      If I may suggest an alternative introductory sentence-

      I would replace\
      "The Gundam RX-78 was originaly a very popular manga animation movie from the 80''s. Bandai then marketed a personal computer under this name..."

      with\
      "The Bandai RX-78 was named after the titular mecha from the 1979 anime series Mobile Suit Gundam"

      or something along those lines.

The Gundam RX-78 was originaly a very popular manga animation movie from the 80's. Bandai then marketed a personal computer under this name...

Little is known about this small computer. Since the Gundam Rx-78 was only sold in Japan nearly all the information currently comes from Japanese websites.

The capabilities of the RX-78 were not bad at all for 1983, and the space between the keys offered the possibility to use keyboard overlays with games or applications, except maybe for complaints about the poor keyboard quality.

It appears that there were two cartridge slots at the back of the system. One slot was often used for the BS Basic programming language and the other could be used for special expansion cartridges (to connect a printer for example).

The BS-Basic cartridge was also equipped with connectors to plug a tape-recorder into the RX-78.

While games were the main software developed for this computer an asian brand word processor was also available.
