FORWARD
You have just purchased another high quality product of ICD, Inc.
We are the company which brought out exciting products for your
Atari like: SpartaDOS Construction Set, US Doubler, R-Time 8,
and P:R: Connection. For more information on ICD products, be
sure to fill out and send in your warranty registration card in the
back of this manual.
The installation section of this manual includes three graphic
layouts for trouble free installation. The technical description
shows the complete addressing scheme used with RAMBO XL. Our
motto is "exceptional value at a reasonable price." You will see
this carry through with our new RAMBO XL. We would like to thank
Claus Buchholz and Ron Boling for inspiring the development of
RAM upgrades for the XL computers.
CAUTION: This is a very high quality product which, if properly
installed, will enhance your computer's function. However, RAMBO
XL must be installed internally and takes a certain degree of skill.
A careful novice with soldering skills can install this product
without any outside help as long as directions are followed and the
ICs are all socketed. If you do attempt to install this yourself and
do some damage, ICD will repair your computer and install RAMBO
XL for you. However, don't be upset if you are charged a service
fee (to repair damage) on top of our installation charge.

This manual is supplied as part of the RAMBO XL package from
ICD, Inc. The divisions of the manual and their contents are as
follows:

Chapter 1-Introduction to RAMBO XL
CHAPTER 1-INTRODUCTION TO RAMBO XL
RAMBO XL Compatibility
RAMBO XL will work in any Atari 800XL or 1200XL computer
regardless of which ANTIC chip is used. The 1200XL will require
four jumper wires to be soldered along with soldering of the ribbon
cable. The 800XL will require one or two jumper wires to be
soldered along with soldering of the ribbon cable. Additionally,
some 800XL computers have integrated circuits (ICs) soldered
directly to the printed circuit board (PCB). If that is the case, we
strongly recommend you send your computer to ICD for
professional installation.
Compatibility With the 130XE
RAMBO XL makes your 800XL or 1200XL compatible with the
130XE in the CPU mode for extended memory. This means that it
will work with programs like BASIC XE from OSS and also support
the Ramdisk version of Atari DOS 2.5. Although RAMBO XL
actually gives you 256K of memory, the 6502 micro-processor can
only address 64K at one time. To add memory and get around this
limitation, bank selecting is used. This method used by both the
130XE and RAMBO XL uses a 16K window from $4000 to $7FFF in
the computer's memory map. These banks are controlled by the
unused ports of the 6520 PIA. The 130XE switches its four 16K
blocks of memory, one set at a time, through this window. RAMBO
XL switches twelve 16K blocks with the last four being addressed
the same as the 130XE. (See technical notes for programming
information).
RAMBO XL is compatible with the 130XE in the CPU mode, not the
ANTIC mode. The ANTIC mode allows the display to remain
undisturbed even if the display memory falls into the $4000-$7FFF
range and the banks are changed. If this happens with RAMBO XL
installed, the display will flicker as banks are changed. The program
will still operate properly except for the annoying
flickering of the screen. This display flickering can be prevented by
keeping your display list out of $4000-$7FFF.

Chapter 1-Introduction to RAMBO XL
RAMBO XL has been tested to be fully compatible with
the following programs:
BASIC XE from OSS ...................... same as 130XE
Synfile+ from Synapse ................... same as 130XE
Atari DOS 2.5 RAMDISK ................... same as 130XE
PaperClip from Batteries Included ..... same as 130XE or with
optional configuration it uses the full memory.
RAMBO XL uses 256K DRAMS for the computer's main memory
and bank memory. These "state-of-the-art" memory chips retain
their memory much longer than the old 64K DRAMS used by
Atari.
The one disadvantage of this longer memory retention is that you
must wait a few seconds after turning your computer off before
you turn it back on. If you don't, the computer may lock up (crash)
when powered on.

Chapter 2-Pre-Installation
CHAPTER 2-PRE-INSTALLATION
BEFORE YOU START
Tools
This installation is not for the total novice. The tools needed are:
#1 and #2 phillips head screwdrivers
20-35 watt soldering iron (fine point)
small gauge rosin core solder
small needle nose pliers
small diagonal side cutters
small flat bladed screwdriver
solder sucker (if ICs are soldered in)
matches or a cigarette lighter
small dish for parts
Parts supplied
The following parts should be included with your RAMBO XL
package:
1 RAMBO XL piggyback board
3 Jumper Plugs (plugged onto RAMBO XL)
1 piece of fine hook up wire (for jumpers)
1 piece of heat shrink tubing
1 installation manual
8 256K DRAMS (optional)
PRE-INSTALLATION NOTES
Purchase your 256K DRAMS
If you have not purchased the RAM chips with RAMBO XL, then
you should purchase eight high quality 256K dynamic RAM chips
before beginning this installation. These are available either from
ICD, your dealer, or the suppliers listed at the end of this
manual.
We could have included the RAM chips in this kit but that would
have artificially inflated the price of RAMBO XL. RAM prices
change faster than computer prices. Nobody wants to be caught
holding a large inventory when the price drops.

Chapter 2-Pre-Installation
Check for Sockets
A few things must be determined before installing RAMBO XL.
First you must determine whether the integrated circuits (ICs or
chips) in your computer are in sockets or soldered directly to the
printed circuit board (PCB). Most 1200XLs should have sockets on
all ICs. On the other hand, many 800XLs have some or all ICs
soldered directly to the PCB. If this is the case, we strongly
recommend you have an expert install this product. If all ICs are
soldered to the PCB then you will have to unsolder nine 16 pin ICs.
That is difficult for even the most skilled technician.
If you have problems or change your mind, ICD will provide
complete installation of your RAMBO XL for $30.00 including
shipping one way. If your computer needs repair, our service
charge is $45.00 plus parts. This price also includes shipping one
way.
