Hi folks...  Perhaps somebody here can help me out with this...

I'm looking for information on the DEC video board known as
the "PowerStorm 3D30," a.k.a. the PBXGB-AA, a.k.a. the "ZLX2-E1".

Digital UNIX treats it as a TGA, but it doesn't seem to behave quite
like either a dc21030 or a dc21130.  (It appears to behave more like a
21130...)

It has Digital's PCI vendor ID (0x1011), and a product ID of 0xd,
which matches neither the 21030 (product ID 0x4) or the 21130 (product
ID 0xc).  It has a PCI 'revision' field of 0x22.  It appears to be a
combination VGA and 2-D accelerator, and shows up as a PCI VGA device.


Looking at the board, it has the following "big chips" on it:

	Cirrus chip (video?) with markings:

		Cirrus Logic
		CL-GD5422-80QC-D
		35318-302E
		9502 N
		MALAYSIA-A

	IBM chip (bus interface?) with markings:

		IBM
		P3900187
		21-43826-01
		26H3574
		BTVBR09540

	Bt485A RAMDAC


Anybody?
