Description
The HB-F1XDJ is an MSX2+ computer released by Sony in late 1988 and was originally sold for ¥69,800. 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.
The HB-F1XDJ was sold with a floppy disk containing graphic and game programming tools. The graphics editor is the same as the one from the HB-F900, but lacks some features. A Japanese word processor can be used, but it requires the corresponding disk from the HB-F1XV.
If the computer was purchased from 1989-02-21 to 1989-04-20 they would also have received the F1 Tool Disk II

Specifications
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. 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).

Repair and modification information
- 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.

- 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)
