Gregory's Serveri guess i should write a program. there is an assembler that supports this architecture (http://john.ccac.rwth-aachen.de:8000/as/) but i'll get that working later. for now i will just write it in machine code.

 the bus timing looks like this. the top trace is the clock, then there is NADS, IDS (input data strobe), and finally the F11 output (which is driving the LED). i cheated and slowed the clock down for the video so you could see it blink. |
and we have a blinking LED! this is being driven from one of the 4 flag outputs on the CPU.
