The Amiga 600, also known as the '''A600''' (codenamed "June Bug" after a B-52's song), was a Home Computer introduced at the CeBIT show in March 1992 . The A600 was the final model of the original A500 -esque line based around the Motorola 68000 processor and the OCS chipset. It was essentially a redesign of the A500 Plus . It was intended by manufacturer Commodore International to revitalise sales of the A500 line before the introduction of the 32-bit Amiga 1200 . A notable aspect of the A600 was its small size. Lacking a Numeric Keypad , the A600 was 14" long by 9.5" deep by 3" high and weighed approximately 6 pounds. It came with AmigaOS 2.0 and was generally considered more user-friendly than OS 1.3. Like the A500 before it, the A600 was aimed at the lower "consumer" end of the market, with the higher end being dominated by the Amiga 3000 . According to (comp.sys.mac.hardware.misc).

This is supported by the fact that the A600 was originally to have been numbered the A300, positioned as a budget version of the A500+. In the event, the cost led the machine to be marketed as a replacement for the A500+, requiring a change of number. Early models feature motherboards with the A300 designation. The Managing Director of Commodore UK, David Pleasance , described the A600 as a "complete and utter screw-up". It was unexpandable, did not improve on the A500's CPU, was more expensive than the A500, and lacked a numeric keypad, meaning that games such as '' F-19 Stealth Fighter '', '' Railroad Tycoon '' and productivity software could not be used without a numerical pad emulator. The A600 was the first Amiga ever manufactured in the UK. The factory was in Irvine, Scotland . The first ever production A600 — serial number "1" — resided in the Commodore UK Managing Director's office. It had a failure rate under warranty of 0.78%, much better than the A500's rate of 8.25%. PROCESSOR AND RAM The A600 used the Motorola 68000 processor, running at 7.09 MHz ( PAL ) or 7.14 MHz ( NTSC ). Standard RAM was 1 MB , though many people upgraded to the maximum of 2 MB "chip" RAM using the trapdoor RAM expansion. An additional 4 MiB of "fast" RAM could be added if the PC Card slot was employed. Even more "fast" RAM could be added with a processor upgrade. The original design did not intend for processor upgrades as the 68000 was soldered to its motherboard. Despite this, unofficial processor upgrades included the Motorola 68010 , 68020 (at up to 25 MHz), and 68030 (at up to 50 MHz) processors. (The processor was upgraded not by unseating the 68000 and dropping in another chip, but rather by pushing an accelerator board connector on top of the 68000 CPU, which then commandeered the system bus.) Additionally, up to 32 MB of "fast" RAM could be added with some processor upgrades. GRAPHICS AND SOUND The Fat Agnus display chip drove screen modes varying from 320×200 pixels to 1280×512 pixels. Generally only 32 colours were available, but there was an extra-half-bright mode that allowed each of the 32 colours in the palette to be dimmed to half its normal brightness. A memory-intensive 4096 colour " HAM " mode could be used at lower resolutions. At its highest resolutions, only 4 colours could be displayed at once. Sound was 4 channel, with two channels for the left speaker and two for the right. Resolution was 8 bit. Sound was unchanged from the original Amiga designs. PERIPHERALS AND EXPANSION One 3.5" internal floppy drive was standard and a second could be added externally. Two DB9M ports for Joystick s, Mice , and Lightpen s were included, plus a standard 25-pin RS-232 serial port and 25-pin Centronics Parallel Port . Other expansion connectors included the PCMCIA Type II slot and the internal 44-pin ATA interface (for the 20 or 40 MB 2.5" disks — both expensive for the time) wich used the 'Gayle' chip. 1 070726 amigahardware.mariomisic.de 2 070726 amigahardware.mariomisic.de 3 070726 lxr.free-electrons.com, Soucecode of the Amiga 600 Gayle chip The model with the integral ATA drives was sold — for almost double the price of a standard A600 — as the "A600HD", with a white rather than cream outer casing, and was marketed as a more "scholarly" version of a home computer hitherto best known for its extensive range of games. Some games, however, were used to using every last system resource available to the standard Amiga so, for example, to run some games such as ''Civilization'' from the Hard disk a memory expansion to take the available RAM higher than the standard 1 MiB was required. Other add-ons included MIDI interfaces and sound Samplers . OPERATING SYSTEM The Amiga 600 was shipped with AmigaOS 2.0, consisting of Workbench 2.0 and a Kickstart ROM which was either version 37.299, 37.300 or 37.350 (Commodore's internal version numbers). Confusingly, all three ROMs were officially designated as version "2.05". Early revisions of the Amiga 600 were shipped with Kickstart version 37.299, which, to the surprise of some, neither had support for the internal ATA controller, nor for the PCMCIA interface. Although it was possible to load the necessary drivers from a floppy disk, it wasn't possible to boot directly from ATA or PCMCIA devices. Only later models of the Amiga 600 and especially the Amiga 600HD were equipped with Kickstart 37.300 or 37.350, which both were able to utilize those devices at boot time. Due to bugs in Kickstart 37.300, the maximum supported size of a hard drive was limited to 40 MB. Everything above this size was a game of chance. In contrast, version 37.350 was capable of supporting hard drives up to 4 GB. Later it was possible to buy an updated Workbench 2.1. It featured a localization of the operating system in several languages and had a "CrossDOS" driver which provided read/write support for FAT (MS-DOS) formatted media like floppy disks or hard drives. It was a pure software update. Kickstart ROMs designated as 2.1 never existed. Workbench 2.1 ran on all Kickstart ROMs of the 2.0x family. BUNDLED SOFTWARE Originally the computer came bundled with '' Lemmings '', '' Captain Planet & The Planeteers '', '' Shadow Of The Beast III '', and '' Bart Simpson Vs. The Space Mutants '', all of which had been bundled with the A500+, and the sophisticated-for-the-time Electronic Arts graphics package '' Deluxe Paint 3''. Shortly afterwards the Wild Weird and Wicked bundle was launched, featuring '' Formula One Grand Prix '', '' Pushover '' and '' Putty ''. Many retailers added a bundle of more up-to-date games, including '' Zool '' and '' Pinball Dreams ''. TECHNICAL SPECIFICATIONS
