I used ot know of a website that would allow you to do basic things on a variety of operating system, both old and new. It was basically a simulation that would allow you to view options, like control panel, or in mac the different utilities and navigate Thornton's, but you would not actually be able to do anything. This would be really helpful for a training class that i have that will need to know to navigate different operating systems. This was an online simulator that if i memory serves had all the way back to windows 3.1 and mac os 7. we would need it for 2000 and above and OSX and above. thank you in advance.
