[Chris Fenton] needs your help. After constructing a 1/10th scale, cycle accurate Cray-1 supercomputer and finding a disk with Cray software on it, he's ready to start loading the OS. There's a small problem, though: no one knows how to boot the thing. [Chris] posted a disk image for a Cray-1/X-MP with the help of the people at archive.org. Now he needs your help - if you think you can … [Read more...]
Recovering data for a homemade Cray
September 8, 2011 By 41 Comments
In our hubris, we pat ourselves on the back when we're able to pull data off our old SCSI drives. [Chris Fenton]'s attempt to get an OS for a homebrew Cray-1 puts us rightfully to shame. Last year we saw [Chris]' fully functional 1/10th scale Cray-1 supercomputer built around FPGA. While the reproduction was nearly cycle-accurate, [Chris] hasn't had an opportunity to test out his system … [Read more...]

[Chris Fenton] spent a year and a half constructing a 1/10th scale Cray-1 reproduction. The famous supercomputer was meticulously modelled in a field programmable gate array for a "nearly cycle-accurate" reproduction. [Chris'] hardware of choice for the project is a Xilinx Spartan-3E 1600 development board, using 75-80% of the available resources. The finished product runs at 33 MHz and is … [Read more...]
