4 Many cartridges uses epoxies for ROM, RAM and mapper. Few cartridges
5 uses discrete parts. Other functions are various though the memory
8 The mistake of an old document is an etymology of 'namcot 106'. I have
9 seen mapper IC with 163 (well known chip), 129, 175 and 340 for #19.
10 I have never seen labeled IC with '106'.
11 '106' is informal virtual name, and the relic of old emulators.
