I thought it (CM1) was a turd when I worked on it as a grad student. Looked cool though. I would go to conferences where people would proudly present their algorithm getting 1MFLOP. Parallel programming was hard then and it is hard now. SIMD made it even harder. CM2 was a little better since it was easier to get better performance, but we had some of the first machines and stability was not good. I think multiple sites where told they would have the first and TM shipped to them all in pieces simultaneously, so technically they all had the "first" machine. Smart guys. Still CM-2 was better than the ETA-10 we had. Cray-2 was great.
