Compared to the FC-80, a firmware is included: a spreadsheet named Pasocalc and an assembler/monitor. The same model was available without this firmware, see GFC-1080A.

After booting, you access to a menu with 2 options (Pasocalc and Basic). The built-in assembler/monitor can be launched from Basic by CALL A or _A. You need then to press RETURN to get an intro message and the monitor zone at the bottom of the screen. A new pressing on RETURN displays a specific cursor.

This computer is a MSX1 with a Z80A from Zilog (Z8400A PS) or Goldstar (GSS Z8400A PS) at 3.579545MHz.

All features are common to the standard, apart from one: it has a hole at the right of the cartridge slot to store a lightpen when the pen is not in use. A lightpen was planned in option with its dedicated cartridge, but was never released.
