Powergraph / Powergraph 2.0

Launched: 1991?
Bus: 16-bit ISA
Memory: 512 KB
Chipset: Tseng Labs ET4000AX
Price: $201 (512 KB)

"STB PowerGraph Ergo-VGA
PROS: Low price, fast AutoCAD performance
CONS: Menuless driver installation

At a street price of $201 with 512K of RAM, STB's PowerGraph Ergo-VGA is
one of the three least expensive boards reviewed. It's an attractive buy, offering both fast performance and nearly switchless installation.

The PowerGraph tied for first place in the AutoCAD tests. CAD performance hounds should note that this board lists for $200 less than Orchid's equally speedy ProDesigner II.

As with the SigmaVGA Legend, you may have to move a jumper or two: one for 72-Hz screen refresh at 800 by 600, and the other to avoid conflicts with your network card. When you install drivers, there are no menus; you must do so from the command line.

If you use AutoCAD and you're looking for a fast VGA board at a bargain price, the PowerGraph is an excellent choice."

1280 Graphics System

Launched: 1992
Bus: 16-bit ISA
Memory: 1 MB or 2 MB
Chipset: Chips & Technologies 480
Price: $426/$551 (1 MB/2 MB, Feb '92)

"STB's 1280 Graphics System is a very capable performer, featuring easy installation, flicker-free operation, and good color support at a reasonable cost. Its moderate $426 street price makes it a worthwhile competitor to many of the S3 boards.

Speed improvements were respectable, with Excel and Word for Windows running more than 2 1/2 times faster. PowerPoint graphics poked along at half their super-VGA clip, but that's better than with most S3 boards. The board provides 15 drivers, although only Windows and AutoCAD are accelerated; the other applications run at super-VGA speeds.

The 1280 Graphics System is one of two boards that display 256 colors at 1280 by 1024, if you invest $125 in the extra 1MB of RAM. Installation is both switchless and menu driven, making this a good value for Windows and AutoCAD users. "

WIND/X

Launched: 1992
Bus: 16-bit ISA
Memory: 1 MB
Chipset: S3
Price: $355 (Mar '92)

"STB's S3-powered WIND/X board is cheaper than the 1280 Graphics System. For just $355 (estimated street price) you get 65,536 screen colors at 640 by 480,11 software drivers, and a mouse. If you don't mind fidgeting with tiny jumpers, this is a very good product.

The WIND/X showed no speed surprises, chugging right along with the rest of the S3 boards. Expect 2 to 2A times the speed for Excel and Word for Windows and one-third the speed for PowerPoint graphics compared to super VGA.

STB's WIND/X provides flicker-free operation at all resolutions except its interlaced 1280 by 1024 mode. It's a good performer that's loaded with nice extras. Were it not for the myriad tiny jumpers, it would merit a Best Buy. But the WIND/X is still a very good deal."
