I think Robert is correct, Semour b= uilt the CDC machines after he
left ERA, which (I think) went on to beco= me UNIVAC.  

The CDC "factory" where the 1604 was built was lo= cated at 501 Park
Avenue in Minneapolis.  An interesting numerolog= ic fact. 

For what little it's worth, I was actually in that b= uilding and used a CDC
160  computer to do real physics.  The = 160 was a true desktop computer
(being roughly the size of a desk) and h= ad 4096 12 bit words.  The Fortran 60
compiler was a three pass com= piler.  Each pass of the compiler was
loaded in from punched paper= tape and the intermediate pass-to-pass
data was also on punch paper ta= pe.

Later on, I (and another physics grad student and a senior compu= ter center
person)  heavily modified the original CDC 1604 Fortran= compiler for the 1604
to produce the U. of Minnesota Fortran compiler. =   A fast compiler with
excellent (for the times) diagnostics that g= enerated near perfect code if
you didn't use DO loops.  Being a lin= e at a time compiler it was a little
weak on constructs that extended ov= er more than one line.
