The ROMs or PROMs must have the correct code for converting the data from the NE5037 -used as address for the ROMs or PROMs-to the appropriate segment driver codes. The displayed amount could easily be converted to degrees Fahrenheit, ?°F, by the controller of (0-63 ?°temperature sensor) or through the (P) ROMs. When doing this, a third (hundreds) digit(P)ROM and display will be needed for displaying temperatures above 99?°F.
