Love it -- reminds me of a more focused Uplink.
Interestingly, there is a real world equivalent to the TIS architecture: the GA144[1] has lots of memory-constrained Forth cores with software defined I/O between them.
There's nothing in the TIS-100 architecture that is unique or unheard of, just things that are left out of it.
That said, if you liked Uplink you should try Hacker: Evolution and HackNet.
