Getting Apollo 13 back. Doing calculations and burns on the fly. Steering the LEM as doing the burns. I mean it is really a miracle they got back.

That reminds me of a scene in the movie "Apollo 13" where everyone breaks out slide rules to run calculations. It's hard to remember just how primitive the electronics back then were compared to today.

One of my all-time favorite movies.

Well they supposedly did all the calculations on a primitive IBM mainframe and that would take weeks to run. After the accident on 13, they were doing stuff on the fly. I am still amazed they made it back.

MY HP 12C calculator had more computing capabilities than the computers on board those flights. Amazing

Electronics? I see no electronics here. Only Keuffel & Esser.

Of course, on board Apollo, they did have electronics. 4mhz, 72k RAM.

“It’s hard to remember just how primitive the electronics back then were compared to today. “

Does anyone have any specs of the onboard computer in first apollo command ship?

I’ve often heard a rumor that the old XT clones with a 20 meg HD were larger storage and more powerful.
