352 × 9 bits (for CRT display)
(3) OSD functions
- Screen display : 36 characters × 16 lines (by software)
- RAM : 352 words (9 bits per word)
Display area : 36 words × 8 lines
Control area : 8 words × 8 lines
- Characters
Up to 252 kinds of 16 × 32 dot character fonts

Character colors : 16 colors
Character background colors : 16 colors
Fringe / shadow colors : 16 colors
Full screen colors : 16colors
Rounding
Underline
Italic character (slanting)
- Attribute can be changed without spacing
- Vertical display start line number can be set for each row independently (Rows can be overlapped)
- Horizontal display start position can be set for each row independently
- Horizontal pitch (bit 9 - 16)*1 and vertical pitch (bit-32) can be set for each row independently
- Different display modes can be set for each row independently
