Yes, the following document is written and copyright by IMS and includes useful information about the Twin Turbo 128M card.
Why upon initialization is there an icon with a red X across it?
---------------------------------------------------------------
This simply means that the TwinTurbo accelerator is loaded in System Folder Extensions and an accelerator that was previously loaded is no longer being used. To prevent this from happening go into System Folder Extensions and put the icon (the one that comes up with the red x on initialization) into a separate folder.
In which Power Macintosh systems and compatibles does the TwinTurbo-128M work?
------------------------------------------------------------------------------
The TwinTurbo-128M works in all the PCI based Power Macintosh systems, such as the 9500, 8500, 7500, 7600 and 7200. The TwinTurbo-128M also works in the Macintosh Compatible systems such as Supermac S900, Power Computing PCI based Power Wave, Power Center and Power Tower systems, and the Daystar Genesis MP.
Will the TwinTurbo-128M work in a system with Nubus slots?
----------------------------------------------------------
No, the TwinTurbo-128M will only work in PCI based Macintosh and Power Computing systems.
Does the TwinTurbo-128M have to go into a particular PCI slot before it will operate?
-------------------------------------------------------------------------------------
No, the TwinTurbo-128M will work in any PCI slot in any of the above mentioned systems. NOTE: In the 9500/132 it is recommended that the TwinTurbo card be placed into one of the bottom three slots.
What software comes with the TwinTurbo-128M?
--------------------------------------------
TwinTurbo Accelerator and TwinTurbo Control Panel. The latest driver can be obtained from our Web Page (at
http://www.integratedmicro.com/download.htm) or you may call IMS technical support and they will be glad to mail the accelerator disk to you.
What special features does the TwinTurbo Control panel have?
------------------------------------------------------------
Capability to Pan/Zoom, change resolution on-the-fly, disable accelerator by typing in a simple key stroke command and support for Synch on Green monitors.
What resolutions will the monitor support?
------------------------------------------
The TwinTurbo will support up to 1920x1080 in thousands of Colors and 1152x870 in millions of colors.
Do I have to do anything special to see 1920x1080 or 100hz?
-----------------------------------------------------------
Simply go into the TwinTurbo Control Panel, hold down the Option key on the keyboard and click the Resolution button.
What would prevent me from not seeing all of the resolutions?
--------------------------------------------------------------
There are two things that can cause this. One is if your monitor is a non-multisync monitor. If this is the case you will need a sense-code adapter to see all the resolutions. The second reason is if your monitor is a fixed-frequency monitor. There is no solution for this type of monitor.
Why are there two different types of inputs on the back of the TwinTurbo?
-------------------------------------------------------------------------
The TwinTurbo can support both VGA type and Macintosh monitors.
Can one TwinTurbo-128M operate two monitors?
--------------------------------------------
No. But you can put two TwinTurbo's in one system and run one monitor off of each card.
What if I want to operate two monitors but do not want the second monitor to run off of the Twin Turbo-128M?
--------------------------------------------------------------
The TwinTurbo-128M will work in the same system with another graphics accelerator card.
Upon initialization the screen 'flashes', what causes this?
-----------------------------------------------------------
When our accelerator is loaded it attempts to re-synch the monitor for the best resolution and frequency.
Whose video accelerator chip is being used in the TwinTurbo-128M?
------------------------------------------------------------------
The video accelerator chip on the TwinTurbo 128M was designed by our own engineers.
When I shut down my Macintosh and power on the system again the 640x480 resolution comes up even though I selected the 1024x768 resolution previous to shutting down. How do I make the system come up in the resolution I last left it?
-------------------------------------------------------------------
Anytime you install a new graphics accelerator card or install your graphics accelerator card into another PCI slot in your Macintosh system you must first open up the systems monitor or sound and display control panel to allow the Macintosh system to properly recognize the new addition to your computer. This only has to be done for new installations or if you've moved the card to another slot.
When the TwinTurbo-128M card is plugged my Apple 1710AV monitor the screen comes up with a greenish cast. Why?
----------------------------------------------------------------------
The TwinTurbo card is set to have a feature called Synch on Green enabled, since the Apple 1710AV monitor does not require this feature you must disable the Synch on Green jumper on the TwinTurbo card. To do this change jumper JP4 from position 2-3 to position 1-2. (Editor's Note: The 4MB IMS card (tt128m) has the jumper. The 8MB card (tt128m8) does not.)
