- PRODUCT NAME
-
- DP IBM Analog Joystick Interface
-
-
- BRIEF DESCRIPTION
-
- The DP Interface is a hardware converter that allows the use of
- analog joysticks on the Amiga, for programs that recognize standard IBM
- analog joysticks.

- SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
-
- HARDWARE
-
- Requires an IBM compatible analog joystick.
-
- SOFTWARE
-
- None.
-
-
- COPY PROTECTION
-
- None.
-
-
- MACHINE USED FOR TESTING
-
- Amiga 2500, 25 MHz 68030/68552/68882
- 2 MB Chip RAM, 10 MB Fast RAM
- Kickstart version 37.300, Workbench version 38.35
- Advanced Gravis Analog Joystick
-
- INSTALLATION
-
- Extremely easy. All you need to do is plug the joystick into the
- DB-15 end of the interface, and then plug the 9-pin end of the interface
- into port 2 (joystick port) on the Amiga.

- REVIEW
-
- While playing my favorite flight simulators, I noticed that there
- was a performance barrier caused by the software. After many phone calls,
- and some personal research, I came to the conclusion that it was a hardware
- restriction, and decided to pursue getting an analog joystick for my Amiga.
- Looking for analog joysticks for the Amiga is like trying to find hard
- drives for the Commodore 64: possible, but not likely. Enter the DP IBM
- Analog Interface.
-
- With an analog joystick, you can experience the realism built into
- the software which is unavailable to digital joystick users due to the lack
- of sufficient input parameters. Using an analog stick requires a new
- mindset about programs that support them. For example, you can align the
- joystick manually for best performance (see next paragraph). Once properly
- aligned, the analog joystick gives a sense of feel and control that more
- accurately mirrors the actual response to a real joystick in a real plane,
- at least as far as the program is concerned. I tried the analog versions of
- several games, and found some amazing differences, as well as some astounding
- conundrums.
-
- To align the joystick, you first set a 3-position impedance-matching
- slide switch, which allows for rough calibration. Next, you trim the pots
- on the X and Y axis yokes with a nonconducting miniscrewdriver until you are
- either straight and level, or the setup program shows you zeroed for stick
- center.
-
- Below is a tabulation of my results with a few programs supporting
- the analog joysticks.
-
- Fighter Duel Pro Flight Recorder
- Works well in all switch positions, and the stick recenters
- accurately, although there is no provision for calibration or
- feedback.
-
- A-10 Tank Killer (Version 1.5)
- This was the second most consistent and stable program tested.
- The preferences menu has joystick analog/digital and calibrate
- joystick, and it works well. This is by far the most elegant and
- straightforward implementation yet tested. This program MUST
- be run from a hard drive with an accelerated machine, and/or
- with analog joystick mode selected. I chose graphic mode 5 -- full
- 64-color with autodither -- and found the frame rate acceptably
- smooth and accurate. Stock machines running the 68000 CPU at
- 7.14 MHz wouldn't be able to control the game, even at graphics
- level 1. I know: I tried and found it unacceptable.
-
- Flight of the Intruder
- This rather lame flight simulator has a first-rate analog joystick
- calibration program, enabling you to accurately set the proper
- switch position on the interface, and the trim pots as well.
-
- Knights of the Sky ("KOTS")
- This great flight simulator is hampered by the fact that to use the
- analog joystick feature, you must disable any accelerator or
- advanced processor that is present. This was with the CBM A2630
- with 4 MB of RAM, and a DKB 2632 with 4 MB RAM. This is rather
- odd, as DP is the official interface of MicroProse, and MP is
- known for producing excellent and well-behaved programs. I don't
- know what the problem is, but both DP and MP said that some
- accelerators don't work well with this combination. Oh well.
-
- F-15 Strike Eagle II
- Same as with KOTS, except the accelerator made the program hang.
- Sound kept on going, but the graphics just froze. So no
- acceleration for those wanting to use MP games with analog
- joysticks. Seems like this could be remedied by MP, IMHO.
-
- Birds of Prey
- While no specific commands, menus, or keyboard hotkeys activate
- the analog joystick, the game does appear to autosense the input
- device, and auto-center as well. While handling is greatly
- improved, targeting and landing are significantly more difficult.
-
- After you are done experimenting with settings for a particular
- program, I recommend creating a README file to remind you of the best
- settings to use, as I have.
-
-
- DOCUMENTATION
-
- The instructions come on a 5x7 inch, single-sided sheet that is
- pretty straightforward. There is even a recommended list of sticks which
- includes all but the Kraft Thunderstick and the Thrustmaster, since they
- require a special card inserted in an IBM 8 bit slot. I doubt if these two
- sticks would work on the Amiga side of a Bridge Board setup, although I've
- not tested this idea.
-
- LIKES AND DISLIKES
-
- I like the basic product, and wish it had support for the use of
- rudder pedals. Rudder pedal support comes from their DP IBM Bus Mouse
- Interface, which also allows the use of 400 DPI mice. What I'd like to see
- is a product which incorporates both of these devices. The bus mouse
- interface retails for $9.95 US, and an order form comes with the DP joystick
- interface.
-
- I also like the support staff; see VENDOR SUPPORT, below.
-
- You won't be disappointed with this product, and upgrades are
- promised in the future to support the CH Flightstick with the "Coolie Hat,"
- but no time frames have been given.
-
-
- COMPARISON TO OTHER SIMILAR PRODUCTS
-
- The only other competition is the Amiga Smart Port from IDD. For
- almost four times the price, it allows the use of rudder pedals, and the
- coolie hatted CH Flightstick. For the money, you just can't beat the
- combination of mouse and joystick interface for full analog joystick, and
- rudder pedal use.
-
- BUGS
-
- NONE
-
-
- VENDOR SUPPORT
-
- The support staff are all Amiga, and are very loyal to their users.
- They are very enthusiastic, receptive, and knowledgeable. As they are now
- the official MicroProse analog interface, I am hoping for better support of
- those users running faster machines than a box stock A500. What with
- A3000's and A1200/4000's out in greater numbers, it seems a rather sad
- commentary on the state of Amiga software vendor support when they go for
- commonality rather than excellence, as is found in the IBM world.
-
- The vendor asks for ideas, and will share some of its profits with
- anyone whose ideas that they adopt into production. This is my kind of
- company!
-
-
- WARRANTY
-
- 90 days on parts and labor, from date of purchase.
-
-
- CONCLUSIONS
-
- This is a great product for the money, with lasting value and
- usability. I would urge all flight simulator fans strongly to consider the
- DP interface, just to see the amazing difference it will make in your playing
- enjoyment. While I haven't tested the IDD interface for comparison, I feel
- that for the money you won't find anything better anywhere, AFAIK.
