TI SR-50/51 AOS Possible?

[Maximilian Hohmann]

Hello!

Apart from the question "was AOS a technical possibility in 1974?" another question comes to mind: "was the concept of AOS already around in 1974?". Or did AOS evolve in parallel with the hardware, possibly as a request of calculator testers and users. I do not know if there were desktop calculators before the SR-52 that implemented AOS. A bit like RPL which was invented together with the first RPL calculator.
