Re: 48gii on USB??? Message #7 Posted by David Hayden on 21 Nov 2011, 5:01 p.m., in response to message #2 by Thomas Chrapkiewicz
There are a few ways to distinguish the two versions.
If they are in the retail package, check the writing on the front of the package to see if it says it supports USB. You can also check to see if there are 3 batteries or 4 in the package.
If the unit is out of the package, just look at the top of the calculator to see if there is one connector (serial, old version) or two (serial and USB, new version).
The old versions are sometimes available new on TAS for around $60 (or they used to be several months ago). To me, it's a very inexpensive way to get a really first class calculator.
