P: The original PowerBook 100, 140, and 170 were replaced by the PowerBook 145 (updated to the PowerBook 145B in 1993), PowerBook 160, and PowerBook 180 in 1992. The 160 and 180 having video output allowing them to drive an external monitor. In addition, the PowerBook 180 had a superb-for-the-time active-matrix grayscale display, making it popular with the Mac press. In 1993, the PowerBook 160 was the first PowerBook with a color screen, later followed by the PowerBook 180. In 1994, the last true member of the 100-series form factor introduced was the PowerBook 150, targeted at value-minded consumers and students. The PowerBook 190, released in 1995, bears no resemblance to the rest of the PowerBook 100 series, and is in fact simply a Motorola 68LC040-based version of the PowerBook 5300 (and the last Macintosh model to utilize a Motorola 68k-family processor). Like the 190, however, the 150 also used the 5300 Integrated Drive Electronics-based logic-board architecture. From the 100s 68000 processor, to the 190s 68LC040 processor, the 100 series PowerBooks span the entire Apple 68K line, with the 190 even upgradable to a PowerPC processor.

P: In the final week of the season, the Bears played their second game against the Lions with a spot in the playoffs on the line. The Bears fell behind the Lions after the Bears drive stalled, and Jason Hanson kicked a field goal. Chicago then struck back, with Jay Cutler throwing a swing pass to Earl Bennett, who ran 60 yards for the touchdown; the pass is the longest completion of the season for the Bears. On the eventual kickoff, Joique Bell fumbled, and the Bears scored on a field goal. In the second quarter, Lions quarterback Matthew Stafford fumbled, and the ball was recovered by Julius Peppers, who reached Detroit's 10-yard line, and Matt Forte later scored on a one-yard run. The Bears recorded another takeaway when Tim Jennings intercepted Stafford and returned the pick to Detroit's 23-yard line, and the Bears scored another field goal. Detroit scored the final points of the half on Stafford's 25-yard touchdown pass to Kris Durham to make the score at halftime 20-10 in Chicago's favor. In the second half, the Lions scored again on Stafford's 10-yard touchdown pass to Will Heller. The Bears then had to settle for Olindo Mare kicking another field goal after Cutler failed to connect with Brandon Marshall. Chicago later had to kick another field goal when Cutler again failed to connect with Marshall. The Lions then drew within two points when Stafford threw a nine-yard touchdown pass to Brian Robiskie. However, Detroit would fail to score again and keep Chicago from running out the clock. With the win, Chicago eliminated the New York Giants from playoff contention, but the Bears would also miss the playoffs after the Vikings defeated the Packers 37-34. The Bears ended the season with a 10-6 record.
