                                HARD DRIVE

There are a number of ways to install hard drives.  You can install hard
drive(s) in the 3.5" or 5.25" drive bays which is very straight-forward.
I chose to purchase the optional hard drive "piggyback" board which allows
you to install a hard drive on the G-Force itself. You can also install a
hard drive on a separate host adapter if desired.

In most cases, you will get the best performance from the on-board SCSI
host adapter.  However, you may want to use a controller such as the
Oktagon 2008 that has even better performance, or a non-DMA adapter that
doesn't interfere as much with the serial port.

It is not necessary to install a hard drive and the SCSI host adapter can
be disabled with a jumper in such cases.

                              PIGGYBACK BOARD

The G-Force piggyback board sells for about $40.  It's a sheet of aluminum
with metal bolted to the sides to hold a 1" hard drive in place.  It sits
very close to the G-Force and can act as a heat sink to the hard drive.
I've never had any problems with it overheating the G-Force.  There is
about 0.5cm between it and the G-Force which seems to let enough air though
to keep the G-Force from getting too hot.  It mounts to the G-Force with a
screw, two clips (part of the folded aluminum) and a piece of metal that
hugs the G-Force on top.  It works out to be a solid installation and I
can't forsee any problems with it falling apart.  I felt it was a very
valuable addition to the G-Force and would recommend that it be purchased
along with the accelerator if you have or are buying a 1" high hard drive
to complement the G-Force.  The price seems steep for such a product, but
considering its functionality, it's worth it.

                               RAM EXPANSION

Soon after buying the standard model with 4MB of 32-bit RAM, I realized it
wouldn't be enough for my needs.  I purchased a 64-pin GVP 4MB SIMM for
$210 at a local dealer.  It came in an unusually large box (23 x 15 x 4.5cm)
and was wrapped in a thick, pink anti-static plastic bag.  It snapped into
the SIMM socket and held firmly without any adjustments.  The RAM was
detected and used with no need for special "addmem" utilities in the
Startup-Sequence.  This allows more of the operating system to load into
the faster 32-bit RAM than with an addmem utility.  Unlike some SIMM
sockets, it's very easy to remove these SIMMs without special extracting
tools and they seem strong - unlike the sockets on some other products.

                              G-FORCE 040/33

Before actually installing the card, you need to make some decisions.  You
need to tell the card what type of SIMM(s) are installed, whether you want
the parallel port to be IBM or Amiga compatible (among other small changes,
Amiga compatible mode puts 5V on pin 14, used by some sound samplers and
video digitizers), and whether you want burst mode or not.  Burst mode
requires that all SIMM sockets be filled with 4 or 16MB SIMMs.

Installing the card is somewhat difficult.  The case of the A2000
interferes with the serial and parallel ports on the rear of the G-Force.
A slip of paper that came with the G-Force suggests that you remove the
plastic guide in the front of the A2000.  If that isn't enough, remove
remove the screws from the power supply to allow the case to bend slightly.
The idea of having the most expensive card in my system not secured in the
front did not please me.  I chose to unscrew the power supply and all the
cards in my system to allow the case to bend enough for the G-Force to fit.
It worked and did not cause any damage to the case.  You must be VERY
careful not to allow the G-Force to bend.  If you allow the case to "snap
back" while installing the G-Force, you might break your accelerator!

After installing the card itself and securing it by two screws, you must
choose whether or not you want the Mac compatible DB25 external SCSI
connector.  If you decide to use it, you may install it in the second open
position next to the CPU plate, or in an unused bracket (Zorro II)
position.  A plate and bracket are provided.  I put it in the position next
to the CPU plate (where a MIDI interface normally goes) and installation
was next to effortless.

Some of you may be the type to "shoot first and read the manual later." DO
NOT DO THIS WITH THE G-FORCE.  There are a number of points you should be
aware of when installing this board including a number of "user-decisions"
that must be made prior to installation.


Installing the software was painless.  The installation took advantage of
Commodore's "Installer" software and put hard disk prepping utilities, a
patch to make using the internal serial port more reliable at high speeds,
a "ShowConfig" type of utility, utilities for controlling the serial and
parallel port, 68040.library 37.30, and setpatch 40.16.  The installer
automatically put a command to remap the Kickstart to 32-bit RAM in the
