The HB-F1XDJ is an MSX2+ computer released by Sony in 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 two floppy disks 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.

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.

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).

Connections

  • RF output
  • RGB output
  • Mono analog audio & composite video

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.
