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).

These (and the ones below) are\nmore retrofitted protection\ndiodes, these are present on\nmost C16s I've seen.\nNote that these protection\ndiodes have been added on all\npins going straight to the CPU\nfrom the outside world.

This diode is the one\nAndrew Challis\nrecommends in order\nto let the Datassette\nmotor run only when\none of its keys is pressed.\nWe add a pull-up resistor\njust in case. Install both\nonly when using a 6510\nCPU. (He says FB15 on\nhis page but it's a clear\nmistake.)
