       <b>Zilog eZ80Acclaim! Microncontroller</b>.
-      This port uses the ZiLOG ez80f0910200kitg development kit, eZ80F091 part
-      and the Zilog ZDS-II Windows command line tools.
-      The development environment is Cygwin under WinXP.
+      There are two eZ80Acclaim! ports:
     </p>
+    <ul>
+      <li>One uses the ZiLOG ez80f0910200kitg development kit, and

-      <b>STATUS:</b>
-      Kevin Franzen has integrated and verified the ez80Acclaim! port and he has
-      graciously provided the changes that he made.  So I do not have first hand
-      experience, but the ez80Acclaim! port should be functional.
-      Kevin's changes were released in NuttX version 0.4.2.
+      Both boards are based on the eZ80F091 part and both use the Zilog ZDS-II
+      Windows command line tools.
+      The development environment is Cygwin under WinXP.
     </p>
     <p>
-      The EMAC driver has not yet been verified.
+      <b>STATUS:</b>
+      Testing with the ZiLOG ez80f0910200kitg has been performed only on the on the ZDS-II simulator.
+      However, support with the  ZiLOG ez80f0910200zcog-d is complete.
+      The first integrated version was released in NuttX version 0.4.2.
+      As of this writing, that port provides basic board support with a serial console.
+      An eZ80F09 EMAC driver has been developed, but not fully tested as of that releas.
