For Sale: Tested and working in December 2024.
The card came out of a AT&T 486 computer and is marked NCR Germany. I think it's a 2MB card but not positive. Some info found online:
The CL-GD5426 was a Super VGA chipset released in 1993. It was designed to work on the ISA or VESA Local Bus and allowed for up to 2 MB of video memory to be accessed. It was Cirrus Logic's first GUI accelerator chipset, having a 32-bit hardware BitBLT (bit block transfer) engine.
The core clock on the 5426 ran at the same speed as the 5422/5424 running at 80 MHz with memory clocking in at 50 MHz. The maximum resolution supported by the chipset was 1280 x 1024 (interlaced) in 256 colours. If a higher colour depth was needed, you could run a 2 MB card in 1024 x 768 at 64,000 colours or 640 x 480 in 16.7-million True Color. For the fastest refresh rate of 72 Hz non-interlaced, the chipset could be run in 1024 x 768 or 800 x 600 resolution.
Memory-wise, the chipset was backward-compatible with earlier 542x chipsets, though almost every card that used the CL-GD5426 came with either 1 MB or 2 MB of memory. These were oriented in two banks of 1 MB Fast Page Mode (FPM) DRAM. One exception to this was BOCA Research's SuperX VGA which came in three variants - the cheapest of these was a 512 KB version that was not expandable.
