On the TI side,
I have the "TI-52 scientific". Does all the
hex/dec/oct/bin conversions and some other stuff. VERY happy with it.
Since I bought it (10-15 (?) years ago) didn't change the battery.
At first I thought you were referring to the TI SR-52 programmable
calculator from the mid-1970s, which didn't have such things. But
on reading the rest of your message I realize that the TI-52 must be a
different calculator, presumably with an LCD display.
Yes. It has an LCD display.
