A > ATARI  > PC   


Just after the Atari ST series, Atari decided to launch a series of PC compatible systems. The PC-1 was the first model. It used the shell of the Atari Mega ST4 and its mouse. It held 512 KB of RAM, an optional 20 or 23 MB HDD, but didn't have ISA extension slot, to use a PC card, an expansion box was necessary.
However, the PC-1 had Parallel, serial and mouse ports built-in as well as an universal video interface allowing either colour CGA and EGA or Hercules monochrome monitors to be connected to the same video port.

The range of Atari PC compatible systems was also comprised of:
• The PC3, a 8088 8Mhz based system with 640 KB ram, CGA graphics and 20MB hard drive,
• The PC4, a 80286 16Mhz based system with a 60MB hard drive in which - optionally- a 3.5 1.44 Mb drive could be fitted (the front needed to be cut out and the metal casing sawed by the user). It also featured VGA graphics,
• The ABC, a 80386sx 16Mhz model with a 40MB hard disk and vga graphics. This one came with a 3.5 floppy built in,
• The PC5, a 20MHz 80386 PC featuring 60 MB hard disk and SVGA graphics with same 3.5 floppy disk option as with the PC4,
• the N386 laptop.


Matt Lloyd adds:
I bought one of these when I attended college in 1988. The Ram was expandable to 640K. However the selling point was it had an ST compatible floppy/HD connector which meant that you could add ST floppy and hard drive which were alledgedly cheaper than the PC equivalent. It also came with the GEM operating sytem in an attempt to provide an ST like interface for the PC.
