Diodes
After the resistors are installed, move on to the diodes. There are only six diodes on the
Digital Board, and they’re all of the same type (1N4148), so it’s not a terribly large job.
If you don’t have 1N4148s, 1N914s will work fine. Make sure you install them in the
right direction! The silkscreen will show where the cathode goes.

Capacitors
There are a number of capacitors of various values. Most of them are non-polarized.
There is only one polarized capacitor on the Digital Board – C17. When you install it, be
sure to do it in the right direction. The positive lead of the cap will go into the square
pad, which is also marked with a “+”.
