Mystic with LC video card
Posted by: nickpunt on 2019-02-27 22:01:14
I have a mystic (575 board) color classic and just acquired a rather large LC video card called the Lapis ProColorServer 24 LC. It's physically much bigger than I expected, to the point where it gets in the way of the 575 board's VRAM. 

I could probably make this physically fit by building a riser with a few M-F euroDINs, but before I do that, I have a question: has anyone ever tried any LC video card in a mystic? 

This card has a 68882 on it, so I'm definitely popping that off before any trial run just because that's unlikely to play well. The card is (c) 1992 so a product of the LC II era, 2 years prior to the 575. 

As you can see from the images, it's nearly the size of the 575 board itself:

On top of the 575 board, you can see that if installed, the card would hit the VRAM on the left:

And a view from the side:

I have my answer: yes it is possible to use an LC video card in a mystic. Thanks 3-years-ago @pcamen. 





Next step is to figure out whether I can get a Dual PDS solution going for IIe card + video card mystic:

The IIe card requires 24 bit addressing no?  Is the 575 board not 32 bit clean?

It's supported on the 575 but only in 7.5.5 or older Mac OS since you can use either 24 or 32 bit addressing.

Not the main subject of the post but com slot Ethernet and IIe won't coexist (IIe card won't work)
