In the @BlackHatEvents Book Store you can find "Open Circuits" - a wonderful @nostarch book about the internals of various things by @oskay (buts psst: they only brought 15 copies, 6 left, two on hold... ๐)

I need a breadboard that fits all the newer microcontroller dev boards that are gigantic like the ESP32 Dev Kit boards or FPGA boards. I also just want more slots sometimes.
And every other column should be gray. ๐

I received a mysterious aerospace computer from the early 1970s, probably for navigation. It is crammed full of flat-pack integrated circuits surrounding a core memory module. Let's take a look inside... 1/17
ALT A compact aerospace computer with a numeric keypad and digit displays on the front. A circuit board with multiple flat-pack ICs is visible.

fun fact! the numbers in coin cell part numbers are dimensions. a CR2025 is 20mm diameter and 2.5mm thick!
ALT a digital caliper measuring the thickness of a coin cell (2.5mm) but the caliper is made of metal, obviously shorting out the coin cell.

X-Ray of an NCR 6500/1P with particularly good contrast on the bond wires.

This looks like a pretty simple computer program right? Maybe a while loop, a delay and writing some data to an output port?

Did you see my chat with @TubeTimeUS about the MOnSter 6502?
Lots of interesting overlap between this incredible #PCB design and #ASIC tooling!

Now vintage PCs can have a native connection to modern HDMI monitors without any additional adapter.
Thanks to giants like @TubeTimeUS whose Graphics Gremlin work I have built upon.

All Electronics in Los Angeles is shutting the doors tomorrow.
Get down there if you are in LA

Fighter jets in the 1950s used the electromechanical Bendix air data computer to determine Mach number etc. I hooked up a gauge to the pressure transducer section so you can see the gears spin and the dial turn.

Eric @TubeTimeUS and Windell (EMS) will be speaking at VCF West tomorrow (Friday, August 4), in an interview about the book Open Circuits ( opencircuitsbook.com ).
VCF West is at the Computer History Museum in Mountain View CA, more info at: vcfed.org/events/vintage-comโฆ

#ThrowbackThursday to 1977, when the CERN Bulletin announced that CERN's computers were then able to handle words, as well as numbers. ๐ง
These pictures feature the display console of a CDC 3100 computer at CERN. From that year, these computers had their own special text-handling system, allowing all kinds of users โ not just computer specialists โ to produce reports, letters, and more.
The latter pictures show the display console being used with a โlight-penโ to examine particle track configurations, such as those that could be produced in a new bubble chamber.
