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.

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.
We need more info about this computer ! If you designed, used, or have more info about this system,
please send us pictures or anything you might find useful.
Please consider donating your old computer / videogame system to Old-Computers.com or one of our partners from anywhere in the world (Europe, America, Asia, etc.).
I had an ABC, bought in 1990 or 1991. It had a 16MHz 286, 1MB RAM, and an onboard Paradise VGA - 640x480 in 256 colours, 800x600 in 16 colours, but rather slow since it didn''t have any acceleration features. There was a 3.5" floppy drive and a 60MB ST506 harddisk.
Eventually we got a 287 and it turned out the SIP sockets would accept 30pin SIMMs by just placing a SIMM socket into the SIP...

Atari PC late ''87 - EGA graphics and an amber monitor 5.25" 360k floppy Gem desktop and MSDOS 3.something. yeah, my first computer. Researched the chips needed for expansion to 640 k, tracked them down through a local electronic supplier and popped the hood. Got those in and looked at the pc speaker pins an ran those to a "mic" plug and into my boom box aux. Sure, it was pc speaker sound, but it had bass, and spread.
Found a dos util for RAMDisks and tweaked the performance by creating a RAMDisk, copying command.com to the RAMDisk and setting Comspec$c:$command.com
That batchfile grew, assimilated improvements and cli parameters to facilitate copying from one floppy to another through creating a RAMDisk to act as a buffer between prompted, batch language scripted disc swaps. Oh, and a assembly language snippet from an early PC mag that used DOS Debug to overwrite the partition table of the primary hdd with null. Evolved into a Swiss army kind of thing. Even used it at my first real pc job, building them for a lical whitebox manufacturer in 92, then running the service department
Thanks for the memories

Fernando Bautista, su "PC" (para no confundirla con la ST) de Atari puede valer diversas cantidades dependiendo del modelo (PC1, PC2, PC3, PC4 o PC5, sumados a una laptop). En Ebay encontré un modelo de "PC" vendiéndose a 999 dólares, lo cual serían 18.519,01 pesos mexicanos. El valor original de la "PC1" era de 499 dólares (9.250,23 pesos mexicanos), que ajustado para la inflación moderna serían 1048 dólares (19.427,35 pesos mexicanos)
Otra oferta en Ebay, vendida hace ya 4 años, era de la computadora, el disco duro y el monitor, y valía 152,50 dólares (2.826,98 pesos mexicanos)
Espero que haya podido ayudar! :D
