Datasheet

The first ever Amiga released in 1985. Features include
preemptive multitasking, coloured graphical user interface 
and stereo sound.

Processor
68000 @ 7-14 MHz 
68020 @ 7-20 MHz 
68030 @ 14-50 MHz

The computer has a socketed 68000 @ 7.09 MHz (PAL) 
or 7.16 MHz (NTSC). To upgrade the processor requires 
the use of a processor board. Quite a number of the
boards designed for the A500 work on the A1000, 
whether connected to the side expansion port or 
to the 68000 socket.

Memory
256 kB Kickstart RAM (Writable Control Store) 
up to 1 MB Chip RAM 
up to 32 MB Fast RAM on processor cards 
up to 8 MB Fast RAM on side expansion cards

The A1000 comes with 256 kB Chip RAM soldered on to its 
motherboard. This can be expanded to 512 kB with a memory 
expansion card. Chip RAM can be expanded to 1 MB with 
third party expansions like the Rejuvenator. 

Fast RAM can be added either via the side expansion 
connector or via processor boards.

Custom chips
Agnus - OCS display controller 
Denise - OCS graphics coprocessor 
Paula - audio and I/O controller 
Gary - system address decoder

The A1000 supports either PAL or NTSC screen modes, though
not both. The Low resolution screen modes offer up to 32 
colours from a palette of 4096, and 4096 in HAM mode. 
High resolution screen modes offer 16 colours from 4096. 
4 channel stereo 8 bit audio output with frequencies up 
to 28 kHz.

Expansion slots
1× side expansion slot

The Amiga 1000 has the same 86 pin connector as the one 
later utilized for the A500. Whilst many A500 expansion 
boards work with the Amiga 1000 it must be remebered that
the units are a different way round with its port on the front.

Interfaces
1× serial DB25 female, RS232 
1× parallel DB25 male, Centronics 
1× video DB23 male, analog RGB 
1× composite, RCA jack 
2× mouse/game DB9 male 
2× stereo audio RCA jacks 
1× keyboard RJ12 
1× external floppy DB23 female 
1× internal floppy 34 pin header

The floppy drive controller supports up to four devices. 
One can be attached to the internal floppy header and 
three connected to the external floppy port. Both double 
and high density disk drives are supported. An 880 kB 
double density floppy disk drive is built into the A1000.
