Computer collecting humor.

5 Nov 1997

...
   I have been
told that the CDC Cyber 70/170-series used a 60-bit wordlength. 
 Well, I am currently in a room full of 64 bitters (Alphas). Cray machines 
 as well...

 Many (all?) CDC machines are 60 bit machines. 
I have at home a memory bank from a CDC Cyber two-hundred-and-something 
(?) which is 18 bits wide.  I had always assumed that this was 16 bits 
plus two parity but it doesn't fit into 60 bits either way.  (Memory 
bank is huge quantities of 40ns and 45ns 64k x 1 static RAMs surface 
mounted on both sides of numerous daughter boards.  Each daughter board 
is 64k x 18 and they stack four deep all over the "mother board" of the 
bank.)  I always meant to use this in something, but somehow I never got 
around to it...

Philip.
