It is now www.artekmanuals.com
But I fully agree. This is a great resource if you are in to the legacy test
equipment.

==================
Hello Folks!
I turn to you in hope someone can help me.
The old but good signal generator 8640B is by Agilent declared obsolete
and no support available.
The frequency counter in the last production versions, has a Pre-Scaler
P/N 08640-60306 quite different from the "old" one 08640-60168.
The old version have 5 IC's, the new has 6 IC's, 2x 1820-0982, 1x
1820-0736 and the scaler 1820-1003, all four are EECL.
Two remainig are ECL 1820-0145 and 1820-0817.
I need a schematic diagram for this board. Any help on this matter is much
appreciated.
Thank you,
Alf Pousar
