I Use your BBC micro to draw a digital clock. Produce the special large characters for the digits and use a colon to separate them. Your clock can be made to keep correct time by using the internal clock of the Model B (see the user guide). II Make a program that tests the Morse Code proficiency of the user. The data for the program will be a paragraph of text, which the Model B should translate into Morse and then print out by means of dots and dashes using the teletext block graphic characters. It can also use SOUND to simulate the sound of Morse. Your program should have a variable rate of production of the code so that the speed of the test increases as the user gets more proficient. III Draw a set of International Road Signs. Your program should draw the background of the figures, such as red triangles, and then use your own special routines or the programs of chapters 5 and 6 to finish off the foreground.
