This circuit generates sequence of pulses in order and times determined by the capacitors in pins 6 and 7 of each timer. The circuit is from an old Mullard (Philips) manual.
Short pulses can be found in this 90's EDN circuit. The load is 50 ohms and the transistors are from that...
Found in an American 1980s documentation, this circuit generates frequencies in the range...
