[Amps] HP 48V power supplies

[Bill Turner]

Does anyone have a source for data sheets and/or schematics on the 
HP 48V 3000 watt power supplies which were recently discussed here?

I googled some sources which want some personal info including credit cards
but nothing else. 

I do have the http://endless-sphere.com/forums/viewtopic.php?f=7&t=32829
website which is helpful with pinouts, but I don't see any links to what I
need. 

Any ideas?

Many thanks,

Bill, W6WRT
