+OS2CCP & OS3BDOS
+----------------
+
+Sourced from DRIPAK archive.
+
+It appears to have come from DRI and seems to be the closest
+version of pure original source.  The source is commented, but
+utilizes multiple statements per line.

+
+CCP & BDOS
+----------
+
+Sourced from DRIPAK archive.
+
+It is a nicer formatted version of above.  Lines
+expanded to one statement per line.  The case of message string
+literals has been modified, but
+otherwise byte identical to OS2CCP & OS3BDOS.

+
+CCP22 & BDOS22
+--------------
+
+Sourced from DRIPAK archive.
+
+It is an independent disassembly and reconstruction of CCP/BDOS.
+DRI CPM22PAT01 was already applied.  Unclear why, but the BDOS
+source was checking for a blank instead of a ctrl-s in the
+KBSTAT routine.  Ctrl-s seems to be correct based on all other
+BDOS images I have encountered.  Also, these files imbed the
+CP/M version number into the serial number fields.  Other than
+this, they are byte identical to the OS2CCP/OS3BDOS images above.

+
+CCPB03 & BDOSB01
+----------------
+
+Sourced from N8VEM effort to create an enhanced
+variant of CP/M 2.2.
+
+It appears to be a disassembly and reconstruction of CCP/BDOS,
+but there are no comments attributing the work.  DRI CPM22PAT01
+was already applied.  The message string literals are all
+in CAPS in BDOS.  Additionally, there is explicit filler of 0x55
+value bytes at the end of the CCP/BDOS files padding their
+length out to full page.  Other than this, the BDOS
+is byte identical to the others above.  CCP contains multiple
+enhancements and is, therefore, not identical to others.
+
+CCPB03.ASM - Enhanced reassembly of CCP
+
+BDOSB01.ASM - Reassembly of BDOS w/ DRI Patch 01
+
+---
+
+The first 6 bytes of BDOS are the serial number.  In general,
+the BDOS sources just leave all six bytes as 0x00.  The
+one exception is BDOS22 which defines the 6 bytes to be a
+hybrid of CP/M version information and serial number.  This is
+basically irrelevant unless MOVCPM is used, in which case
+the 6 byte serial number field must match with MOVCPM.
+
+---
+
+The DRI CP/M Patch #01 (DRI CPM22PAT01) is defined to be
+nop; nop; lxi h,0 and that is how I have patched OS3BDOS & BDOS.
+However, BDOS22 uses nop; nop; lxi h,fbase for the patch.
+In practice, this difference does not matter because the value
+placed in HL at this point is unused (immediately overwritten).
