Spare Parts on an MDD

Symptoms/Issue

I am trying to swap fuses/DMX chips on my MDD but I don't know where to locate the spare parts on the board.

Description

U1 [DMX Transceiver] is responsible for all incoming data. Use U16's spare chip as a replacement. 

F2 - F12 [Data Fuses] are responsible for individual outputs. Use F4 or F7 to replace any of these fuses.
