That's probably correct. I was once inside a Xerox 1108 (it was running
interlisp-D when I finally got it to boot), and the CPU was 1 or 2 boards
of chips.

Unfortunately they were all house-coded (they had Xerox part numbers, not
ones I could identify), but I remember there being 4 40 pin devices which
I suspect were 2901 4bit bit-slice ALUs, and a lot of what looked like TTL
and probably some RAM as a control store around them.
