Excellent video, very interesting how close the 1970's microcontroller is to what we still have today (at the low end).
Funny, a propos that feature in the TMS1100 - the "Instruction Programmable Logic Array" - it seems that a variation of that idea is making a comeback, in the latest Microchip/AVR chips.
The modern version is called "Configurable Custom Logic" and is of course much more flexible than the TMS1100 in every way, but the basic idea of implementing logic that need no code or supervision from the CPU core was definitely present already in the 1970's!
Apparently there is a new Arduino on the way that features a chip with this capability, so we'll all be able to have a play.
