+pjrc-8051 README
+^^^^^^^^^^^^^^^^
+
+This port uses the PJRC 87C52 development system and the SDCC toolchain.
+
+The PJRC 87C52 development system can be obtained from http://www.pjrc.com/.
+
+The SDCC toolchain is available from http://sdcc.sourceforge.net/.  All
+testing has been performed using verison 2.6.0 of the SDDC toolchain.
+
+Building the SDCC toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The SDCC toolchain is built with the standard configure/make/make install
+sequence.  However, some special actions are required to generate libraries
+compatible with this build.  First start with the usual steps
+
+  download
+  unpack
+  cd sdcc
+  ./configure
+  make
+
+But before installing, we need to apply a patch to the SDCC 2.6.0 source.
+WARNING:  This patch is specific to the particular combination of CFLAGS
+that are used in the compilation.  If you change Make.defs, then you will
+likely have to change the patch as well.
+
+  Apply sdcc-2.6.0.patch
+  cd sdcc/device/lib
+  make model-mcs51-stack-auto
+
+Then
+
+  cd sdcc
+  make install
+
