Description

Computer

The HB-T600 was aimed at the Japanese market and sold to investors as stock trading terminal. It's a MSX2 computer with a specific separate keypad, conceived to make easy and fast data communication.

However, this keypad can be replaced by the classical Sony keyboard from the HB-F500, HB-F700, HB-F900 and HB-G900 machines. It was also possible to buy separately this keyboard under the reference KBD-13.
