Rado has written a short review about this PC emulator for those who still did not check out the free demo. Also he has interviewed Reza Malekzadeh, the director of marketing at VMware. And if this does not push tears in your eyes, you can use them to do some real work as well. At that point, none really thinks of ZX Spectrum or Commodore 64 emulators. At that time, it was a free beta version, and it did a remarkably good job.
Executor is fine piece of software, but it still needs some improvements.
I was wrong. It was just too easy to setup the beta and install Windows NT 4.0 Server on a disk image. Scrolling and mouse movements were not quite smooth. VMware is not just an emulator. This, however, requires some modifications to get everything to act as usual.
