HB-F9P

The HB-F9P was a Sony MSX2-computer, launched in 1985. The abbreviation HB stands for Hit Bit.^[1]

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]

Variants

Of the HB-F9 there were many different localized variants produced:

HB-F9P, with QWERTY-keyboard layout was designed for the PAL-standard, and meant for European countries, except Germany, France, Spain and the former Soviet Union.
HB-F9R, had a Russian keyboard.
HB-F9D, had a QWERTZ-keyboard for the German market
HB-F9F, had an AZERTY-keyboard for the French market, and was designed for the SECAM-standard.
HB-F9S, had a modified QWERTY-keyboard for the Spanish market.
