These are protection diodes retrofitted\nafter production on *some* C16s I've seen.\nThese seem different from the 1n4148 that\nare retrofitted on p6/p7 on the same board,\nsince those clearly say 1n4148 on their\nbodies, while these have a color coding of\nyellow (thick/cathode), brown, yellow,\ngrey (or light blue?), which... erm, would\nmake them 1n4148 ^___^. Multimeter says\ntheir Voltage drops are 0.555V and 0.561V,\nwhile it says 0.323 for the others (all\nmeasures in-circuit).
