<Wow, you have a TMS1000 based micro? What the heck is it?
;)
Kids... TMS1000 was a 4bit single chip cpu from the 70s aand it was used to
make toys, games and even timers for microwaves. A system around that
chip might be a phone with memory and redial or a VCR timer. It did not
have an external address or data bus nor were there eprom versions.
I have numerous products with tms1000, COP4, uCOM4, uCOM75 series single
chip CPUs.
