Odd questions, perhaps:
Was there ever a commercial 32-bit machine built with 2901s? Other bit
slice devices?
What is the longest word length machines done in bit-slice?
Is there a practical limit to the word length of a 2901-based machine?

Sure! The VAX 11/730 and 11/725 were 2901-based 32-bit machines.

ISTR, the Chyron character generators were bit slice, 4 each of 4 bit
chips. They were AMD a20??, don't remember the exact number right now.

There was an outfit called Systems Engineering that built a 32-bit CPU using
boards they had made here in Denver by the guy who built my PCB's. Theirs was
built with standard "family logic" though rather than with bit-slice
components. They used BIG boards, BTW.

The Symbolics 3640 I saw used AMD bit slice chips. I can not
remember
what type exactly, but definitely AMD stuff. The word size is 32 (or
36?) bit. You may have a look at
