Re: 8720D firmware update
Ok. It sounds like little is to be gained. If I read you correct I don¡¯t need to worry about going from 6.10 to 6.14. ? It says option 010 at bootup Thanks Dave

Re: 8720D firmware update

I will doubly recommend that you have very steady hands and a decent microscope (I used 60-100x Leica binocular), handy if you are going to open the YTM. Before you open it check the small pc brd that

Re: 8751A floppy drive
Hello Ovidiu, have a look at https://www.rudiswiki.de/wiki9/HxCFloppyDiskEmulator I replaced a Sony *MP-F52W-30* with a Gotek Floppy Disk emulator in a HP1652B Logic analyzer. Maybe that could help.

Re: Need Help Diagnosing an HP 8559A Spectrum Analyzer
