@GregDavill it's a fun chip to play with!

We didn't.

@systems_glitch @CommodoreZ i reverse engineered the effect a few years back. https://t.co/cZC5sMYEKh

so my friend @compgeke has this computer with a really neat VGA BIOS screen: there's a rainbow shimmering effect on the logo! 🌈 but how does it work? (🧵...)

[Tube Time on 🟦☁ @TubeTimeUS]

ahh yes, the little known 3M Sandblaster Pro

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... 😉)

sometimes they look like this. it's perfectly natural, nothing to be ashamed of.

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. 👍

@DJSnM i don't think he ever completed it.

[Tube Time on 🟦☁ @TubeTimeUS]

@DJSnM my housemate in college bought a Kitfox that was about 80% completed, and stored it in our garage diagonally (it barely fit!)

after cleaning a couple of dirty contacts and freeing up the solidified grease on the subtract pawl here on the coin unit, the machine works again!

these old electromechanical pinball machines are tricky to work on. (yes i am aware of the Technology Connections video)

[Tube Time on 🟦☁ @TubeTimeUS]

it's a really crazy design, like there are differential signals going all over the place even with some length matching. gotta be at the picosecond level.

[Tube Time on 🟦☁ @TubeTimeUS]

here's a cool photo of a chip. this one is special because it's a real old-school photograph that i fed through my scanner.

[Tube Time on 🟦☁ @TubeTimeUS]

@Guino11_ enjoy!

[Tube Time on 🟦☁ @TubeTimeUS]

@blusnowkitty nope, still working on it.

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

@wrljet good finds! the large pentium pro CPUs are pretty neat looking as well.

[Tube Time on 🟦☁ @TubeTimeUS]

many of you are mourning the Z80 CPU (recently discontinued after a nearly 50 year run). all is not lost--i bet Rochester will take up the torch.

as according to the prophecy, Rochester will soon be the last remaining US semiconductor company.
