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.

IBM

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.
