MAC emulation?

[Tom Uban]

I have a Powerbook 150 running System 7.? and only really use it for
one purpose, which is to run the old MOTU FreeStyle and FreeMIDI tools.
My question is if there is an emulation environment available for a PC
which provides enough facility to run System 7 (or possibly 8) and these
applications which need to talk MIDI via one of the serial ports and
a MIDI interface?
