The software to land on the Moon was woven by hand into core rope memory: wire through a core for a 1 bit, around a core for a 0 bit. Apollo Guidance Computer's ropes held 36K of 15-bit words and used the first amplifier integrated circuits. #Apollo50 righto.com/2019/07/softwa…

Restoring an IBM Interpreter (1957) at @ComputerHistory. It read a punch card and used typebars to print the contents on the top of the card. It was "programmed" with a plugboard. We have it partially working, printing about half the columns. Video shows brushes reading the cards

Someone uploaded a WIP3OUT Press CD from the time of the release of the game, and it's a great insight into a variety of graphics and culture around early Playstation history. (1999)

Back when there were 12 pence in a shilling and 20 shilings in a pound, the IBM 1401 computer had optional hardware (i.e. transistors) to do arithmetic on pounds/shillings/pence. Of course, there were two incompatible data standards—BSI and IBM—so this knob selected the format.

In the 1960s, mainframe used core memory for storage; 128 kilobytes filled a large cabinet and weighed 610 pounds. Core memory consisted of tiny ferrite cores on a wire grid. By 1970, IBM produced 20 billion cores a year. I examine an IBM S/360 core array: righto.com/2019/04/a-look…

The revolutionary IBM System/360 computers were announced 55 years ago today. These mainframes ruled the computing industry for years. Their iconic consoles, covered with lights and switches, showed internal state. I explain these consoles in my article: righto.com/2019/04/iconic…

Just noticed: Intel's manuals had some amazing and vibrant covers back in the day. They scream "80's", don't they?

A diagram of different transistor die layouts from Fairchild, 1966. (Thanks to William C. for sending me this.)

Speaking of SNK, there has got to be a better master copy or maybe even b-roll of this mid-1990's SNK corporate video somewhere. Great NEO-GEO development department and factory footage here.

I've released an archive of the 13 low-level challenges I developed for CTFs organized with @DragonSectorCTF in 2014-2018, mostly Windows/Linux pwning. This includes task binaries, write-ups and exploits. I hope it'll entertain some more hackers 💻 github.com/j00ru/ctf-tasks

@isonno @unicode Here are some die photos of the MIPS R10K: first the original die, then the die with much of the metal removed, and then the die with all the metal removed to expose just the silicon.
