       What is the "best" version of public domain telnet that runs
       with LocalTalkPC cards?   Where can this be ftp'd from?
    
    Not sure.  Katie Stevens of UCDavis wrote a localtalk packet driver.  I'm
    not sure if it's interoperable with your equipment.  But if it is, then
    you can use it with any TCP/IP package that supports the packet drivers,
    i.e. NCSA Telnet, CUTCP, KA9Q, FTP, Win/TCP, etc...

When she got the 'type' value from me for the driver, she mentioned that it
was 'real Appletalk' as opposed to 'fake Ethernet over Appletalk'.  Thus it
requires software which understands Class 5 packet formats & demultiplexing.
Of the packages Russ mentions, KA9Q is the only one I'd bet on.  PC/TCP 2.04
only understands Class 1 (Ethernet).  2.05 (ships this week) will also
understand Class 3 (802.5), Class 6 (SLIP), Class 11 (RFC 1042 on 802.3) and
Class 13 (IP over X.25) Packet Drivers, but not Class 5.

As far as compatibility goes, I believe she used a standard software
interface to IBM PC Appletalk drivers (ATALK.SYS?) which is supplied by a
number of board vendors.  If I recall this correctly, you probably can run
it on most of the available cards.

As a final test of my memory, am I correct in believing that nobody has
ever written an RFC describing standards for sending IP over Appletalk?
If so, somebody should...  I would like to know more about it, since I
am adding a "summary of encapsulation and demultiplexing" for each of
the supported Classes in v1.10 of the PDS.
