Atari's first PC, it included CGA, Hercules, and EGA graphics all
on one universal port (a first for its time). 512KB of RAM was
included as well as the 5.25" Disk Drive. You can even connect
external floppies that worked on the Atari ST (the SF354 and
The case was the same as the MEGA ST series and this
computer is very rare, having not sold as well as Atari would have
liked. This model ran the Intel 8088 microprocessor at 8 MHz and
included the GEM Operating Environment (a competitor to
Windows, the Mac, and Amiga).
KevinT on Friday, October 26, 2012 This was my first PC and I actually developed on it with Borland Turbo C 1.0. I'd upgraded it to 640K, installed a NEC V20 processor for better performance, and one of those real time clocks that stacked under the ROM BIOS, setting the system clock at bootup thanks to a utility in the autoexec.bat.
(In those days the average PC didn't have a real-time clock, as most tasks you'd perform with them didn't require the accurate date or time. Conditional compilation with Turbo C required the proper timestamps on the files however, otherwise you'd have to wait for your whole project to recompile every time you made a change. Slow enough with a hard drive, eternity from floppies!)
To get Turbo C to work painlessly without a hard-drive or endless disk swapping, my boot floppy created a ramdisk the exact size to contain C0S.obj and cs.lib for linking, then I'd switch to the floppy containing Turbo C and ran a batch to copy the necessary files to the ramdisk and start the environment, then finally I could switch to the work floppy containing the source and the compiled/linked output. After that, no further swaps were necessary. (Ah, them's were the days...)
Eventually I upgraded to a 286 machine and swapped my PC-1 for an ST with a guy in Stratford who used it to run the second line on his BBS. Given the PC-1's lack of a harddrive or any expansion slot you wouldn't think that makes any sense, but it's bookshelf friendly size and a LANtastic parallel port adapter actually made it the perfect box for the job. I wonder where that machine is now???
