Due to the new Kickstart v2.04, quite a few popular games (such as Treasure Island Dizzy, Lotus Esprit Turbo Challenge, and SWIV) failed to work on the Amiga 500+, and some people took them back to dealers demanding an original Kickstart 1.3 Amiga 500. This problem was largely solved by third parties who produced Kickstart ROM switching boards ...
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
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.
It makes hard drive, 4x floppy disk and write support possible. [10] The FPGA core is the same for the new ARM and PIC firmware but only the ARM has enough resources to support four drives. The PIC only supports two. The upgrade also allows an increase of the CPU speed from 7.09 to 49.63 MHz with a 4 KB zero wait state CPU cache.
Rob Northen Copylock (also known simply as Copylock) is a copy-protection system designed to prevent disk duplication with standard floppy disk drives on the Amiga, Atari ST, and IBM PC compatibles. It was created by British programmer Rob Northen after founding his own company Copylock Software. It was used mainly to prevent games from being ...
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.
