All 256 characters

The machine's character set is IBM Code Page 437, 8 × 8 pixels, glyphs drawn 5 wide and left-aligned in the byte, living in ROM at $B800. InitVideo copies it into the video card at power-on. Row is the high hex digit, column the low one — so A is row 4, column 1: $41.

What you can PRINT

PRINT reaches $20–$7E and four control codes — carriage return, line feed, backspace and bell. Everything else it throws away, including every box-drawing and shading glyph above $7E. Those need VideoChroutRaw, which is an assembly-level call.
