The Sony HB-F1XDJ is an MSX2+ computer released in late 1988.

The hardware PAUSE button, the Speed-Controller (slow-motion) and the REN-SHA-TURBO (autofire for both joysticks and spacebar) are nice features for playing games.

This model was later replaced by the HB-F1XV with a few minor changes. As with all MSX2+ machines, the HB-F1XDJ was only sold in Japan.

For more info about the application, see Sony HBS-B012D.


One or two floppy disks were provided with this computer:

  • Game Programming Tool Exclusively for HB-F1XDJ with MSX-DOS 1 + the graphics editor Halos created by HAL Laboratory and game programming tools
  • F1 Tool Disk II with a new version of Halos (the color border is different, the fonts screen has been modified) and more game programming tools - actually designed for the HB-F1XV, it was offered to people purchasing a HB-F1XDJ computer or a HBP-F1C color printer from 1989-02-21 to 1989-04-20

It is recommended to press the CTRL key while booting the computer if you want to use these disks, it will help you to avoid memory issues with some applications.


MSX-DOS can't be launched from the first disk as pressing CTRL+STOP when booting will not prevent the loading of the main menu. Inserting the disk after booting and entering POKE &HF346,1: CALL SYSTEM leads to the game programming tools menu. The only remaining option is to copy MSXDOS.SYS and COMMAND.COM to a new formatted disk with the MSX-BASIC COPY command.


The graphics editor is the same as the one created for the HB-F900 / HBI-F900 system as HBS-H022D, but lacks some features. Files created by this tool: .SCR.

Contrary to the professional version, which always requires a mouse, you can use the keyboard, a joystick in port B or a mouse in port A with this version.

This version supports screens 5 to 8.


You get first general explanations ending by a choice between screen adjustment and access to tools menu.

This menu displays the names of all available BASIC files. You can run them or load them and most of them can be interrupted by using CTRL + STOP. You can generally go back to the tools menu with F1 key.

The intro and several tools use Kanji BASIC.

There are 33 options:

  • AC-GEN - Example of collision sprites in screen 5
  • AC-PROG - Dragon Land II (action game)
  • AD-CUT - How to cut a picture in screen 5
  • AD-GEN - Text part of adventure game in screen 0
  • AD-GEN1 - Text part of adventure game in kanji mode

The HB-F1XDJ is an MSX2+ system with two cartridge slots (one at the top, one at the back). The CPU is a Z80A manufactured by Zilog (Z0840004SPC) and the MSX-Engine chipset is the Yamaha S1985. The floppy disk controller chip is the MB89311.

The HB-F1XDJ does not have accommodations on its motherboard for an internal RAM expansion, but it is possible to expand the system's memory by replacing the individual RAM chips with a small PCB (see the link below for details).

Maintenance, Repair and Modifications

  • RAM upgrade (Portuguese)
  • As with many MSX2 and MSX2+ machines with a built-in floppy drive, the rubber drive belt has a tendency to deteriorate with age, preventing the system from accessing disks. A proper replacement drive belt has a diameter of 59 mm, is 186 mm in length, 2.8 mm wide and is 0.4 mm thick.
  • The systemboard has a daughterboard called "HIC-1" which contains three SMD electrolytic capacitors which will leak over time and badly damage the board around it. Please see this thread about replacing them.
  • The systemboard has various ELNA capacitors which will leak over time and need to be replaced. See this thread for more information.
  • Video board diagram circuit (direct download link) (Japanese)
  • Keyboard repair kit for Sony HB-XD/XDJ/XV (Japanese)
  • To fix the slight crackling in FM sound, replace C99 by a wire and C20 by an unpolarized capacitor of same capacity. You can also add an 4.7k resistor between C20 and the sound input but it's not essential. (Source by Niga)
  • Sony HB-F1XDJ upgrade to 512kB (Japanese)
  • 4096kB upgrade kit for Sony MSX2+ (Japanese)
  • Recommended batteries: Lithium batteries or Eneloop (white or cyan).
    Batteries advised against: Alkaline batteries because they leak one day or another.
