Noobsaibot73 (Spain) Wednesday 1st May 2013 Hello Olivier, As far as I know the rear ports and the color of many keys are the difference between HB20P and HB10P. The HB20P has a din (RGB?) port which is not present in the HB10P, but it has a separated yellow, red and white RCA''s which are missing in the HB20P. This what I can remember, but I can be wrong.

Jose Francisco Gomez Otero Sunday 11th September 2011 I made my first BASIC programs with this computer in the later 80''s\ I still have it somewhere at home. I first begun with BASIC but changed to assembly quikly so I explored the inner parts of the hardware.\ The Sony msx HB20P had 64k mapped RAM memory in to banks of 32k one of them started at 4000x0 (hexadecimal address) and could be swaped by software with the ROM memory , that holded the OS. So one could easely made changes to the operating sistem , what I used and liked to do !

SantyB (Spain) Monday 20th September 2010 I played lot of time with the hit-bit 10 computer, it was my first computer and passed hours and hours.\ About the question of the difference between models, it can be that one of it has the function keys in colors (Blue) and stop/pause was red coloured. it was sold in spain

The Hit-Bit 20 is a very basic MSX "1" computer. It looks very similar to the Hit-Bit 10. If someone could tell us the difference that would be nice.

It seems to have been sold only in Spain... The Hit-Bit 20P model has a spanish keyboard, which is strange, as if we follow the Sony naming logic, the Spanish model would have been called Hit-Bit 20S, and not Hit-Bit 20P which was reserved for PAL models which didn't need a special keyboard.

We need more info about this console ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.
