EtherTalk NB Card: Revisions L and M Are Functionally Identical


What are the differences between revision L and revision M of the Apple
EtherTalk NB Card?

As of November 14, 1990, the Apple EtherTalk NB Card started shipping as
revision "M". The revision M EtherTalk NB Card has no functional
modifications or differences from the revision L EtherTalk NB Card. The
revision from "L" to "M" was made because of a process change in
manufacturing and not because of any bug fixes or enhancements to the
card.
