Features

This family of computers has different display characteristics and capabilities on each model. The following table shows the features of the z88dk libraries when run on each machine.

Model Console size Colour Lower case Inverse Custom font UDGs Lores Graphics
Super-80 32x16 N N N N N N
Super-80d 32x16 N Y N N N N
Super-80e 32x16 N Y N N N 64x48
Super-80m 32x16 Y Y Y N N 64x48 (alternate charset)
Super-80r 80x25 N Y N Y Y 160x50
Super-80v 80x25 Y Y Y Y Y 160x50

To display colour using mame, the "Colour" option in the "Machine Configuration" menu should be changed to Composite.

Custom font and UDGs

The font size on the Super-80r and Super-80v is 7x9. However, for compatibility with the other targets, z88dk will pad the specified 8x8 font out with a blank line at the top of each character. The machine will cut off the right-most bit of each character when displaying it.

As a result of this geometry, the lores graphics on these machines is slightly mis-shaped.
