With exraordinary simple thinking one can easy develop

stages of an execution pipline for this opcode. Staight

reading the opcodes is like reading a step by step instruction
to build the CPU.
Ok, maybe I'm overemphasing, but I love this structure.
I did almost any microprocessor (from 1802 to 9900 and Z80)
in the past 20 years, and some of the bigger architectures,
but none equals the /370.
So, if you want to have fun, take the OP-Code table and
solve the puzzle - or just keep the manual for 'real world'
tasks, since this Assm is still valid for IBM (and compatible)
Mainframes. I bet your taxes are calculated on one of 'em.
Well it's unlikely anyone would let me anywhere near a mainframe but
from your description it sounds like it would be good
just to study and
learn from.
