Inside The 555 V2

its accurate to the old Signetics 555 timer datasheet its cramped but its all here threshold comparator (top left-ish) trigger comparator (middle-ish) flip-flop (top middle-ish) output (top right) reset/discharge (bottom right) ive wired all the pins from the circuit i made to their corresponding pins on the actual chip which is in the bottom left if there was more circuit room all the different parts of the circuit would have been spaced out properly you could remove the 555 in the bottom left and put a circuit in there to test it if you can fit your circuit in the left over space that is but it should work in every way like a 555 chip this circuit as is with the 555 wired up to it like that is like soldering 2 555's together pin to pin lol
