Lapis ProColorServer 24 II and System 7.5

[cheesestraws]

I have recently acquired a Lapis ProColorServer 24 II NuBus video card.  With this installed, my Q950 will boot into 7.1 absolutely fine, but 7.5 or above gets as far as being about to load the Finder (the menu bar and desktop background appear) and then apparently soft-crashes (mouse moves but nothing actually happens).

I have a driver for this card, which is version 5.4.0.  This works fine under 7.1, again, but doesn't seem to make any difference at all under the newer versions.

Does anyone have any experience with this card?  Is there a way to get it to work?

(If not, this is very annoying, as it seems to work fine under A/UX; which means I have one card that works under 7.5.x but crashes A/UX and one that works under A/UX but crashes 7.5.x.  Aren't computers wonderful...)

A couple years ago, I got in touch with Lapis’ former CEO about their SE/30 color card. He told me they never got to publish 7.5 friendly drivers for any of their cards...

Well, that's mildly annoying.  Oh well!  Into another machine it goes.

Your Quadra has better onboard video anyway.

I tend to think that, short of a dual or specialist monitor setup (e.g., when requiring 24-bit colour at high resolution, or the ability to zoom in on individual pixels for graphics work), almost any nubus graphics card is best installed in an 030 machine, if sheer video speed is the goal. That is, I suppose, what explains the demise of cards like the Lapis ProColorServer 24 II, and Lapis support beyond 7.1. By the time 7.5 came out (1993?), the Quadra and the Power Mac had left almost all nubus video technology in the rearview mirror. The golden age of nubus was the 030 era.

Having said this, the software capabilities latent in Control Panels and Extensions are often fun to play with where video cards are concerned. E.g., some of the cards with SIMM slots will allow use of that memory for more than simply driving a screen.... It is interesting to see how the more imaginative small third party vendors  extended the capabilities of machines through their nubus products.
