Description

Computer

The Sony HB-701 is the first HitBit Computer that can be equiped with a built-in floppy disk drive (see HBD-100). This machine was aimed at the Japanese market and available in black on front and pale gray.

The only difference between the HB-701 and the HB-701FD is the drive, which is build in the HB-701FD. Front and back of both machines are exactly the same, with only a little difference on the left front, corresponding to the location of the drive.

The machine has a separate keyboard without numeric keypad.

Firmware

After booting, you can

  • press F1 when "MSX" is displayed in pink to go to BASIC
  • select "HITBIT ART" and press F1 to launch the built-in firmware HitBit Art, a graphic and title editor.

The firmware menu presents 7 options in Sony advertisements (final product is different):

  • BASIC
  • Design (F2 for dynamic part - F1 to back for static part)
  • Telop
  • Sprite
  • Story
  • Action
  • File

Notes:

  • The Sprite and Action options can only be used with the HB-701FD or HBD-100 floppy disk.
  • When the HB-701 is extended with the HBD-100 drive, it will work like the HB-701FD (the ROM version of HitBit Art becomes useless, you can use only the improved version, provided on floppy disk)
