   Does anyone know of a bridge or router that will allow HP hosts running
   TCP/IP which speak IEEE style packets (802.2 encapsulated) to
   communicate with ethernet style IP implementations?

I've answered Kevin separately, but here is the info for everyone
else:

  1. The old-style HP 802.2/802.3 encapsulation pre-dates SNAP.  It
     uses the SAP originally reserved for IP (06) and uses a separate
     protocol for address resolution (Probe).  All this design was
     done back in 1981-82, when no one but the 802 committee and HP
     were interested in 802.

  2. HP does not encourage new implementations of HP 802 and Probe,
     because there are standard, and thus better, alternatives.

  3. All HP products now support Ethernet and ARP, so no one has to
     worry about the HP 802 encapsulation anymore.  Just upgrade to
     the latest networking bits.
