 Sorry, I should have summarized what I know. 
 The Itaniums also have that format I believe., 
 As do some old Motorola chipsets although they the Motorola variant
which  
 is 96 bits wide (with 16 unused bits in the middle from memory) 
 I was just curious if anybody has designed and built a chipset in
the  
 last 20 decades which used the 80-bit extended format. 
 I have never seen a 44-bit extended format in my life.
