Oh THAT sounds like fun!
I worked on a
commercial (well, "commercial academic", a NASA-funded
project at a university) design that used an Am2910 microsequencer, and
that got me interested in 2900s. Well, that and seeing rows of them on
the FP11-A in my PDP-11/34, and several third-party disk and tape
controllers. ;) I've always wanted to do an Am2900-based design, and I
will if I can ever get some free time.
I do have an Am2901 eval board which is pretty neat.
I have a S100 board that is said to be a math processor board
that has a single 2901 on it. I have the manual as well. My Nicolet digital averager scope has several 2901s
in it.
They used these just about anywhere one needed a little
more horse power.
Yep. Amazingly flexible chips. Even the CPU of the KS10
(DECsystem-2020) is built around them. I think the VAX-11/730 CPU is as
well, if I recall correctly.
