Programmable Calculators: The First Generation

[Gene]

TI gave full acknowledgement and press to those registers 98 and 99 in press and in materials such as the TI PPX Newsletter.

I don't know about the manual (most of mine do not have that info but later revisions might).

For 28 registers, I presume that would require manual RCL and STO into 70, 71, 72, up to 97 and then writing a card.

I believe under **program control** using R98 and R99, all 20 regular data registers were able to be read / written from a card.

Very neat.
