(j3.2006) Question about DIM

[Dick Hendrickson]

I'm pretty sure I started in the spring/summer of 1962.  Used a Control
Data 160 desktop computer (actually, it was the whole desk.)  It had 4096
words of 12 bit memory and a 6.4 Microsecond cycle time.  I started in
assembly language, but within the year CDC came out with a Fortran
compiler.  A three pass compiler (it fit on 3 rolls of paper tape) and it
used paper tape to pass intermediate results from pass to pass.  It was
small, but people did real physics on it
