TI SR-50/51 AOS Possible?

[Gene]

Essentially, no.

The SR-50 was introduced on January 15, 1974 and the SR-51 in January of 1975.

The first ** AOS ** model, the SR-52, was not introduced until September 1975.

Those time gaps were immense in terms of continued progress in the calculator game.

Absolutely no way AOS could have been on the SR-50 or SR-51 when introduced. They were already pretty expensive (although cheaper than the HP's).
