Programming a Kenwood TK-3101 on a too quick machine

I have managed to get the typical Kenwood software KPG54D and KPG48D for their TK-3101 transceiver on one of the fastest Apple MacBook Pro‘s currently on the market, running OSX Lion, using VMWare Fusion, Windows XP and DOSBox. This might also work on any other virtualization environment, such as Parallels or VirtualBox, and even natively on other Windows versions.
