+      <para>FujiNet adds a complete Z80 computer emulation that runs a copy of
+      RunCPM. This provides complete <trademark
+      class="registered">CP/M</trademark> 2.2 compatibility, being able to run
+      thousands of additional programs, such as <trademark
+      class="registered">WordStar</trademark> and <trademark
+      class="registered">dBASE II</trademark>.</para>
+
+      <para>To make this easier for most users, CP/M files are stored directly
+      on the SD card, without needing to deal with floppy disk image formats.
+      Any CP/M program or data file in question can be copied to your local SD
+      card, placed inside the CPM/ folder, and used.<figure>

+
+      <para>The CP/M emulation uses the SWP ATR8000 protocol for connecting
+      the CP/M computer to the Atari. This means that programs such as DT-80
+      can be used to provide the requisite terminal program. In addition, the
+      CP/M emulation can be accessed by any Atari MODEM program that supports
+      the "R:" device.</para>

+      <para>Because the micro controller provides an 8-bit

+      provides an AUDIO IN pin, it was trivial to add an implementation of
+      Don't Ask Software's Software Automatic Mouth (S.A.M.) directly on the
+      FujiNet device! This has the advantage of not blanking out the display
+      when you wish to use the voice synthesizer. </para>
