What kind of sucky homework assignment is this?

I wonder how many people will design an instruction set in their career.

Not to mention: a 16 bit machine with irregular instruction set.

 

I'm just coming from the thread with 150ns pipeline machine and wonder:

has this subforum fallen in a time warp? A worm hole?

How do these people of the past have an internet access to discuss with us?

 

This was technology when I was a student, and I have grey hair now.
