The 40E had microcode whilst the vanilla 40 didn't?  I thought only the 60 
was micro-programmable; I never did get around to implementing CSV/CRET on 
our 60 (Digital had a bunch of them when a contract with a publishing 
house fell through).

Reminds me of the time when I used 2-char constants in case statements; my 
boss yelled at me.
