I wouldn't fancy wiring this connector up😱! Inside the Hirose connector of the 100 way #Quantel Dylan cable that connects your Quantel Editbox, Henry or Hal to it's Dylan disk array.

In 1968, Douglas Engelbart revolutionized computing by showing the mouse, hypertext, and collaborative computing in "The Mother of All Demos". Most of his ideas are now part of everyday computing, but one device—the keyset—failed to catch on. Let's look at Engelbart's demo and the keyset. 1/N

I just parked my "prehistory of a technomad" on YouTube, a little under 7 minutes. Plan is to do additional videos spanning the whole adventure epoch (including Deep Geekery), with the main body of the story continuing in text. youtu.be/-RzBPcDYCF0 (And I'm back to work on Substack!)

Working on something today. I've been doing a lot of recapping recently and was getting tired of Googling pdfs. mightyohm.com/wiki/referen...

Cleaning under the hood of our PET 2001

For once I actually knew the computer @tayloramyshow.bsky.social are checking out in the latest episode, but that doesn't make it any less exciting to see them in my feed! www.youtube.com/watch?v=4VX2...

it took a month, but i've reverse engineered this IBM MCGA gate array chip. 17,000 transistors. 768 gates. over 1200 nets.

New video! Dramatically improve microscope resolution with an LED array and Fourier Ptychography youtu.be/9KJLWwbs_cQ

Ah, now that's the good stuff.

I'm a simple woman who enjoys drag soldering

This is a rare beast, it's my Arraid EID-1C SMD Disk Emulator. It's configured to emulate a Fujitsu 14" M2294 330Mb SMD 'Winchester' disk used on my #Quantel DPB-7001. Originally it would have a 3.5" SCSI disk, but this one uses a SCSI CompactFlash drive instead 🤘

Tradera skulle verkligen må bra av några konkurrenter nu när både säljare och köpare betalar avgifter på auktionerna.

Some screenshots taken with FUJI RDP3 film🥹

The F-4 fighter plane used a three-axis attitude indicator to show the plane's orientation. (Like an artificial horizon with a third axis.) @curiousmarc.bsky.social, @tubetime.bsky.social, and I restored a damaged indicator. The video includes burning slip rings: www.youtube.com/watch?v=snP_...

What is the origin of the word "mainframe"? Digging through archives, I traced it back to 1953. The IBM 701 computer was built from "frames": power frames, a storage frame, a drum frame, and the main frame. This 1953 drawing from the Installation Manual shows the dimensions of the "main frame". 1/n

#TIL That this site is actually what became of Jack Dorsey's 2019 tweet about Twitter working on an "open and decentralized standard for social media." I'm shook!

New Video: f/0.38 camera lens made with oil immersion microscope objective www.youtube.com/watch?v=DQv0...

new toy: an Olympus microscope! this'll be good for looking at chips. but it's used and will need some work to clean it up. I'll update this thread as I go through it.

Following yesterdays post here is a #Quantel 2077-76 Backstore 2 card. Containing 768Mb they are used as image storage on the Graphic Paintbox 2 (1995) which i could operate with 3 of these cards.

Tuned up my ActionStation XT300 today. This was the dream machine for every 80's hedge fund manager. Sell sell sell! Buy buy buy! Dual phone line, speaker phone and 1200 baud modem. Can you tell from the pictures what was wrong with it?

Bluesky feels like old Twitter in too many ways.

Videos on Bluesky? So does this work ok? #nordic

today we fired up the old Xerox Alto (the earliest computer with a graphical OS) and dumped a disk pack that we hadn't imaged before.

I've renewed PAULANDREWMITCHELL.COM for another 9 years. www.youtube.com/watch?v=KSWq...

Blows me away NOS hardware shows up 40 years later. I suspect for over half that time it had almost negative value.

I have before me 2 DEC AlphaStation 200 4/233 systems. I’m told one works and one does not. I believe they have OpenVMS installed on them and that they were running some high-availability application (I also have the shared external disk enclosure).

I REALLY need to do something with my AT-Once Vortex card for my Amiga. It's the 286 PC that plugs into the 68000 socket on an #Amiga. I have owned it for years and never gotten around to trying it out. I need more hours in the day...

Glorious 16K of core memory in a functioning PDP-8.

several months ago, i had a chance to get hands on (well, gloved hands) with a real Apollo DSKY, which is what the Apollo astronauts used to control the famous AGC (guidance computer). take a look at Curious Marc's first video in the series. www.youtube.com/watch?v=JB4x...

Having a lot of fun casting replicated freeform optics from a CNC & post processed tool. I wanted to save money coating, so I tried a sterling silver target in the sputter coater and the results were awesome. A little silver made it around my stencil, but it's easy to buff off.

I'm being followed by so many strange accounts. I can't help but to wonder if this platform being drowned in bots?

As part of the 20th anniversary of BBS Documentary's release, I've ripped the 3 DVDs that were included in the project and have them hosted at Internet Archive. These ISO files can be played in the VLC player like DVDs, and include all bonus features, subtitles, etc. archive.org/details/BBS_...

Recently picked up this NOS 70's car computer for giggles. It's surprisingly advanced! The copy is really fun and the box shape is well thought out for point of sale displays.

Oh, hello old friend. Glad to see you working again. We owe you so much.

2025 is the year of the 20th Anniversary of BBS: The Documentary. I'll be doing a round of updates, events and even a sale of some old copies I found while moving offices. Let's enjoy what some people say was my only good documentary!
