Zedsdead – what do you NEED an emulator for? Most people I know who have used emulators do so for ‘fun’ or some weird geeky obsession. If you are not an uber-geek, then I can’t imagine “needing” an emulator.
The only possible reason I can imagine is someone wrote some code 20+ years ago which you now need to run. If you have the source code its probably easier to port this into a 21st century language / platform than get it to work on an emulator. If you don’t have the source code, good luck getting it onto the emulator, and I’d spend my time looking to see if there is an off the shelf tool available to do what you want – very few problems which were being solved in those days are unique…
