Hi oneartist,
I currently use Workspace 5, so you might find it hard to get hold of WS 2, as your talking about an application designed for DOS systems.
I used WS 4 as part of my robotics curriculum and it proved beneficial.
On the market are alot of simulation packages available, all on...
Can explain what exactly you need? Simulation purposes only? Offline programming???
I work for a robotic software company, and our software might be able to help you out.
