🎅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!

Hello! I'm very proud to announce that my yearslong research project into the lost Sphere computer, corporation, and community has launched a crowdfunding campaign today for a professionally-printed hardcover book, with a compelling narrative and images! www.kickstarter.com/projects/bzo...
Go Computer Now! – The Story of Sphere Computers
A book telling the extraordinary story of Sphere, a 1970s Utah personal computer maker far ahead of its time—until its sudden collapse.

You can’t beat an MK-14 for a wonderful piece of history. I’m really looking forward to getting this one working again 😍

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.

A huge thank you to the sponsor of this video www.pcbway.com

Thanks to @tnmoc.bsky.social for putting on a most excellent jumble sale! I've picked up a couple of projects that will keep me busy for a while 😀

Write once, run anywhere! (1/2)

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.

Woohoo! Microsoft BASIC 2 loaded from paper tape! 😀

Copy of the tape made. Let's try and load it 😟

Going through some old paper tapes and found this. It's version 2 of Microsoft BASIC from 1975. Version 1 was never released to the public which makes this Microsoft's first commercial product and it's not been archived anywhere! Time to break out my tape reader... 🙂

What's the best thing to do on a sunny day at the seaside?
Visit @shortcircuit.org.uk of course!
Join me and my pal Thomas as we poke around a vintage computer "Gallery" and chat to the amazing people behind it.
We also had ice creams and a lovely seaside lunch.

One source for totally lost games is the desk-sized Noval computer by Gremlin Industries.

I just finished going over that portion in my book and it bums me out that none of the software is preserved. There were really advanced arcade and educational games on it.

He may not be a Red Arrow but John does make exceedingly good videos. This one on the OSI Superboard II & UK101 is well worth a watch.
