Hmm...

In all my lookins' on the Internets, I have never encountered a dual-head (dual-monitor) nubus or PDS video card. I suppose one just added another video card in order to get 2+ monitors back then.

Never seen dual monitor ones

But I HAVE seen one that had composite out. I believe it was a Video editing one that had it's own HardWare MPEG-1 En/De-decoder. I believe the Composite was used with a special video editing app that used a plugin that would cause it to output the video to composite. but it wasn't a mirror, and it wasn't spanning. More of an outlet of only the video you were editing so you can see what it looks like when it will be on a TV. IIRC, the card cost like $20k and I haven't been able to find one since.

I don't recall who made it, but my aunt used it with a Quadra 950 in her "Gourmet Images" Video editing business. I was hoping to get the system about 7 years ago, but I think she threw it out. Shame, I never got to play with it Sad

Back then, i believe from looking at the box, it was a full length Cards, and it had 6MB VRAM. Was an amazing thing when I saw it in action. Never was able to catch the name of it. But I was drooling at the specs of it.

They say Lopis but I'm almost

They say Lopis but I'm almost certain they meant Lapis. It'd be nice if they posted the model number.

Faux Dual Head PDS Card

I've never seen a dual head NuBus card, although the link in another posting makes it look like there was one.

In the case of PDS cards, there is one card which may appear to be dual head and it is not. When Power Computing made their first clones, they modified the Power Mac 8100. In their versions (Power 80, Power 100, Power 120) they included a PDS Video card which had both a VGA port and a standard Mac DB15 video port. However, despite the presence of two connectors, the Power Computing PDS card is not dual headed. One port or the other can be used, depending on the setting of a switch on the video card.

It's been so long since Power Computing did its thing, that their PDS video card might be found in any of the x100 machines--folks have had plenty of time to move the cards and forget their origins.

Re: Faux Dual Head PDS Card

Yes, the "Lopis" auction above was the one that made me think of the possibility of a true dual headed card. From what I could find on the intertubes, that card has a PC VGA and Mac RGB connector, and you can use one or the other, not both.

I guess the only real solution would be to use one of the external hardware screen splitter devices, but that would be financial overkill.

A generic VGA splitter will provide mirrored monitor functionality. The multihead functionality provided by some of the Matrox external adapters requires a modern AGP or PCI Express video card that has some VESA wizardry built-in.

'They' did, but it's P/N# (there's tautology for you) 10008 Rev.#5. S/N# is blank, and 'Lapis Technologies' is mentioned only on the back, ©1990. It has DB-9 and VGA output ports.
