Apollo Guidance Computer

I talked with Frank O'Brian, the caretaker of the Apollo Guidance Computer exhibit at InfoAge in NJ about this subject. He provided this tidbit of info that I thought I could share here. While looking at the original code listings for this computer, (at the exhibit) it's quite amazing how they accomplished all this math within such a constrained environment given the technology of it's day. I feel this would make some people scratch their heads :) What type of arithmetic operations were used to perform all the calculations on the Apollo Guidance Computer ? a) Floating Point arithmetic operations b) Fixed Point Arithmetic operations c) Integer Arithmetic operations d) Slide Rule Arithmetic operations e) all of the above =Dan [ Pittsburgh 250th --- http://www2.applegate.org/~ragooman/ ]
