Description
The Sony HB-F750 is a computer that has never been released, and only shown in a few museums and at exhibitions.
It has remained at the prototype level, but it is a proof that like Philips and Toshiba, Sony was a pioneer in introducing the CD-ROM to computers.
It appears based on the HB-F500 and HB-F700, with the addition of a built-in CD-ROM drive. The cartridge slots have been moved at the back of the computer.
It has a QWERTY Japanese keyboard with ANSI layout for kanas characters and half of the keys with kanas in gray. The case is in white color.
