The HB-F9P was unusual in the sense that it did not come with a built in floppy disk drive, instead it had a built in software suite "Memovision" that would run automatically unless a program cartridge was inserted in the cartridge slot or the GRAPH key was pressed during booting.
Memovision could store data on the special HBI-55 (battery backed RAM) "data cartridge" [2] that Sony originally had developed, for their HB-55 and HB-75 MSX computers. These systems contained a simple built in program called the "Personal Databank".[3][4] Memovision was a continuation of the same idea, but much extended, as it contained stuff like a (birthday) calendar with alarm system, a "family databank" (a combination of a text editor and database) a built in calculator and a timer and time calculator, all rendered in pseudo 3D style.[5]
