Quadra 700 teardown photos


Recommended Posts

Nice, and a Hebrew keyboard again.

Is this LCD screen connected to your Quadra 700? With the built-in graphics card? And if so, what resolution is the screen? 19"?

What kind of resolution do you get from it? Isn't it either 800x600 or 1152x870? It doesn't look like either of those.

 

Edit: Sorry, I didn't see the picture said it's a 650. I only saw you used the same keyboard. But still, what kind of resolution do you get from the Quadra 700 on a VGA monitor (with adapter)?

Hi,

 

Nice, and a Hebrew keyboard again.

Is this LCD screen connected to your Quadra 700? With the built-in graphics card? And if so, what resolution is the screen? 19"?

What kind of resolution do you get from it? Isn't it either 800x600 or 1152x870? It doesn't look like either of those.

 

That's a 24" Samsung monitor, and both the Q650 and the Q700 give 1152x870 when connected to it. The adapter has switches which are supposed to change the resolution, but I get the same results whatever configuration I use. I don't really understand how this is supposed to work.

 

I really want to max out the video memory of both Quadras, because they are both limited to 16 colors at that resolution.

but can it do 1024x768 on a (15") LCD screen? I read somewhere it can't, just the two resolutions I mentioned?

Even though 1024x768 is less than 1152x870.

 

Sorry to revive such an old thread, but I wanted to add this in here for anyone else looking for the same answer. According to http://archive.retro.co.za/mirrors/68000/www.vintagemacworld.com/radius/smacdisp.html:

Q: Why don't I get any picture when I hook up my 20" SuperMatch display to the built-in video of my Quadra 700? I'm using the 1024x768 cable adapter, but it doesn't help.

A: The Quadra 700 & 900 lack the proper oscillator and cannot support the normal 19" or 20" mode of 1024x768 resolution. The only solution to use this resolution with these Macs is to install a graphics card.

 

Here's more evidence of the Quadra 700 not supporting 1024x768, from Apple (https://support.apple.com/kb/SP235?locale=en_US):

Resolution Video Memory
512K VRAM


(built in)
Video Memory
1MB VRAM
(2x256K)
Video Memory
2MB VRAM
(6x256K)
512 x 384 8-bit 24-bit 24-bit
640 x 400 n/a-bit n/a-bit n/a-bit
640 x 480 8-bit 8-bit 24-bit
800 x 600 n/a-bit n/a-bit n/a-bit
832 x 624 8-bit 8-bit 24-bit
1024 x 768 n/a-bit n/a-bit n/a-bit
1152 x 870 4-bit 8-bit 8-bit
1280 x 1024 n/a-bit n/a-bit n/a-bit


Notes: 512K VRAM SIMMs may be installed, but only 256K of each SIMM will be used.

 

So it looks like the onboard video doesn't have the necessary oscillator to create the proper VGA timings of 1024x768. I guess I'm looking for a NuBus video card for my Quadra 700 now :O

FWIW, 1024x768 was added for the Quadra 950 speedbump (16-bit with 2MB.) Little disappointed there wasn't also a 750, but I suppose the 650 filled that gap the following year.
