The following 4 postings contain everything needed to turn an 
Apple ][, ][+, //e, //c into a vt100 emulator.  (As of this posting,
I'm not sure if it will run on the //gs, but the "Tech notes" I've
seen from Apple seem to indicate that it will.  Any volunteers?)

DCOM Version 3.3 differs from 3.21A and 3.2 due to added/improved code
for faster emulation, printer support and more "features".

The phrase "new and improved" comes to mind.

To get the program to run, you will need to download the three text
files that comprise the emulator.  To do this, strip of the news header
off each posting and use your favorite file transfer program to download
them to your apple.  These files are actually 15 or so files "packed"
into 3.  To unpack them, you use the DOS 3.3 command 'EXEC' that reads
each file and pretends that you typed it from the keyboard.  So,
basically, each file is a sequence of program lines followed by BSAVE's
which will automatically save the files for you.  This makes unpacking
(usually) painless.

Start with a FORMATTED BLANK diskette. Download the three files for
the apple (call them APPLE1, APPLE2, APPLE3) and type:

----------------
]EXEC APPLE1
{CHURN CHURN}

PART ONE UNPACKED...

]EXEC APPLE2
{CHURN CHURN}

PART TWO UNPACKED...

]EXEC APPLE3
UNPACKING FINISHED... BOOT ME.
----------------

WARNING!
	When you download the files, they will most likely have bit
	8 (the infamous high-bit) cleared.  DOS really would like to
	see this bit set.  I'm not sure of a good method, but people
	have reported that ASCII express's editor will do this.

Each stage of unpacking will be displayed on the screen and a row of
asterisks and square brackets will stream down the left side of the
screen so you know that it's actually doing something.  Each of the
three unpacking sequences will announce that they are complete.  At
the end of the third file, you will be requested to boot the disk.
Do so, and the emulator will start up.

The instructions are pretty much complete so I won't repeat them
here, they will appear in the next posting.

If you have problems downloading the Apple files, I'll send you a
diskette with the emulator binaries if you do the following:

	1) Mail me money ($8.00) 
	2) Mail me a diskette/mailer/return postage

It is a shareware program and I request $25 if you use it, or $35
if you want the source code.

If you send me $8.00, that can be deducted from the $25 donation if you
decide to donate.  Otherwise, your initial risk is minimal.

So, whatever your choice, mail it to:

	Jim Hayes
	P.O. Box 221044
	University City, CA
		92122-1044

E-Mail any questions, gripes, etc. to the E-mail address BELOW and not to
the account that posted this.

ENJOY!
