# Bus Expansion And The QL

Almost from the beginning, QL’ers realized the need for bus expansion. A company by the name of QUEST was the first to advertise a bus expansion system that included additional memory, disk drives and an OS-9 type operating environment. I’ve never seen one in person, but have been told only a small number were sold and the OS-9 operating system was never realized.
