CHECK OUT THE WIKI The purpose of the wiki is mainly to allow you to find information on instruments, either from either
- The model number
- The function(s) listed below. Some instruments have multiple functions - for example, the 4195A is a VNA, spectrum analyzer and an impedance analyzer. Therefore the 4195A is listed in multiple categories

Re: Modifying IC socket
I did the NewScope LCD upgrade on my 85662A, 8757A, 8510C, and a beta test version on an 8510B. They are excellent upgrades, especially as one’s eyes get a little older. I don’t recall my 85662A
