Good news, there is a good ole fashioned way to connect amiga to pc, and thats with an old but of hardware, called parnet, and the software is on amiserve.
You might be able to get a lead from amigakit.com
Not many amiga`s will play all games.
A500+ won`t play all A500. Same as the A600.
The machine htat played nearly all non aga games would be a kick 1.3 a500 with 1meg.
If you want to play aga games, then a1200 is really the only viable option.
Both machines are cheep on ebay or car boots.
Incidently i got a kick 1.3 a500 boxed for sale, was gona put it on ebay next week.
Make me an offer if you like. don`t 4get the postage. i`d have to get it weighed to find a price on that.
Hope this helps mucker :lotsacoffee:
