The grid solves as follows: OPEC.MCGRAW.ABE ASEA.AREOLA.LOX FIRSTLETTER.CRT ...KOANS...DOZE MAO.LYE.PRAETOR OFTHEALPHABETIN CATER..LENA.... KRONA.JAW.TENSE ....NEON..TRIED EACHCOLORSORTED OILIEST.ANI.SPY CRAM...LIARS... EMU.ASRESISTORS NED.WEEVIL.IRAQ ENE.LEMONS.REEL The four unclued Across answers together read: FIRST LETTER OF THE ALPHABET IN EACH COLOR SORTED AS RESISTORS Note that the nine colors represent the nine nonzero digits in the standard color-coded labeling of resistors.
