I don;t normally like electronic documentation (much prefering it on 
paper...) but that set of CD-ROMs (I don't have a DVD-ROM drive, so I 
bougth the 10 CD set) wsa well worth the money. It's about what you'd pay 
for a couple of manuals at some places... If you like HP calculators and 
small computers, you need these disks.

For larger HP machines, and peripherals (including printers and plotters) 
there's a lot of free scanned manuals (pdf format) on 
http://www.hpmuseum.net.  Of course many of the service manuals are 
boardswapper guides, but I find it quite amusing to read those and then 
work out how to do the job properly :-)
