Ok the PC way to do it is with either a perculator or just put the coffee in a pot and boil the heck out of it, the amount of coffee per taste. Raw eggs, egg shelss and other nasties including fish skin were sometimes added to settle the grounds. Boiling makes it bitter because it releases the tannic acid, this includes perking it.
Bring the water to a slight boil, let it cool slightly and add coarse ground coffee, keep it warm but do not let it boil. After about 10 minutes tap the side of the pot and pour. It will settle most of the grounds and taste like drip coffee.
Put the coffee in a clean cotton back before steeping and you won't have any grounds.
