New entry from purist - Project : Radeon R500 will be 20 years old as of 05 October 2025, so it now qualifies for Retro Challenge. The primary/minimal project goal is "draw a triangle on a Radeon R500 via direct memory-mapped hardware register and texture memory accesses". 📷

Microsoft Excel turns 40 today. This is what Excel 1.0 looked like (it was only released on Macs).

#retrochallenge I'm out of the block with my first update: urbancamo.github.io/retrostuff/rc2…

LambdaMikel: Previously, I built a graphics card for the MPF-1B. So far it has done text output and Mandelbrot fractals. For RC2025/10, I want to see a rotating 3D cube on it!
decle is first out of the block: I'll attempt to reverse engineer and document The Drof Computox, an electro-mechanical noughts and crosses machine. It seems to have been built by a hobbyist from telephone exchange parts perhaps at some point in the 1960s.
And we're back for another month of madness! If you want to be a part of RC2025/10 fill in the form for a place docs.google.com/forms/d/e/1FAI…
Can't have too much green! Or can you? Come and see my table at the Retro Computer Festival and find out (and bring sunglasses) computinghistory.org.uk/det/72253/Retr…
This is what I've been up to: installed Solaris 2.6 under qemu and then WordPerfect 6.0/5.2 for Unix - I have a full box including the required serial number!
