A homebrew computer hacker named Chris Fenton has built a working 1/10-scale Cray-1A computer replica which is binary-compatible and cycle-accurate to the original.

The project was hard because Chris not only wanted the replica to perform like the original, he wanted it to look like the original. He was also working on a budget and didn’t have many thousands of dollars to throw around. If you just want to run Cray code, there’s a DOS-based Cray emulator you can download.

The irony here is that the Cray was once promoted as “the machine that will change the world” while microcomputers like the Altair 8800 and Apple I were dismissed as toys. Yet, it was the microcomputer that changed the world, and now, the Cray computer has been (quite literally!) reduced to a toy.

Today, the “experts” in Congress tell was that the Space Launch System is the rocket that will save space exploration; suborbital rockets like SpaceShip Two, Lynx, and XAero are toys.

Those who fail to learn the lessons of history can still run for Congress.
