A working scale model Cray-1A

I remember seeing this about 9 months ago: http://news.ycombinator.com/item?id=1645291

I think at that point, it was still only 33MHz (he now has it running up to 50MHz), it sounds like he's also got a slightly more mature software toolchain now. Oh, and he's added a link to a DOS-compatible Cray simulator, for anyone who wants to play along at home without getting involved with the hardware side.
