My research work at the time was density matrix calculations on systems of two protons. This produced a system of 16 simultaneous equations to be solved once for each required point on the spectrum bandshape. The poor old ICL 1905E took around 500 seconds to calculate a 1000 point spectrum and this made iterative fitting of experimental spectra with a similar time penalty for each small parameter change "prohibitively expensive" in the words of Prof. Rex Richards who refereed our first publication in this area. Done in a twinkling on todays home computers! Try it on your Windows PC! which will demonstrate how fast your current system is compared to the 1905E.
