To add on to this, I am currently working on a project where the only source of persistent storage is [0], which offers 64B of general purpose SRAM. It is a $0.70 low power clock with built in support for battery backup. Our main processor has more memory, but that goes away when we loose main power. Still, 64B should be enough for everyone.

I wrote a thing way back when, probably a TI chip or something, which had like 300ish? bytes of memory. It got commands from a serial in (which was a bluetooth device, commands were sent from a java application on a laptop), the commands were a simple self-made thing which was a command (two numbers) and an argument (like, "set speed to 10"). That then controlled a PWM for the engine and things like that. RC boat with a few hundred bytes of memory.
I'm reinventing all that now with using raspberry pi's and arduinos and such. I just got an EPC32, which is a $5 device that should have wifi and bluetooth and such built in already.
