A note for the #RISC_OS folks: From the History of @Arm "The first chip was delivered to Acorn (then in the building we now know as Arm2) on 26th April 1985." That means that in few months it's the 30th birthday of the #Arm2! So let's get some beers ready I guess😎
Oberon is a programming language and a system. It is a successor of Pascal and Modula.. Very strict. You can see a little "Hello World" Down to left. You start things by middle clicking on a text that is interpreted as code.. for example hello.Open.
Oberon , my old friend, Here running on my A1200, #amiga #oberon #oddsystems
Haiku is my favorite OS that runs on X86 pc:s. This is a quite cool feature..

To those of you who will attend: Have a great #RISC_OS show in London today!
RISC OS Developments is pleased to announce the release of RISC OS Direct 5.31, complete with wifi and a JavaScript web browser to deliver what we believe to be the best possible experience of RISC OS on @Raspberry_Pi 4 and below. riscosopen.org/forum/forums/1…
True story!
Calculator and micro:bit hand in hands
More python on TI-nspire CX II-T. It is poking a LUA script in the background that in turn animates the graph. I don't like python, but in this case it is quite fun!
genodians.org/mickenx/2024-0… My Bristol demo, code only for the brave.
I will be doing a presentation to ROUGOL over zoom on Monday about 64bit RISCOS. The contact details for it are here: rougol.jellybaby.net come along if you’re interested in what might be done to make a version of RISCOS that uses modern ARM architectures.
RPCEmu for MorphOS is now updated. Hostfs now works for both/read and write. More fixes will follow soon. A little annoying bug is that enter is pressed from start.. but a little escape in task window stops that.
