Description
Computer
The Sony HB-11 is the last MSX1 computer released by Sony, aimed at the Japanese market. It is called "HitBit U" (U for University?) and is dedicated to students.
The case color is available in red or deep blue. The power supply is buit-in.
The design is intermediate between the HB-201 and the HB-10, as only the pause button and the carrying handle have been removed.
A retractable stick is build in the middle of the cursor keys, which can be used as joystick. As on the HB-501, the back of the case has a location to store the stick during transport.
The HB-11 is one of the rare MSX1 computers having a Kanji-ROM Level 1 (JIS1). It is even mentioned on the box.

Firmware
The firmware is launched automatically when you boot the machine.
The Personal Databank of many Sony MSX1 computers has been replaced by a firmware with 2 applications and a global menu with 3 options:
- BASIC
- English-Japanese Dictionary created by the Stratford Computer Center Corporation
After choice of a printer, you access the main screen on which you can input English words. If the entered word is not found in the dictionary, a list with all words starting with the first letter will be displayed.
By pressing ESC on the main screen, you can go back to the menu.
- Japanese Word Processor - Word Land Sentence II with kanji conversion dictionary of 3900 words (was also sold separately as cartridge) - see Sony HBS-B003C for more info
From MSX-BASIC, you can
- start this firmware with CALL HITBIT or _HITBIT
- use 7 alternative fonts in SCREEN 1 with the extra BASIC instruction CALL FONT or _FONT
Easter egg
If the P key is held during boot, an easter egg is started (using one of the alternative MSX-BASIC fonts) with the list of the development team.
The S key can be used to mute the sounds of the firmware boot animation.
The firmware also contains a hidden text: "A Yellow Panther Production MCMLXXXV", what seems to indicate that it was made by the same coding team as the firmware of the HB-F1 and HB-F1II MSX2 computers.
Software
A tape "Patsy Duck's Card" is provided in addition to this firmware, it contains 50 examples of templates.
