Chloe, you are a fount of obscure but useful information.

Thanks wellington.

Some of the article doesn't translate too well. I've tried to verify as much as I can. This is what I have so far:

G80-xxxx xxxxx

Keycap technology:
H two-colour molding
L laser printed

Stem:
A black (G80-3000) or brown (G80-5000 HAMPO /02)
C black (G80-3000LCMPO)
E
F blue (G80-1800HFU)
K brown (TBC)
P black (G80-11900 LPMEU-0)
Q white (G80-3000 LQMDE)
R black (G80-8113)  
S blue (G80-3000 LSCGB)
T black (G80-11900 LTMEU-0)
U black (G80-3000)
V white (TBC)
W blue (G80-1865 LWNEU-2)
X brown (G80-1865 LXNEU-2)
Y red (G80-3494LYCUS)

Win key:
A
B no barcode decoder (G80-8200)
C Combo (G80-3000LQCDE-0. USB, no n-key rollover, has Windows keys)
D USB bus-powered hub, four downstream ports
E  
M 104/105 keys
N n-key rollover without key lock technology (G80-1865 LXNEU-2), USB connector

Layout:
US, EU, JP, GB, UK, DE, FR

Win key: M representative of whether there is a key WIN, WIN is the key M, is not A (this applies to the old version of the keyboard), the new version of the C key on behalf of the Combo; N on behalf of the N-Key-Roll-Over without key lock technology.

I'm not sure what means. Both G80-1865 have Windows keys but there is only N in the model number for n-key rollover.

Combo means that the board is both USB and PS/2 (via adapter).

Thanks lowpoly.

I just found this pdf which explains why the stem letters are different for the G80-11900 when they both have black MX:

G80-11900 LPM
PS/2-compatible
PS/2 keyboard

G80-11900 LTM
RS 232 and PS/2
AT and PS/2-compatible keyboard
