Re: HP-8753E Options Activated

Hmmm have you unprotected the EEPROM ?? the E has the new flash based CPU board there is a little switch on the board that you have to toggle to remove the write protect.
I have fixed and upgraded well over 100 8753 and 8720 VNA when I was working at tucker and I don¡¯t recall any instance when the option codes did not work

I did not see any reference to the 8753E Series on Yahoo Groups. ?I did see some reference to the earlier versions to include those provided by Marcus.?
With regards to the Option Codes, I did get options code for both CPU¡¯s from Cesar. Both of them would not take these codes. This issue still puzzles me. I could understand a hardware fault for one not taking it, but two makes me thing
some of the units were locked down somehow.?
