Boing boing!

Commodore Amiga 1000Publié le 07/11/11 à 14:24
Chronologiquement j'ai eu un A500, un A2000, un A1000 & un A4030.
J'ai jouté les A600 & A1200 à mon "pedigree" vu le nombre d'Amigas que j'ai fait adopté à l'époque du lycée!
A Gisors, on pouvait chercher les 520St: il n'y en avait pas/plus!
Les rares possesseurs avaient migré vers l'Amiga.

Mon A1000 dispose de 512Mo de Ram, d'un kickstart sur floppy (et non en rom)... Et bien sur d'un capot ABS signé par les ingés & plus!

J'ai donc un A1000, avec le capot "signé" par les ingénieurs... et plus!

Fiche technique

  • Fabricant : Commodore
  • Modèle : Amiga 1000
  • Catégorie : Autres Micro-ordinateurs
  • Fiche créée le : 01/04/2005
 

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.

Processor

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

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 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
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

16 / 4096

The A1000 supports either PAL or NTSC screen modes, not both. 
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

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.

Look up the A1000 expansions from the database.

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 attached to the internal floppy header and three connected to the external floppy port. Both double and high density disk drives are supported. 
A 880 kB double density floppy disk drive is built into the A1000.

Motherboard revisions

Agnus 8361
Denise 8362 R5 or R6 - early models had R5 which did not support EHB screen modes
WCS (Writable Control Store) is placed on a daughterboard
PAL (Photo)
Agnus 8367
Denise 8362 R6
WCS is part of the motherboard, there is no daughterboard
(early PAL A1000s were based on the NTSC motherboard)
