LN has observed (not sure if always true): “cmos…yamaha part starts with a 3 (nmos parts start with 2)”

According to Tiido and others, Yamaha is a fabless vendor, and has other chip manufacturers do all of their silicon fabrication and packaging. Examples being Fujitsu, Sharp, Hitachi, ROHM.

Datecode

Yamaha Datecode/Markings:
1981-1989 'old style': (may have been used very briefly in 1990)
yM ww Ll r
1990+ 'new style':
Yyww MLlr
Y = year most significant (9 or 0 or 1 for 199x or 200x or 201x)
y = year least significant (2 = 1982, 3 = 1983 ... etc ... 9 = 1989) (0 = 1990?)
M = Manufacturer code, see table below; old style and new style chips have different tables
Ll = lot code/batch code?
ww = week within year
r = die revision

Fabs

'old style' markings:
1 = 
2 = Sharp?
3 =
4 (= L) = Hitachi 2
5 = Sharp [probably = I below]
6 = Hitachi
7 =
8 = Hitachi or ROHM (NDIP)?
X =
Y = Hitachi?
Z = Fujitsu
'new style':
A = Sharp 2
C = Hitachi 2a
D =
E = Hitachi 1
F = Fujitsu
G = Hitachi 1a?
H = Sharp 1
I = Sharp [probably = 5 above]
L (= 4) = Hitachi 2
O =
Z = Fujitsu [This is interesting, possibly a printing error which should have been F but they printed a Z instead?]
