The Juko G7-B reflects a time when expansion slots were a precious resource. Early IBM PCs offered just five slots, some already occupied by memory and disk controllers, making multifunction cards highly desirable. By combining video with I/O such as floppy, serial, parallel, game, mouse and real-time clock functions on a single board, the G7-B freed valuable slots while reducing cost and simplifying upgrades. It was an elegant all-in-one solution for expanding early PCs efficiently.
