You didn't miss much. SL/IP was a pain. Writing modem scripts to drive
the serial links first before hopefully at the right time, the two
ends are ready to just try sending encapsulated IP datagrams without
any negotiation, and if everything is happy, things mostly kinda
worked. PPP added negotiation and handshaking.

If you just want data transfer, it would probably be better to go more
low level, like serial communications, xmodem/zmodem/kermit over
serial links. Or tar data to a file/floppy image, and mounting the
floppy back and forth. Kermit was awesome (and while I don't use its
data transfer capabilities, I still use it as a terminal command line
on my current OSX desktops/laptops. 

Forget networking unless you want an excercise in just getting the
system online and talking on a network.	There have to be way easier
ways to	transfer data like above. Or even writing the basics of	a file
system level FUSE driver seems easier than trying to get anything modern
to talk SL/IP

Its highly doubtful you'll find anything in OSX or Solaris. By the time OSX
came out, PPP was an old man and well used. Think more like OS6 for
MacTCP 1.0 and SL/IP.  Of course, you had to obtain MacTCP in the first
place. We usually sent customers to the book store to find
such-and-such book that had a floppy with it on it with MacTCP in it.
cslip was only written for SunOS 3 + 4. Again by the time Solaris was
written/actually usable, PPP had long taken over.

If you want a whole long history of Mac Networking http://www.applefool.com/se30/

If you want to get Cslip for SunOS 4.1.4, they still have a FTP site 
ftp://ftp.ee.lbl.gov/cslip-2.7.tar.Z

It looks like WindowsXP	may still have had SL/IP in it?

If you had a Cisco router (virtual? hardware?), and connect up some
serial ports, a classic IOS version may let you do SL/IP.

I found better search strings including both slip and tcp in the query.
Once PPP was usable, it took over in a flash.
