Yes, it would.

bshoring;

The TI SR-52 could read and write cards too. It also fit in the PC 100 cradle.

There are great pictures of both on Joerg Woerner's "Datamath" site. Unfortunately; the 52 and the 58/59 series are so similar you probably won't remember which one you saw 34 years ago :-(

I have one and it was impressive but since it's not RPN it doesn't see much use.

Note to Benoit: I did my taxes on the RPN 1200 ! --- so cheers for TI RPN.
