Amiga - don't know. Probably only with an emulator.
As to internet access, keep it online for a few days if possible, just to benchmark and get on the list. I have laptops folding that don't get on the internet very often and I have switched them all to a console version that uploads in batches.
One of my laptops started processing work units slower.
Looking at the hidden processes running after a restart shows FahCore_82.exe running and I have not yet launched the client. CPU usage 98%
Launching the client the console opens and starts processing ...
Looking at the hidden stuff again shows 2 Cores running @ 49%
I'm thinking of trashing one of them but hate to loose the WU.
Any thots? Running XP
