ty^^ That will fill a medium book. Intel put out a good one on the 386x process and code that is still relevant for 32bit systems. Sorry I don't remember the name but it had 386 in the title.

Try the web at Intel. They used to have extensive files on such for the public.

I believe you are correct. Only ten years Learned so much and maybe forgot more.

Thanks you wouldn't have an ISBN by chance?

I would look at the data sheet for a simple micro such as a Z80 8 bit not an 8080 as that uses a multiplex bus...

Basically the sequence is simply, set up pattern on the address bus then read data on the data bus, the control bus is just used to enable chips, read interrupts, etc...

I should have thought of that, much easier to learn that way. I learned it the other way around due to work.
