I have looked at an IBM/320 and an HP/720 for possible purchase.
For reasons of FORTRAN numbercrunching speed, I am leaning toward
the HP right now. For my programs (molecular dynamics) the HP
ran 1.6 faster than IBM. By the way, the -O option in HP f77
altered the result of one of my subroutines. I had to be content
with the +O1 for that routine.
 
In any case, what I would like to know is whether a 16 Mb RAM
420 Mb disk, 19 in color and DAT drive would all work together
under HP-UX... mainly Vue and the 16 Mb. Naturally the demo machine
I had here was with 32 Mb RAM and that worked fine. 
 
Bottom line: does HP-Vue compete with background FORTRAN memory-resident
 numbercrunching jobs? Does it WIN if RAM is 16 Mb?  I am sure I 
cannot afford the 32 Mb RAM without sacrificing the color monitor. 
 
Any remarks stemming from experience will be appreciated.
