According to my paper copy of the UV7 manual, it is possible to run V7 on
a machine with no floating point, and the main problem is when compiling
say numeric code. There's a short section on how to do a build if you
don't have fp (like me on my 11/34). I think the V7 manual may well be
on line; but if not I can do a Xerox of this if it would be useful,
