Lesson 2. The turret: four pens

2.2. Idea: the motor is two flip-flops in a ring
2.3. Idea: a quarter turn = 6 steps
2.4. Idea: two two-bit counters
2.5. Idea: turn until they match

3.1. Idea: the card has three addresses
3.2. Idea: the decoder — «no bit differs»
3.3. Idea: writing to a register

Lesson 4. A program with a menu: seven pictures
4.1. Idea: the whole program is three addresses
4.2. Idea: «home» by the limit switches (lines 900–940)
4.3. Idea: a straight line from steps (lines 1000–1090)
4.4. Idea: colour and waiting (lines 1300–1330)
