Even fairly old versions require a maths copro. Some of my then-colleagues at
Acorn Computers were involved in negotiations with Autodesk in 1987, to get it
ported to the ARM architecture. AD ported Autosketch quite quickly, because it
doesn't need a maths copro, but they refused to port AutoCad, because they
insisted a maths coprocessor was essential (despite the fact that the software
routines available outperformed some contemporary maths processors).
