Where great old Macs live again!

That's not retro. Now *THIS* *IS* RETRO...

I saw this and thought of RetroMacCast...

This is a quick blurb about the computer used on the Lunar Excursion Module (LEM) betwen 1969 and 1972 on http://dvorak.org/blog

A Brief Look At The Computer That Helped With The Lunar Landing

From the posting:

It’s cycle time was 1 Mhz, 11 instructions. It had 1K of 16 bit words of erasable (RAM) core memory and 12K of read-only memory (ROM). The ROM held the “Colossus 249″ flight control software. There were no disks or tapes in the flight system.

That should be proof enough that there's no way we were able to go to the moon with the technology back then. Therefore, the whole stunt was staged on a Hollywood set.

I certainly would have had issues trusting my life to it. Even though I was only 6...

1 mhz 1k of RAM.... wow! Most of the flying must have been done manually.... if the computer was trusted, Apollo 11 would have certainly crashed into the boulder field during the last seconds of its lunar landing.

I liked the associated link describing that the module had to reboot several times during the landing sequence due to memory overloads. This and the fact that it re-loaded the most recent data.

Also liked the fact that the computer module was exterior to the spacecraft meaning no physical intervention was available.
