You can find plenty of tech demos out there, but how many can run on an IBM Model 5150 or be packaged into a 180KB file? Continue reading to see our recap of these incredible demonstrations.


First released on August 12th, 1981, the IBM Model 5150 was the world’s first PC. It came with a host of business and productivity tools, but only CGA graphics. Fortunately, a modder hacked one of these 4.77MHz wonders (640K RAM + 10MB HDD) to run a 30fps, full motion tech demo in color. Video courtesy of OldSkool.

180KB File

Put simply, this 3D tech demo could quite possibly be the best we’ve ever seen — considering its 180KB file size. To run this demo smoothly, you’ll need a Core 2 Duo or Athlon X2 processor, 1GB of RAM, and a GeForce 7600 / ATI Radeon X1600 or better graphics card. Download page.
