The Amiga A2500 was introduced in November 1988, as a machine for power-users. It was essentially an B2000 that initially
used the Motorola 68020 processor but this was soon upgraded to the 68030 processor, and came with the upgraded A2091 hard
disk controller card, that eliminated booting problems. With 512Kb of Chip RAM and 512K of Fast RAM, these machines were
often supplied with the 8MB memory card, and when upgraded to the ECS chipset, the 512K of fast RAM was converted to Chip
RAM. The flicker experienced in hi-res mode was overcome using a frequency doubler (flicker fixer) but this required a more
expensive multi-sync monitor.
Many of the machines were made to order and often included video genlocks, soundcards and other add-ons especially for
professional users. At the time they were most impressive.
