replace the capacitor C2 (now 100uF/0.1uF, next to CA3080) by a smaller
value. E.g. 10 nF will reduce the shortest time by 10.

> A151 - install a switch like the new version to select 2, 3 or 4 steps.

center terminal of the switch -> reset input via a standard diode (e.g.
1N4148), cathode (-) on reset socket
end terminal 1 of the switch -> CD4053 pin 14 (LED control for I/O 2)
end terminal 2 of the switch -> CD4053 pin 15 (LED control for I/O 3)
