What is amiga?

god , didn´t think of them for years. a friend of mine has about 5 or 6 "breadboxes" at home. reaching from commodore 64 up to amiga 500.the amiga 500 had some sort of OS named "workbench" wich was loaded from two 5,25"s after switching the machine on. he also has a datasette recorder wich stores data onto normal audio cassettes. that schtuff was great fun. technically, the amigas were great machines. and u can use old amiga monitors as very good tv sets  ´cause they use comosite video signals and have tremendous picture quality.
