EPROM simulator eases firmware development

Static Random Access Memory was an expensive device in 1980. And so was the EPROM (erasable, programmable read-only memory). I considered EPROM to be "very" expensive since the programming-erase cycle took a lot of my time and they usually went kaputt within a few cycle of programming. Now with the EPROM simulator, I could quickly change my code, reprogram and test the microprocessor system as frequent as I like, and very efficiently.

Although nobody claimed to be the first designer of this simulator, I considered the design and publication to be the very early one, if not the first in the world.

This article received the "Design of the year" award from the publisher, and I got a Texas Instrument TI-53 Calculator for the prize from TI.
