We are having trouble getting MetaFont to do anything useful on our
CDC 4680.  I'm using the TeX3.14 distribution and give the following
command

cmmf '\mode=localfont; mag=magstep(0);' input cmr10

On a Sun4 machine it works just fine, but on the CDC/MIPS box
(compiled from the same source, sharing the same INPUTS area) I get
the following (unbounded black) error

This is METAFONT, C Version 2.7 (base=cmbase 92.12.24)  1 JAN 1993 16:09

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.

I have no idea where to start looking for this problem, but I'm pretty
sure that this isn't really a capacity problem.  I'd be grateful for
any advice.  Does anyone else have MF working on a MIPS (RISC/OS) or
CDC (EP/IX) machine?
