Quadra 840av

Matt,

Sorry to say, you will need to get a monitor. The Apple IIGS will output the primary signal to the RCA jack but not so on the 840AV. Apple Video Player will output a signal to the AV jacks but you need the primary monitor to run AVP.

As for using the powerbook as a monitor, that also is backwards. The PB will act as a hard drive to the 840 AV but not a monitor.

Use the composite video output, and hold down Command Option T V at startup until the second chime:

"The Macintosh Quadra 840 AV and Macintosh Centris 660 AV video driver lets the user connect a television set as the computer’s sole display. This is done by the PrimaryInit code; if there is no monitor connected to the DB-15 port, the code checks a bit in its slot PRAM to determine whether the user has enabled the boot-on-television feature. If the bit is set, the video driver opens and the monitor output is displayed on television equipment connected to the composite output ports. The Options dialog box of the Monitors control panel provides a checkbox to allow the user to select this feature.

Video Driver

Monitor output is directed to the video output connector in television format only if there is no monitor connected to the DB-15 connector. If the user has not clicked the checkbox in the Options dialog box of the Monitors control panel, this feature can also be enabled by holding down the Command-Option-T-V keys during startup. If this is done, the machine will boot up, play the boot beep, and replay the boot beep a short time later. At that moment the user can release the keys and the computer will continue the startup process, using the connected television set as its main display."

Grant,

Thanx. I love to be proven wrong because it means I am learning something new! Now how about developer notes for the 7100 and 8100s? While we are at it, what about the personality card for the 8500, 9600 and G3? : )

Quizzical Floppy has been responsible for more (metaphorical) spillage of ink in this part of the Discussions than almost any other cause. Lack of a valid System Folder from which to boot, and that is what QF signifies, is fundamentally crippling for any Mac. You will find the causes and cure of Quizzical Floppy well rehearsed in this collection of posts.

You have posted a perfect thread about that matter on June 17.05 which I copied.Can't get the URL anymore. Would you allow to copy this here to get it in the list again?

I think AppleIIFreak was asking someone to:

1) Find Denis Eddy's posting of 17 June 2005
2) Copy the text.
3) Paste it into a new reply below.

Sorry-asked Denis Eddy for permission to copy(ToU,Copyright)-URL is unavailable since change in November.

I dont have a moniter that works with it

If that is because of the non-VGA Apple video connector (and you have a regular VGA monitor), you should be able to easily convert it to a standard VGA port with an inexpensive adapter. The type that has worked well for me looks like this one on eBay.

I don't know about this vendor; the ones I bought from eBay look like these yellow ones. I don't have an 840AV, but it works perfectly on the AV video out connector of a Power Mac 8100AV. And these are much easier to use than the adapters with the dip switches and dials.
