what the hell im stuck......
 

OK so im still wondering how come ive seen that there is a SE 4port but i always thougtht it was a 6 port? and there is a 6port model starting at 1984 so can anyone explain cuz im so lost.

actually nm i know it has a 6port but others have told me its a 4port..13b?

6 port 13B is correct, yes

The early 13Bs (non-SE, they were somewhere in the 70's) were 4 port.

yea, the old 13b's were 4 port. I think the first 6 port 13b's were the SE ones, i could be wrong about that though.
