Assuming yoy mean the 5155, it uses the Berg connector inside. 2 of the 
pins (ground and composite output) go to a twisted pair cable which goes 
to the monitor. 

The repaining pin on the Berg header is +12V IIRC. This is not used in 
the Portable PC (the monitor is connected directly to the PSU). I always 
assumed this was a handy power feed for an RF modulator should you want 
to use one with a CGA card.
