Given that both use a Toshiba processor that is probably not a surprise. It appears that this LCD was commonly used at that time.

Thanks for sharing your pictures. I always enjoy them.

The TI-25 is a neat machine as well. I'm waiting to see one in my local sources (Portugal) to grab one for my collection.

Thank you for sharing your knowledge here on calculator algorithms and mathematics.
I keep reading and learning (and I have so much to learn in these areas).
