INFOCOM Interpreter patch
-------------------------

Interpreters for INFOCOM's text adventures exist for many
platforms including CP/M-86.  While a CP/M-86 interpreter
for the DEC Rainbow 100 is commonly available none has yet
been located for IBM-PC CP/M-86, and unfortunately the DEC
version does not work on the IBM-PC.

IFCPAT is an MS-DOS program that patches the DEC Rainbow 
interpreter version A so that it will function correctly
under IBM-PC CP/M-86.


Make a copy of your DEC Rainbow interpreter (e.g. ZORK1.CMD)
and rename it to INFOCOM.CMD.  Place IFCPAT.COM in the same
directory and run it.  That's it.


Use of this program is at your own risk and responsibility.
