In 1985 July the first Amiga, the A1000 appeared. It costed half as much as the 8088 XT of that time, featured an operating system with preemptive multitasking, coloured graphical user interface and stereo sound.
68000 @ 7-14 MHz
The A1000 has a socketed 68000 @ 7.09 MHz (PAL) or 7.16 MHz (NTSC). Upgrading the processor requires the use of a processor board. Many boards designed for the A500 works perfectly in the A1000, either connected to the side expansion port or to the 68000 socket.
256 kB Kickstart RAM (Writable Control Store)
The A1000 has 256 kB Chip RAM soldered to its motherboard which can be expanded to 512 kB with a memory expansion card. Chip RAM can be expanded to 1 MB with third party expansions such as the Rejuvenator.
Agnus - OCS display controller
The A1000 supports either PAL or NTSC screen modes, not both.
1× side expansion slot
It is the same 86 pin connector as the one later utilized on the A500. Many A500 expansion boards work flawlessly however the units are the wrong way round with its port on the front.
