Well I have asked the Yahoo HP group this question. I have an HP8601A in 
need if a power switch cap or a complete push button power switch.
I have feelers out and about.  maybe some one has an old parts unit or a 
hand full of these switch caps.  The switch is good  just have to use a 
pencil to actuate it.  Any leads greatly appreciated.
Thank you
Hutch
