Nothing says "80s school computer" than the BBC Model B - If hi-impact was around back then...this is what we'd have been dealing with - a computer you can take apart and repair without the need for specialist equipment too!

This is where my PC journey began in secondary school - We had the 1512s, an 8086 CPU at 8MHz, 512kB RAM, and 2x360k floppy drives - the 1640s had more RAM, from memory, B&W Monitor as well
Something arrived today, from @hmerrett (Retro Wizard Extrodianare)!
The links will be below on what Henry has done, next I'll be retro-brighting, cosmetic makeover and other fun bits. 👍
Thanks dude!

Winmodems..something we all hated with a passion. If you lost the driver disk, tracking down the exact set of drivers to work with these things was a nightmare. And they caused more problems than they were worth

Vor genau einem Jahr habe ich einen Raspberry Zero2 W in Paraffinöl versenkt.
Das Öl sorgt dafür, dass der Prozessor auch unter Höchstlast kaum wärmer wird als Zimmertemperatur.
Seitdem berechnet er mit einem BOINC-Client für die Mathematisch-Physikalische Fakultät in Prag 24/7 Asteroidendaten.
So ermitteln wir die Umlaufbahnen aller Asteroiden und wissen, wo die ihre Bahnen ziehen und auch, ob wir uns Sorgen machen müssen, dass uns einer in Zukunft trifft.
Ein genau baugleicher Zero2 W mit genau der gleichen Software führt genau die gleiche Aufgabe ungekühlt aus.
Und jetzt stellt sich die Frage: Macht perfekte Kühlung einen Leistungsunterschied aus?
Und die Antwort ist: Ja!
Und zwar signifikant! – 5,97 %
So das wäre auch geklärt. 😀
This takes me back....
This brought back a lot of good old memories, so I built a defrag screensaver that runs in the browser.

2 Mondays ago, I used 4 Pis to receive ATV pictures from astronaut @Soph_astro on the ISS. The 1st Pi calculates the ISS az and el, the 2nd controls the rotators on the dish, the 3rd shows the radio spectrum and the 4th receives the picture and plays the audio. @ARISS_Intl
