A very crude calculation: * Two 8-bit ports with direction pins: 2x2x8 = 32 * One 8-bit serial port = 8 + some unknown overhead * Two 16-bit counters with preset = 2x2x16 = 64 * TOD clock with alarm: 2x28 = 56 * Interrupt logic = unknown, but I would assume at least 8-16 That is already way over 128.
