Apple EtherTalk Card: Revisions "J" and "K" Explained


TOPIC ---------------------------------------------

What is the latest revision of the Apple EtherTalk adapter? Is there a
specific revision required to support the Internet Router and AppleTalk
Phase 2?

DISCUSSION ---------------------------------------------

The latest revision of the Apple EtherTalk Card is Revision "K".

To be assured of good performance when there is a lot of network traffic,
you should use Apple's EtherTalk Card with EtherTalk 2.0. You should use
Revision "J" of the EtherTalk Card. Revision "J" fixed a problem in
earlier revisions that caused data corruption.

When a Macintosh IIcx is used as an EtherTalk 2.0 workstation, then Revision
"K" of the EtherTalk Card should be used. Revision "K" fixed a problem that
caused a Macintosh IIcx with only one card installed not to start.

Both problems occur only in rare instances, but to be safe, Revision "J" or "K"
should be used.
