sehr gut erhaltenes Abschirmblech fuer den Amiga 1200
endlich wieder ein vollstaendiger Amiga 1200
Ich biete hier ein Originalabschirmblech fuer den Amiga 1200an. Die Abdeckung fuer das Mainboard ist das Teil am Amiga 1200, welches bei einer internen Erweiterung (Turbokarte, Flickerfixer/Scandoubler wie Indivision, Kickswitch, neues KickRom, etc.) zuerst demontiert wird. Soweit kein Problem, aber wenn man den 1200er dann nach ein paar Jahren mal wieder komplett haben will, ist dieses Blech genau das Teil, welches nahezu garantiert fehlt. Hier die Chance das passende Blech in einem guten Zustand zu ergattern.
For international bidders: I do ship worldwide. If you have any questions, feel free to ask.

The A1200 was considered the baby brother of the A4000 and was a very popular low-end machine of the early 1990's and is still popular among Amiga users today. It's probably the most common Amiga model still in regular use in vastly expanded forms. The A1200 came with a very poorly rated power supply (only 23w) so it was common practice to purchase third party power supplies or even use A500 power supplies (they are compatible) which have a higher wattage (65w?). Even a slightly expanded A1200 would often suffer from power problems.

A1200 by Commodore
A1200 by Amiga Technologies
In 1992 December Commodore released the A1200, its most popular Amiga model, based on the AGA chip set. From 1994 April to 1995 May no Amigas were produced when the new owner, Escom, created a division called Amiga Technologies and restarted the production of the A1200 and A4000T.
Processor 68020 @ 14-28 MHz
68030 @ 25-50 MHz
68040 @ 25-40 MHz
68060 @ 50-75 MHz
PowerPC 603e @ 160-240 MHz
All A1200s have a 68EC020 @ 14.28 MHz soldered to their motherboard. Upgrading the processor requires the use of a processor card which can be installed into the trapdoor slot. A 68881 or 68882 floating point unit can be installed on the motherboard, but no socket is provided.
Memory 2 MB Chip RAM
up to 256 MB Fast RAM on processor cards
up to 4 MB Fast RAM on PCMCIA cards
The A1200 has 2 MB 70 ns Chip RAM soldered to its motherboard which could not be expanded further.
Although the A1200 is an entirely 32 bit machine, the 68EC020 processor has only 24 bit address space (16 MB) besides its 32 bit data path. This allows 8 MB for Fast RAM expansion which can be added either via a PCMCIA card or via the trapdoor expansion slot. Further expansion of the Fast RAM requires the use of a processor card.

A1200s manufactured by Commodore shipped with Kickstart 3.0 ROM which can be replaced with a 3.1 one. All the Escom ones have Kickstart 3.1.
Expansion slots
1× processor card slot
1× PCMCIA slot
1× "clock" port
The 150 pin trapdoor expansion slot is designed for processor cards, memory expansions and DMA SCSI controllers.
The 68 pin PCMCIA slot accepts industry standard peripherals if the suitable driver software is present.
The 22 pin clock header was intended to be used for a battery backed up clock and an 1 MB Chip RAM expansion for the never released 1 MB A1200s. Nowadays there exist several expansions like sound cards or I/O controllers.
The A1200 has a vast array of upgrade options, including processor cards, SCSI controllers and many other types of expansion.
Interfaces
1× serial DB25 male, RS232
1× parallel DB25 female, Centronics
1× video DB23 male, analog RGB
1× composite video, RCA jack
1× RF modulated video, RCA jack
2× mouse/game DB9 male
2× stereo audio RCA jack
1× external floppy DB23 female
1× internal floppy 34 pin header
1× internal AT IDE 44 pin header
The built in IDE controller supports two IDE devices connected simultaneously, although there is only one internal drive bay for a 2.5" hard disk drive. Unlike the A4000 the A1200 has a non-buffered IDE port. Only mode PIO 0 is supported.
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 A1200's compact case.
