I picked up this clear Sun SPARCstation LX a couple weeks ago. I was told that it was a special machine used for trade shows. Let's take it apart, back up its hard drive with BlueSCSI initiator mode, and start recapping the power supply. Saturday noon EST. youtube.com/live/W6tjUSo...

Revisiting this now that I have a #C64U

Fewer characters available than on a C128 or the teletype so I had to fudge the numbers a bit, but I took the opportunity to add colour!

Also I can turn on turbo mode and have the whole thing generated in seconds by an emulated 64MHz 6502 😀

50 years of KIM-1 and me

retro.hansotten.nl/50-years-of-...

I have collected some KIM-1's over the years. The first KIM-1 in 1978, and now I have nine original KIM-1s, from first edition to Rev A, B, D, E , 2x F, 2xG.

And several reproductions with 6532's as replacements.

🎅Türchen 20: LCD-Tastatur🖥️

An unserem 5150 PC hängt nicht IBM's '83-Key' Tastatur, sondern ein Luxus-Exemplar mit kleinen 14x8 LCD in jeder Taste. Diese zeigen, in Echtzeit und abhängig von Shift/Ctrl/Alt, das jeweils aktuelle Zeichen an.

Has anyone ever heard of a (UK?) journal called University Computing? Know where I could find archives? Long shot, but this paper could contain info that helps us open-source a remarkable operating system developed by the UK MoD in the 1970s and 1980s. Boosts appreciated!

We're going to do it all over again! Very excited to announce RetroFest 2026 to be held at Swindon's STEAM museum on the 30th/31st May. If you'd like to exhibit, just full in the form - and if you'd like to come, why not buy a ticket! They also make wonderful Christmas presents :) - retrofest.uk

The back of a Sphere computer was a mess. Why? There was no "backplane"-- no slots. The whole system was loomed together with 14-connector ribbon cables, and the cards sat in loose slots. Moving the system could easily wiggle out a pin or two somewhere, and maybe the computer wouldn't start up.

This is my Total Microcomputer Model 4000 computer. Technically the last of a rare Motorola 6800 based home computer that was a pioneer in an "all-in-one" computer. Six days left on @bzotto.bsky.social Kickstarter for his book detailing Sphere Corporation here: www.kickstarter.com/projects/bzo...

Yes!! Learn about the quick rise and sudden fall of Sphere-- and then the even faster rise and fall of this mysteriously related Total Microcomputer Model 4000--in this cool book coming soon. Santo has kindly contributed information and imagery to the book. Great stories. Check it out!

Go Computer Now! – The Story of Sphere Computers

The National Museum of Computing at Bletchley held a sale day to shift some of their unwanted stock and raise money for the museum. I went along to see if I could pick up a bargain.

At #retrofest a few weeks ago I really enjoyed the setup @devilishdesign.bsky.social had with an Altair 8800 using a teletype as the user interface. He very kindly printed me off a listing of his BASIC Mandlebrot generator.
