Installing the Latest Library
-----------------------------

To install this new Library software into S4, a new Library ROM needs to
be created.  This procedure is described below:

1. Download HEXE300.HEX to S4 in the normal way.  HEXE300.HEX is an
Intel Hex file.  The data will reside between addresses 08000-0FFFFH.

2. Do a RAM checksum (Grey SUM key) from 08000 to 0FFFF:

>CHECKSUM RAM
08000,0FFFF

The resulting SUM should be: 002A0801

3. BURN a (blank) 27256 from 08000-0FFFFH:

>BURN
AMD 27C256
12.75V Burn pin 1
 08000-0FFFF=00000

4. Do a ROM checksum (Green SUM key).  The SUM should be the same as the
RAM checksum above.

5. With the freshly Burnt Library ROM in S4's ZIF socket, press LIB, and
then ENTER.  The Library program will now load, and S4 should the
display the following sign-on message:

DATAMAN S4 LIB 
LIB 3.00
XXXK BYTES RAM
>

"But my S4 has lost it's Library, I can't BURN a 27256"
-------------------------------------------------------

No problem.  When S4 has no Library loaded, it is possible to program a
27256 at 12.5V, using a 500us pulse width.  This is suitable for most,
but not all 27256 EPROMs.  If you do program a 27256 with no Library
loaded, MOVE the Library code down to address 00000 before BURNing:

>MOVE 08000,0FFFF,00000

If you don't fancy actually BURNing an EPROM at all, there is another
way to install a Library into S4. S4 has the facility to load directly 
from the serial port into its library memory, using the S4 driver for
Windows and the Receive Library function.

If you require further help on re-loading the Library, please contact
