The Amiga 500, also known as the A500, was the first popular version of the Amiga home computer, "redefining the home computer market and making so-called luxury features such as multitasking and colour a standard long before Microsoft or Apple sold these to the masses."
Hard-drive equipped versions were labeled "A2500HD" Amiga 1500: 1990–1991 68000 1 MB 1.3 3.9 / 3.2 UK only, variant of A2000 with two floppy drives and no HDD. This version originated with CBM UK Marketing who found it necessary to distinguish the floppy-only version from the A2000 with the general public. Amiga CDTV: 1991–1992 68000 1 MB 1.3
Amiga emulators and AmigaOS (with third-party software) can use these files as if they were virtual floppy disks. Unlimited virtual floppies could be created on modern Amigas, although WinUAE on a real PC can handle only four at a time, the maximum number of floppy drives that the Amiga hardware could have connected at any one time.
As the majority floppy-disks shipped by software-companies or as magazine-coverdisks still used this DOS type (which would boot on pre-2.x machines like the Amiga 500), this enabled users with existing OFS-formatted drives, that all older OFS-based disks could still be read afterwards, once they had installed FFS to the RDB of their start-disk.
The Amiga's floppy disk drive allowed 880 kilobytes on a single disk, comparable to the RAM of most Amigas (512 kilobytes to 1 megabyte). To increase capacity, Amiga used data compression. The disk drive had a slow transfer rate, such that using processor-based decompression could actually reduce loading times versus loading uncompressed data.
Mac 800 KB (requires a Mac drive) AMAX Mac emulator (a special floppy of only 200 KB to exchange data between Amiga and Macintosh could be formatted by the Amiga, and it could be read and written by floppy drives of both systems) Commodore 1541 (requires 5¼-inch drive slowed to 280 rpm) Commodore 1581 formatted 3 + 1 ⁄ 2-floppy for C64 and C128
The entire Workbench operating system consisted of three floppy disks: Kickstart, Workbench and ABasic by MetaComCo. The Amiga 1000 needed a Kickstart disk to be inserted into floppy drive to boot up. An image of a simple illustration of a hand on a white screen, holding a blue Kickstart floppy, invited the user to perform this operation.
CSG 5719 Gary, short for Gate Array, has been used in the Amiga 500, 2000(B) and CDTV. Gary provides glue logic for bus control and houses supporting functions for the floppy disk drive. It integrates many functions built discretely in the earlier Amiga 1000 in order to reduce costs.
