Don't ask why I want to build one of these.. I don't even know! It's not like a 32B memory would be very useful these days.. :
I want to learn (specially how to use an opamp), and I guess I am just drawn to awesome old-school computer stuff. You know, old-school always gives the most geek-cred.
LOL, that's so cool. Thanks for the explanation on how it all works--I learned something.
I assume there must be plenty of op-amp tutorials out there... (You couldn't get away with a simple high-gain transistor? Or using the ADC?)
