Hi,
I have acquired new CPU board for my analyzer but it comes from analyzer with 011 option, my analyzer don't have 011 option and I would like to remove this option from software. How to do that? I have replace the U408 memory but this don't help.
Hello piotrekp90,
If you happen to have a service guide for the 8753E lying around, that will be great. In there, we have a procedure to install or remove unprotected options by issuing peek/poke commands to place 1's or 0's into memory. Option 011 is set by the bit at memory location 1619001532. You will need to poke a 0 at this location.
If you don't have the service guide handy, here is a link:

Let me know if you have any further questions.
