The SC-3000H is a simple hardware revision to the SC-3000 personal computer that replaces the original rubber, membrane keyboard out with a fully mechanical keyboard. This is similar to comparable computers of the time, like the Commodore 64. The SC-3000H was released in late 1993 in Japan and would also receive an Australian release in 1994. The computer is available in 3 case designs – black, white and red. Japanese models feature additional katakana characters on their keyboards. Outside of the change to a mechanical keyboard, the system operates identically to the original SC-3000.
