Thank = you, thank you! Here is the Go version of black.c:

package main

import = (
"bitbucket.org/mischief/draw9"
"fmt"
"image"
"log"
"time"
)

func main() {
disp, err :=3D = draw9.InitDraw(nil, "", "black")
if err !=3D= nil {
= log.Fatal(err)
= }
screen :=3D= disp.ScreenImage
rect :=3D = screen.R
black :=3D = disp.Black
= screen.Draw(rect, black, nil, image.ZP)
disp.Flush()
time.Sleep(5 * = time.Second)
= disp.Close()
= fmt.Println("rectangle was", rect)
}

One = minor issue: the window is white after the program exits. Text doesn=E2=80= =99t show until I hit the up and down arrow keys.
