The Amiga 1000 was a ground-breaking computer of the 1980's. Many of us think it was far and above better than the other computers of that time. Unlike the 1980's era Macintosh, the Amiga was properly multitasking and had better multimedia, and of course it was a zillion times better than MS-DOS. But then in the 1990's Commodore Computer Corporation went out of business after promising several advanced Amiga systems. That left Amiga fans stuck and abandoned.
Fast forward over 20 years, and the Raspberry Pi is a flexible inexpensive Linux-based computer that's inspired all kinds of hacking projects. In this case, an Amiga emulator running on Raspberry Pi allows you to run AmigaDOS applications.
A speed test shows that with Amibian, a Raspberry Pi runs 250 times faster than an Amiga A600. Running various heavy-duty applications run faster than on an original Amiga. This is under an EMULATOR, since AmigaDOS of course was written for Motorola 68xxx processors while the Raspberry Pi is an ARM processor.
