So, got this project due for tomorrow and it says that through a 5pin input, display the one's or two's conplement which is controlled by another pin on two 7 seg displays and when its a negative the first 7segdisplay should be a - or if its a number bigger than 9 it should display a 1. All this with the help of a ROM. Struggling to find a concrete way help would be appreciated. THX
