Sony Hit Bit HB-101

The Sony Hit Bit HB-101 was a compact MSX1 computer with a distinctive low-profile wedge case. It retained 64KB of RAM and Sony’s Personal Databank approach while making the machine easier to fit into a domestic television setup.

Japanese and PAL HB-101P versions supported the standard MSX software and cartridge library. Colour options and matching Sony peripherals made it one of the more design-conscious early MSX systems.

Notable Features

• Compact wedge-shaped redesign of Sony’s MSX1 hardware.
• Retained 64KB RAM and Sony data-cartridge support.

Historical Significance

• Showed Sony applying its consumer-electronics styling to the standardised MSX platform.
• The related HB-201 refined the same design for later markets.

Collector’s Notes

• Japanese and PAL models require appropriate power and display equipment.
• Case colours and bundled peripherals vary without changing the core computer.
