Alternative ESIX manuals?

[Steve Godersky]

I am buying a UNIX System V flavor called ESIX
(development version for a 386).
I am having trouble affording the Manual Set which runs $300+
Are there any equivalent manuals that will provide a good
level of support which I can buy individually for less?
I am thinking particularly of manuals for Xwindows, Sys Adm,
network support and driver support.
Or, are the ESIX manuals worth it and/or irreplaceable?
I use System V at work but I still have much to learn,
and I'm no great C programmer, either.

Replies should reach me addressed to Steveg @iii.com

Thanks to you all.
