Homebrew developers quickly filled this niche, porting several development tools from DVK and UKNC. This led to an explosion of homebrew software, from text editors and databases to operating systems and games. Most BK owners expanded the built-in RAM to at least 64 KiB, which not only allowed easier software porting from more "grownup" systems, but as these upgrades often included floppy drive controllers, creating a one's own disk operating system became something of a competitive sport in the BK scene. Games and demo communities also flourished, as its anemic graphics were offset by a powerful CPU.
