ARM's 35th birthday

And the hardware wet dream :D

Wow – a real beast!

Prof. Furber: “They were put straight into the development system which was fired up with a tweak or two”

One of the tweaks being the addition of a power line into the CPU

I thought the story was that it worked without the power line being connected, since it required so little power to do its thing?

I’ve read that it was after they had run some tests with it that they discovered that the positive power lead hadn’t been connected. Apparently it had drawn all the current it needed from the test equipment leads.

I’m fairly sure that I read this in one of the regular bulletins that Computer Concepts used to issue.

I heard that they couldn’t get the damn thing to reset itself by power-cycling the machine (what, no reset button?) because the latent power generated by the PSU’s cooling fan spinning down was enough to keep the processor running. [I think the Arthur vs ARX transcript mentions this?]

Whatever is truth and embellished mythology, one thing for certain is that there’s a reason all our itty bitty shiny runs on ARM and not Intel.

That was on the A500, Rick, case cooling fan. It certainly had enough back EMF to keep the DRAM contents valid for a few seconds.
