89/89 Titanium
TI-Nspire CAS Click Pad or Touch Pad
Casio Algebra FX
HP 49G/49G+/50G (I think the same or similar software is available for the 48)
Wasn't there a Derive card for the HP palmtops?
