Wie schon angekündigt sind die Fotos samt #ROM #Dump des #Schneider #BTX Moduls für den #CPC jetzt auch auf meiner Webseite und im CPCWiki verfügbar. Ich schaue mal, ob ich die Tage auch nochmal das Handbuch scanne und online stelle. #Amstrad #Bildschirmtext

I just released a scan of the SAA5350 User Manual that I scanned a few years ago. https://archive.org/details/user-manual-eurom-saa-5350-issue-1-provisional-february-1988-6-1

Thanks to @Andreas_SuH1912 for lending it to me and getting a copy back in the 80s :P #BTX #Bildschirmtext

I spent a good hour writing some code in Common Lisp - Specifically, I wanted to serve Websocket connections from my Bildschirmtext server.

That reminded me of how powerful CLOS is. As my server works with (binary) streams, I needed to make the Websocket into a stream. All it took was a little multiple inheritance and a handful of methods to make things work.

Die neuen Medien von 1983 füllten damals ganze Bücher ...

(Themen u.a.: Formulare für das Bildschirmraster, Zubehör und Kosten für das BTX-Angebot)

This is the #MUPID C2A2 computer, made in Graz, Austria. It was released in 1982 but never became super popular. It is not only a standalone computer, but can also function as a terminal for #Bildschirmtext, a teletext-based dialup information system similar to the French #Minitel.

This particular unit came from Austria and was passed on to me via a chain of friends over the last month or two. It certainly appears well-used! It is to be donated to the #HomeComputerMuseum in Helmond.
