When it came out, Macs were a mess. They were even beginning to let other people make their hardware. BeOS ran on PowerPC archtecture, so it was like a mac option. Windows was just kicking off win 95 which was a gui shell on top of DOS.
BeOS was the multimedia machine. Everything ran smoothly, and played smoothly, built for speed on light systems while doing multimedia work.
It was too little too late, and Apple would would acquire Next, and windows would start the NT kernel and Win 98 lines that were on the computers at the store.
BeOS couldnt get a foot in the door and the rest is history.
Why Haiku and BeOS now? I guess why not?
But WHY! If those diags are important, then just put them in the local display of the machine itself.
