Diamond Speedstar?
The Diamond Speedstar 24X has the Western Digital "WD90C31" chipset.

Notes
1) This package contains various things, including a Windows 3 driver. When you install it, you can choose between the Speedstar driver (max resolution choice of 1024x768x16), and something called a Turbo driver. The Turbo driver gives you the extra choice of 1024x768x256 colours. I wonder if this is because the card has extra RAM added to the RAM sockets? I wonder why they call it a turbo driver? Forgive my ignorance, but I think this card has no 2D acceleration. If that is correct, then there's nothing "turbo" about this Windows driver. I ran WinTune 2.0 for Windows 3, and it was terribly slow.
