| Testing a NuBus portrait display card |
Posted by: BarnacleGrim on 2010-06-13 12:01:05
One of my Mac IIs came with a portrait display card and a DB13W3 to DB15 cable. I connected it to a High Resolution RGB monitor, but it wasn't recognised by the Mac II (I had two other regular cards in it as well). I'm guessing a portrait card simply can't drive a 640*480 monitor. Is there a way to test it? I haven't tried throwing in a VGA converter into the mix and played with the DIP switches...

The DB15 to 13w3 cable certainly works the other way around, from a standard Mac display port to a Portrait display. However, not all video circuitry in Macs will support the Portrait display: e.g., a IIvx can't do it, but an LC475 can.

I would guess what you have already guessed - that the Portrait display card is a fixed frequency (and resolution) card specific to the Portrait display.

The Display and, almost certainly the Card, is fixed at approx. 6XX x 8XX and it might be 16" resolution rotated, dunno, my APD adapter's down ATM and vixing it is way down on the hackSheet.
You can get the card to drive a multisync monitor at that res if you noodle out the connections and "roll your own" adapter/cable. All the info's out there in the DevNotes and by googling 13w3.

Too much work for a card that I don't need. I'd be happy to give it away, but I would feel bad if it turned out it doesn't work at all.

You need not feel bad about giving it to me! Especially if you have the cable! My Apple Portrait Display/EMI Distribution Unit hasn't been working since I started installing the custom adapter into a KVM switchbox!
PM me your cost for shipping & handling if you want it to go to good use! :approve: . . . 27502, BTW! 😱)

Sorry, Bunsen already snagged it. I haven't heard if he received it and if it worked, though.
