It does not differ at all - it is essentially the same (only the
connector in the PET is different).

The problem is that GPIB defines only low-level communication details, a
bit like TCP/IP. What you build on top of that, the application
protocol, is up to you. So it's like two computers with a TCP/IP stack,
but one speaks HTTP and one TELNET - even though the underlying
low-level protocol (TCP/IP) is the same, it won't allow them to
communicate unless they agree on the same higher level protocol.
