This Central Air Data Computer (CADC) was introduced in 1955. It computed airspeed, altitude, etc for fighter planes. But instead of a processor, it was an analog computer that used tiny gears for its computations. Let's look at how one of its modules works.🧵
@kenshirriff looking forward to reading/seeing more about it once you have a chance to power it up! i enjoy seeing this sort of thing that fits neatly at the intersection of #avgeek, #vintagecomputing, and a whole ton of other topics that escape me atm.
If you enjoy browsing vintage computer magazines you might enjoy using Lobo Reader, a web based app for mobile that streamlines reading from the Internet Archive Magazine Rack. I find it works better than the native interface. Simply add to your home screen and enjoy!
I pulled an AGP GPU (GeForce6200) from a mobo to examine it closer...and now I'm getting a long beep from the machine with it reinstalled. I tried a second AGP card and get the same error.
The mobo (L4S5MG3/GX+) allows for onboard video, but I'm getting the same long beep (~10 seconds) with no card installed.
I'm in the process of diaging...but I'm not even sure what I did to cause the issue. 😂
So...except for maybe its AGP capabilities, is it a good idea to actually hang onto a P4 machine? What capabilities would you find desirable of machines from that time frame? Is there anything in the gaming realm that benefits from an AGP/P4 setup that can't be handled by later architectures?
Maybe we are a bit peculiar: My son on the first night of a two week school holiday, repairing a 1985 Makita drill, talking to a friend on Discord who is putting a terabyte HDD in a 2008 iMac while I'm drinking a beer and figuring out if which old X86 laptop/desktop I can turn into an Pimiga 3.0 machine because apparently you can and RP4 turned expensive.
Recently @blakespot posted Jack Haeger's "Four-Byte Burger” #Amiga#PixelArt. Today YouTuber Ahoy posted about his process to recreate it from scratch using photographs, even posting a PNG of the final work (scaled for modern displays).
I was able to work backwards to create an Amiga IFF version so I too could display it on an Amiga and CRT.
Four Byte Burger displayed on an #Amiga 1000 and a rare #Commodore 1070 monitor, the original monitor paired with the Amiga 1000, rotated 90 degrees for portrait display. The image is stunning in person on the CRT!
*Edit: Replaced image with correctly rotated image. Ahoy's original version needed to be rotated the other way for this orientation.
The Commodore 1070 is likely the same monitor Jack Haeger had access to when he created Four Byte Burger using an early version of Graphicraft. Here's Andy Warhol using the same monitor rotated in portrait orientation.
Starting six years ago this month: "City Planning," a series of pen plots that imagines fictional city grids. This algorithm evolved over the years to include circles, waterways, and devoid areas and I continue to build upon it.
A #generative#PenPlot drawing of parallel lines that form rectangles in white ink on black paper. In certain quadrants, the angle changes. It looks like a fictional city street map.

Detail (upper left) from a generative pen plot of cyan, yellow, and magenta lines whose end points touch but not intersect, with certain bounded areas hatched. The colors layer on top of one another to create vibrant colors. A large circle dominates the center-right of the image which interrupts the otherwise straight lines. #PenPlotter

Well masthead.social died so it's new account time.
Hi! I'm James (@jamesfcarter) and I run Starring the Computer, a website that chronicles computers that appear in movies and on television. Ok, so it's a bit niche, but that's what the internet is for, right?
Flying out of PHL, I always check to make sure that they haven’t replaced the old Mac Minis running snow leopard for their signage. They haven’t! These things have been here since at least 2012.
Alas, my @rcrpodcast cohorts have finally driven me to order a NABU computer. Should be an adventure, well, if I can find desk space for it (actually).
