+    <p>Emu48+ is a modified version of Emu48 to add support for the ARM-based 
+    calculators.  It does not emulate the ARM CPU, but it enhances the 
+    Saturn emulation to more closely match the emulation provided by the 
+    Saturn emulator on the ARM-based calculators.</p>
+    <p>Emu48+ adds support for many of the Saturn+ instructions, including 
+    some of the BUSCC instructions, and it also adds support for the 80-line 
+    display used on the 49g+ and 50g.</p>
+    <p>At present, the additional calculators supported in Emu48+ are the 
+    49g+, 48gII (hardware revision 1), 50g, and 39g+/39gs/40gs.</p>
+    <p>To create KML scripts for the additional calculator models, use the 
+    following model codes:</p>
