Rastergraf's VCL-M/8 is a single board 34020-based graphics display controller for PMC equipped VMEbus, CompactPCI, and other PMC/PCI Bus computers.

The VCL-M/8 includes an 8-bit overlay. The overlay screen can remain static while the primary scrolls (or vice versa)

The display memory which is used for the primary and overlay can be combined to support either primary-only double-buffered or high pixel count (e.g. 2048 x 1536) displays.

The 40 MHz TMS 34020 32-bit Graphics System Processor draws random points at a 10 Megapixel per second rate, and normal pixblt, pattern fills, and vector generation at up to 40 Mpix/sec rate. Hardware acceleration features include color and writemask registers, VFILL, and VBLT, and can give up to 160 Mpix/sec on a block write.

The display size ranges from 1 million up to 4 million addressable pixels. Display formats include 640 x 480, 1024 x 768, 1024 x 1024, 1280 x 1024, and 1600 x 1280.
