[Amps] Anyone got programming manual for HP 70000 series?

[Dr. David Kirkby]

A bit off topic, but does anyone here have a programming manual for an 
HP 70000 mainframe? I need to program one which is fitted with bits for 
a spectrum analyser - RF section, IF section, display, local oscillator 
etc etc.

I can't find the programming manual on the Agilent site. Google seems to 
find one at

http://dsnra.jpl.nasa.gov/newdocs/manuals/MMS/70900_progrm.pdf

but that link is dead for me. If anyone can retrieve the pdf, and could 
forward me a copy, I would appreciate it. It's remotely possible this 
site  will not accept connections from the UK, but more likely it is down.
