Hell distinctly remember encountering the epitome of technology, electronic technology anyway, the IBM 360
Rolling out yards of pin-feed computer paper on the floor to write flow charts, prior to punching stacks of cards & waiting all nite to see if the program ran
But it was great, was able to solve iterative problems without inventing some kind of clever approximation to get the 1st guess – Could invert a 3X3 matrix without going thru a ream of paper -
Wrote the 1st FEA program, that I am aware of but thought a finite difference approach would be more efficient
Something that got lost, that sometimes I still miss, is analog computing – Could watch a simulation happening in real time, speed it up, slow it down, run it backwards – MTU had a hybrid that was really fun, could use the digital computer to input forcing functions to the analog & simulate way cool things like shocking a cardio vascular system
For a few months made my bread designing HVAC systems for computers that I was not allowed to be in the same room with
BUT
I kept my slide rule against the possibility some moron drops the bombs & I can still use it.
