I have an HP105B e/w a 10811-60109 oscillator.  It has the same physical 
configuration as all other plug-in 10811s.  It's plugged into the 
00105-6044 board that you mentioned.  This combination was also 
apparently used in the 5061B Cs standard.  You can see it in the 
pictures in the manual.  I also have a couple of the older 00105 
oscillators.  Totally different physical configuration compared to the 
10811 / 6044 combination, but the two are plug-compatible.
