Very basic MSX "1" computer. It is the entry-level system of the Sony MSX range. It has got all the minimum features specified by the MSX 1 specifications: 64 KB RAM, two cartridge slots, 70 keys, etc.
It has no built-in software applications unlike its brother, the HB-11.
It was sold with different colored cases. Red in Japan (only), and black for exportations systems. Like most Sony HB (Hit-Bit) systems, exported systems have a letter at the end of their names indicating the targeted country: D for Germany (Deutchland), F for France, etc...
Juan Jose Velez adds:
These MSX HB-11 computers were sold in Mexico with a Spanish keyboard (also with translated on-computer-printed-info, like the "turn off the computer before inserting or removing a cart" you found near the cart ports) in just one group of stores citywide: a women's clothes boutique called "Superbella".
