    Inexplicably, all three PCjr machines work.

    I guess I gotta get some way to get more software onto one of these. Looks like it's either jrIDE or a Gotek with HxC firmware...but, since these don't have memory expansion already, it's probably worth going with a more expensive jrIDE for the 1MB memory.And, since the disk drives actually work, I kinda hate to swap them for a Gotek. I have Racore expansion boxes for a second disk drive slot, but they're all incomplete, missing parts I can't even identify or find references for.

    Hello World in C Without Linking in LibrariesIf there’s one constant with software developers, it is that sometimes they get bored. At these times, they tend to think dangerous thoughts, usually starting with ‘What if…’. Next you know, they have gone down a dark and winding rabbit hole and found themselves staring at something so amazing that the only natural conclusion that comes to mind is that while educational, it serves no immediate purpose.The idea of applying this to snipping out the <stdio.h> header in C and the printf() function that it provides definitely is a good example here. Starting from the typical Hello World example in C, [Old Man Yells at Code] over at YouTube first takes us from the standard dynamically linked binary at a bloated 16 kB, to the statically linked version at an eyepopping 767 kB.To remove any such dynamic linkages, and to keep file sizes somewhat sane, he then proceeds to first use the write()function from the <unistd.h> header, which does indeed cut out the <stdio.h> include, before doing the reasonable thing and removing all includes by rewriting the code in x86 assembly.While this gets the final binary size down to 9 kB and needs no libraries to link with, it still performs a syscall, after setting appropriate register values, to hand control back to the kernel for doing the actual printing. If you try doing something similar with syscall(), you have to link in libc, so it might very well be that this is the real way to do Hello World without includes or linking in libraries. Plus the asm keyword part of C, although one could argue that at this point you could just as well write everything in x86 ASM.Of course, one cannot argue that this experience isn’t incredibly educational, and decidedly answers the original ‘What if…’ question.youtube.com/embed/gVaXLlGqQ-c?…hackaday.com/2025/10/29/hello-…
