GPIB is basically the same as HP-IB and IEEE-488.  Its use lasted for  
a fair while in certain scientific instruments (new devices were  
being produced into at least the mid '90s).  I think it generally  
used +5v signaling due to some IEEE-488 to Centronics parallel  
adapters that I have and the way the interface is implemented in  
Osborne computers.
