I need to generate some sensible eqn output on a Diablo 630.  Can this 
even be done?  I'm using "neqn" which may or may not be standard System III
or System V, I don't know. I'm using INTERACTIVE's "IN/ix" port.  The manual
page says neqn is for nroff and eqn is for troff.  Other documents indicate
that neqn works on some devices, but the 630 is not mentioned.

Actually, I get something relatively useful for output as long as the equation
doesn't use greek letters.  Square roots are OK, and a limit looks pretty
good, comparatively speaking.  Greek characters don't generate - and I don't
expect them to on my current printwheel.  If I want a Sigma, I get a "R".  
Pi comes out as a "C", Rho as a "K".  The Integral sign is a "^".  Each of
these is preceeded with a control-N which is the ASCII "so" (shift out?)

Now, what should I expect to happen?  Are there some printers that will stop
and allow you to change printwheels?  I looked in a printwheel catalog ate
the "general scientific" wheel which has everything I need.  However, the
daisy petals don't match.  I.e., the "R" isn't the same petal position as
the Sigma.  Is the control-N an escape for some printers/terminals that
does something useful?

Any suggestions?
