MathTime PRO fonts for Y&Y?

[Doug Lind]

Has anyone successfully installed MathTime Professional fonts
for Y&Y TeX? If so, where did you buy them, and how did you get them
working?

     I currently have MathTime, but would like to upgrade
to the PRO fonts while staying with Y&Y. In particular, I don't want
to switch to PCTeX just to be able to use MathTimePRO.
