Sony CDL5000 CD Library OSL2000 Optical Library

Hi all, sorry for the multiple postings but my head is sore from banging it
on the wall :)

Have the following items being offered to me;

Sony CDL5000 CD Library
Sony OSL2000 Optical Library x 3

I can't find any documentation specs or much else (apart from compatible
software) :/

Anyone have any comments or more importantly information on these items..??
manuals links, what is a resonable price to pay for them..??

Thx in advance...
