Decoding transmission ID number

Erkka gave me the answer below when I asked about a specific transmission. Anybody know of a more generic answer that explains all the possible values?

12= LSD, but what is non LSD?

***** numbers/letters aren't aligned, so count if you need to.

G28/11 12 11F05121
123456789ABCDEFGHI

1 = manual gearbox
23 = 928
56 = 11 is US '85-86
89 = 40% ZF LSD
B = transmission for 8 cylinder car
C = 5-speed
D = model year, F = '85
EFGHI = serial number with transmission type and MY,
first US box for '85 was 5001
