I have a few early 40X2's (before they were refered to as -5v). The pinout I received at the time did not include the SRNQ pin now shown on the new enhanced chip.
Is there a list of all the differences? I have found some of them scattered about i.e. the input types for the pins and the voltage ranges for the main power.
I suspect there are more but it is difficult to know if any given feature is new or legacy.
