My collection of early computer manuals includes Brinch
Hansen's manual
for the RC 4000, which stands out for its precise description of the
CPU logic--in Algol 60! It's the only manual I have seen that offers a
good-to-the-last-bit formal description of the hardware.
The book "A Programming Language" by Kenneth Iverson included a formal
description of the IBM 7090 in Iverson Notation (now APL). I believe that
is the first formal description of any computer. The success of that led
IBM to include a formal description of the System/360 architecture in the
IBM Systems Journal issue introducing the S/360.
I've been told that IBM has since regretted that decision since it opened
the way for other manufacturers to clone the S/360.

Blaauw & Brooks wrote a massive tome describing all manners of
machines in APL ("Computer Architecture: Concepts and Evolution",
A-W). I am not familiar with it. Is anyone on the list familiar with
it?

Interesting!

I think Fujitsu were the biggest clones, followed by Hitachi? And I seem
to recall at least one Russian clone...

The ES EVM (ЕС ЭВМ)series. At IIT Bombay we had a model EC-1030.
