VCD-V Rastergraf Graphics Board

The Rastergraf / Peritek VCT-V, VCU-V and VCD-V Graphics Boards are based on the second generation TMS 34020 32-bit Graphics System Processor (GSP). The boards offer a high degree of on-board intelligence and functionality, as well as a straightforward frame buffer interface.

The boards are differentiated chiefly by the bits/pixel of the primary display memory and the video output sections. The VCD-V and VCU-V have 8 bits/pixel in the primary plane and the VCT-V has 24-bits. The VCU-V and VCT-V have only analog RGB outputs and the VCD-V offers both analog and digital.

The VCU-V has an 8-bit primary screen, an optional 8-bit SCSI port, and up to two pages of 1600 x 1280 display. Programmable screen resolution ranges from 640 x 480 pixels up to better than 1600 x 1280 with refresh rates between 60 and 72 Hz vertical and 31 to 85 KHz horizontal refresh rates non-interlaced.

The VCT-V supports displays up to 1280 x 1024, has a true color (24-bit) primary screen, an optional 8-bit SCSI port, and up to four pages of 1280 x 1024 display. Programmable screen resolution ranges from 640 x 480 pixels up to 1280 x 1024 with refresh rates between 30 and 72 Hz vertical and 15.7 to 73 KHz horizontal refresh rates, non-interlaced or non-interlaced, including NTSC sync compatible 640 x 483.

The VCD-V supports displays up to 1280 x 1024, has an 8-bit primary screen, both analog and digital (flat panel) outputs (digital is limited to 1024 x 768), simultaneous analog and dital operation (with VGA timing compatible panels) and up to two pages of 1280 x 1024 display. Programmable screen resolution ranges from 640 x 480 pixels up to 1280 x 1024 with refresh rates between 30 and 72 Hz vertical and 15.7 to 73 KHz horizontal refresh rates, non-interlaced or non-interlaced, including NTSC sync compatible 640 x 483.
