I only wish that my memories of System 360 machines were pleasant! For scientific work it was powerful but obscure and clumsy. Error codes were incomprehensible except for the closing phrase which always said ' probable user error'. IBM JCL made vi editor commands look like nursery rhymes and the floating point exponent range was so limited that you were forever chasing underflow / overflow errors.. It did however have a mind boggling 256kB of memory and ran at 1MIP (360/195).
