Stuffing an LC video card in a Color Classic mystic

I've got a color classic with a 575 board in it and haven't done the video mod (no 640x480 yet).

Since I have a comm slot ethernet board, it occurred to me to try and find a video card for the LC style PDS slot on the 575 board that might fit.  Wouldn't that be nice, a Color Classic with a 68040, ethernet, AND external video! 

I found an LC Radius Pivot card, but it is too long to fit nicely; it is held up on the side opposite the PDS connector as it rests on top of the RAM (or VRAM, I forget which). 

What would solve that problem nicely is about a half inch PDS slot extension - just a straight pass-through that raises the PDS connection up a bit.  It appears that at that height it will still fit (barely) inside the MB housing, and nicely leave some clearance for the new battery that is sitting there. 

Anyone tried to build something like that?

I seem to have stumbled upon the perfect solution.  I purchased a 96-pin connecter made for through-hole mounting on a PCB, exactly like the one that is on the LC-575 board.  The solder pins fit nicely in the existing PDS slot and the board sits on top perfectly flush now.

I believe this is called a Euro-DIN 96-pin connector.

As far as I can tell (http://www.lowendmac.com/tech/pds.shtml) the LC PDS slot on the 575 board can accept the same cards made for the original LC ... my Radius Pivot card mentioned above.   I just happen to have two Pivot monitors, one greyscale and one color.

Here are a couple more photos of the thing inside the LC.  Tight, but seems to clear

The Pivot monitor will show the correct orientation if I start the system either in landscape or portrait mode, but it won't switch on the fly.  Given that I have a Radius Pivot LC card, I thought this was handles by the hardware and no drivers were necessary (I didn't install any). 

Does anyone know if there is software / driver(s) / extension(s) required to adjust the video orientation when pivoting on the fly while the computer is running?

this is the kind of thing that could make jt fall in love with the CC,   even though he hates the CC,  LOL.

How could anyone hate the cute little CC? It never hurt anyone! I have a plan to make a flat screen little tribute to my favorite 68K machine :D

Color pivot!  I'm so jealous.  Try installing the drivers.  The neat thing about the pivot is that you can switch between the modes on the fly without restarting.

It has a hardware switch, but it still needs the software to dynamically change the desktop.

Very cool. I wonder if you could stack this on top of a IIe card, using a F-F euroDIN connector attached to the pins coming out of the top of the IIe card. See photo for something similar example (apologies for using 120pin rt-angle eurodin adapter, it was what I had). I believe people have done this type of thing to make a basement for SE/30.
