Does anyone have information / know where I could find
information on
building a computer using 2901's? I know they were fairly common and
I have (I'm almost positive) a few of the bare chips laying around
home.
Find an old (early 80s) copy of the amd or motorola data books.
These are bipolar 4 bit slices and can be used to make a fairly fast
cpu (10mhz) of variying designs from 4 bit to over 64 bits. Warning
microcoding can be habit forming. You will also want 2909/10/11 microcode
sequencer chips. Those are less common.
It's rather fun designing a cpu to your specs, hten of course you'll write
all the other code too as it's one up design.
