Just my weak and dim memory. As an analytical chemist I lived with the 360/370/Amdahl, etc. scientific subroutine package. I used it for fitting analytical curves, both atomic absorbtion and antibiotic agar diffusion analysis. Finally we got both the pdp-11 dedicated to the AA and pc's on the desktop for handling analytical data. Long time ago. Next week I will have been retired for 19 years. I've loved every one of them!
