Ken Shirriff is a beast

It appears that BitCoin is working to infect every single computer on earth!

Is this an example of Intelligent Design or what?

Ducking.

The Xerox Alto is not that much faster at 1.5 hashes/sec

The 8 bit Arduino/AVR does about 150 hashes/sec at 16 MHz.

also by way of comparison a Pentium III Coppermine single core desktop processor from 20 years ago does around 250,000 hashes/sec and an Arm Cortex M0 microcontroller around 50k iirc.

Ken and his Computer Museum colleagues brought this AGC back from the dead, which is pretty cool. (I'm from then, so I care.)

I've been watching the Youtube channel , CuriousMarc. It's neat they have all theschematics and drawings. And even had Samtec mfg the connector pins for the AGC.

Also the Computer History Museum allowed them to Read the Rope memory modules they had on display.

I watched the series on YT a while back, the one where they were all camped out in a hotel room with components of the computer everywhere.

It reminded me of years ago when my only "lab" such as it was was in a corner of my mother's cottage and when sometimes a substitute housekeeper/aide for her would come on Tuesdays I just figured they'd either call the police or they'd seen much worse than that.

Well, now Samtec can advertise that they made connectors for the Apollo program, so everybody wins. ;)

Computer steampunk--gotta love it.

CHS used to be in downtown Boston before Mountain View "stole" it from us. Back when it seemed like 1 in 4 people in New England worked for DEC.

Have you seen the Cliff Stoll video and his old electronic calculator?

George H.

Yup.

Stoll is a bit of a beast too, though not on the same scale. I did enjoy "The Cuckoo's Egg" long ago.

Dumb.

Very primitive architecture even in its day.

It almost caused a crash landing:

And navigation control in an interpreter???

Apollo was not a scientific breakthrough, it was a gigantic waste of money. Nerd welfare, very unimpressive bunch.

It was the first and most expensive Reality-TV series :-)

u a nerd on welfare

Huh? The AGC was overloaded and automatically deleted a low priority task, so it could land safely!

Cheers

So what? In some real and philosophical respects, all computer hardware and software can be regarded as an interpreter.

Correct. But it was many many engineering breakthroughs.

Arguably and false. Apollo was very impressive, even for those that didn't (and in your case don't) understand the engineering.

Actually it was just the opposite. The astronaut wanted to use the radar al timeter to land, and the rtos kept kicking his command out because of overl oad. Then some ground control "brainiac" (sarcasm) figured out, in the midd le of damned landing, that he should use some kind of 'GO' command override instead. The ground control "brainiac" was later awarded a presidential me dal for his service, presumably for saving the U.S. from an ever more obvio us national embarrassment.

That's kind of a wackadoodle comment.

Your idea of "understanding" something is delusional.

You obviously didn't see this:

VERB? NOUN? Are you kidding me??? The interface was laughable!

That was particularly true for most computers in the 1960's-90's when most pre-RISC computers were microprogrammed.

Also most industrial control systems are programmed in interpretive systems like IEC-61131 or similar vendor specific systems.

Not to those that understand the philosophical concepts and practical engineering concepts.

I suggest you try to do better with the technology available at the time. You will fail.
