I had an A500 too! Great machine. Bought a 52MB GVP hard disk for it (which was actually quite quiet!) and ugpraded to 3MB of RAM. Then bought the A1200 with a 120MB hard disk and 2MB of RAM.
Sadly I sold them both to fund the upgrade of my 386 to a 486. (I was still at school so didn't have much spare cash... Working Saturdays in a cafe washing up didn't pay all that well!)
But now I have another A500 (still looking for a hard disk) and another A1200, all courtesy of Ebay. In fact, I bought an A1200 with 030 accelerator, CDROM and a box load of CDs for £30 in a car boot sale about two years ago. I sold it a week later on Ebay for nearly £200!!
My fav games on the Amiga: Xenon 2, Megalomania, F/A-18 Interceptor, Silent Service II.
BTW, WinUAE is the defacto standard emulator for Amigas on the PC. It's pretty good and runs most stuff... And it all loads much quicker than it did on the Amigas.
