Hej allesammen;
What's a 'bit slice'? Are they served with a twist of lemon?
I suppose a better way of asking that is how is a 'bit sliced' processor
or ALU differentiated from a 'normal' one?
ok

I'm no architect (but I play one on TV), but bit-sliced processors can be
cascaded to build up larger-word machines. E.g., you can take two 4-bit
ALU slices and make an 8-bitter.
BTW, I mentioned a while back that I wrote a simulation of a PDP-8 built
from 2901's. I finally found the source code for
everything but the
assembler (but I did find a grammar spec). It's not in good
enough shape
to "publish", and I don't plan to spend the time to get it there, but if
anybody wants a copy, let me know and I'll send you source. (It's
curses-based, and should run fine on any Unix or DOS box).
