Retroprogramming is cool.

@TheHighlander71 Hi! Thanks for trying my Asteroids conversion and for the nice comment. Yes, I mapped the "Hyperspace" button to "joystick down". I know, that this is not a very good solution, but I am not sure, if using e.g. the space bar on the keyboard would be better.

@bmoshix Great forum idea! I tried it today with a 3270 emulator (and a 3151 terminal). Looks like the forum software is running on a Linux or Windows system with a telnet 3270 interface, or is it a mainframe? In either case, very nice idea and interesting program.

I am sorry. The github link was wrong. Here is the correct one: https://t.co/3mWPsk2uR1

I made a little interface program to connect an IBM 3151 ASCII terminal from 1987 to IBM mainframes. The source code and a Windows binary are available on Github: https://t.co/C0PXovZYNH
A video about it is here:

@Georges_Channel Thank you very much, George. Yes, I think I will also port Centipede to the Plus/4 using the hires graphics mode like on the C64. But it might still take some time, unfortunately.

I wrote an emulator of Atari's 1981 arcade game Centipede running on the Atari 800XL. The original game program is directly executed on the home computer. The video hardware is simulated in software. Get the program here: https://t.co/n1fdcuUGSz

Preparing my setup for the Vintage Computer Festival Europe on this weekend in Munich: An Austrian "Mupid" videotex decoder from the 1980s with a little self-written server program, e.g. to browse German Teletext pages or to load and run Z80 machine code on the decoder.

Keeping up with technology…

@ArnoHu Thanks for the link. That's a great read.

Kleiner Rundgang für alle die die Sneak Preview des @Computeum auf dem Donaugassenfest verpasst haben:

[Norbert Kehrer @norbert_kehrer]

@Computeum Der Sneak-Preview war wirklich hochinteressant. Vielen Dank an Josef und vor allem Hans für die spannenden Erklärungen. Mein persönliches Highlight war die IBM 5110, der erste Rechner an unserer Schule. Der "Kühlschrank" ist nur das Diskettenlaufwerk, nicht der Computer! 😀

[Norbert Kehrer @norbert_kehrer]

@Computeum Super! Bin dabei und schon gespannt, was es interessantes zu sehen gibt.

[Esther Schindler @estherschindler]

I do like a good index.

[Norbert Kehrer @norbert_kehrer]

@CommodoreBlog Thank you. Very interesting monitor in the bottom left. Seems to be a Commodore 1702, capable of split Chroma/Luma input. 😉

[Norbert Kehrer @norbert_kehrer]

@Computeum @afachat @Raffzahn Gute Idee! Wie viele habe ich auch 6502-Assembler auf Papier geschrieben, handassembliert (mit manueller Berechnung der relativen Sprungoffsets), und dann die Hexcodes in den Junior-Computer bei einem Freund eingegeben. Nach dem Ausschalten war das Programm natürlich weg :-)

[Norbert Kehrer @norbert_kehrer]

My code was quite GOTO-rich back in 1981. Development cycle: Handwriting it on last year's used calendar sheets and testing it on the computers on display in the department store 60 kilometers away from home.

[Norbert Kehrer @norbert_kehrer]

I just completed day 10 of #AdventOfCode 2022 using BASIC on the Commodore 64. This time a "graphics" output had to be created by driving the beam of a cathode ray tube! Just like graphics programming back in the eighties :-)
