Thanks.
Maybe this was a popular thing to do in the mid-1980s? The
undergraduate computer architecture course (1983 I think, maybe 1984)
I took basically went from gates to a PDP-8-like CPU over the course
of the semester. Somewhere at the beginning I think we spent a
half-hour on the fact that there are different logic families, but we
never touched on that again. (This was a Computer Science course,
Real Hardware seemed to be the province of the Electrical Engineering
department.)
Talking of 16 bit extensions to the PDP-8, that is
what the HP-2116A
appears to be, anyone konw that processor?
By manuals only I'm afraid, and I spent more time fascinated by the
possibilities of user-developed microcode in the 2100A. The 2116A is
entirely hardwired, with two accumulators, 16-bit word, 32KW memory I
think. Oh, and stable across the same environmental conditions as
other HP instrumentation.
I suggest you webulate over to www.chac.org and look for the
plain-text versions of Engine 2.3 and 2.4. You want to read the
interviews with Barney Oliver and Joe Schoendorf in those issues.
