This is real hard work, Chris. U built every unit, the multiplier, the adder and the rest of alu stuff. These units are the most time consuming and difficult to debug too. Impressive. Whats ur next target.
Just visited the first Cray-1 (so they tell me) at NCAR in Boulder, CO. I threw a few photos up on a web page if anyone is interested at http://homepage.mac.com/cheilman/NCAR_Cray_1/. I grew up in Eau Claire just south of Chippewa Falls, WI where Cray Research was founded (and almost ended up working there years ago). I recall studying the architecture back in grad school. Thanks for the memories!
Great job, Chris, really impressive! So, from your description of the hardware architecture of the Cray-1 it seems modern CPUs haven't actually moved much in terms of architecture compared to their grand-dad :D
