How did ICMB work before the era of computers...

Without GPS they could only use gimbals, gyro, IRU etc... and probably initial icbm only had a single fixed target and couldnt be retargeted before launch... so at least it had a fixed launch position and fixed destination hardcoded to make calculations static

but what about accounting for wind changes, temperature variations, other factors... depending on when it launched the moon would be in different locations and slightly alter gravity etc...

without computers how did it keep track of this and if it just used dead reckoning of sorts wouldnt that be horribly imprecise? what if an rocket engine failed? how would it calculate to compensate??
