+MEMSHIFT.UNP
+============
+
+
+In the spirit of a recent patch to unprotect LOTUS 1-2-3, I discovered
+the same logic can be applied to unprotect MEMORY/SHIFT.
+
+1. Rename MS.EXE MS.XYZ
+2. DEBUG MS.XYZ
+3. type  U 1565
+4. you should see    INT 21   at that address
+5. type  E 1565 90 90
+   type  E 1567 90 90
+6. type  W
+7. type  Q
+8. Rename MS.XYZ MS.EXE
+
+Finally, make sure command.com resides on the disk where MEMORY/
+SHIFT  is initiated.
