Huntsville, Alabama-based Intergraph Corp today launches three new single and dual 90MHz Pentium-based members in its TD technical desktop personal workstation family. The top range model, the TD-5 desk-side format workstation, has dual 90MHz Pentium processors and is designed for intensive computer design and engineering applications running under Windows NT. It has 512Kb zero wait state external cache and 32Mb memory expandable to 256Mb. It comes with a choice of Intergraph’s own G91 graphics accelerator, GLZ graphics or GLI graphics. TD-5 offers resolutions of up to 1,600 by 1,280 at 60Hz for 27 monitors, up to 1,600 by 1,280 at 76Hz for 21 monitors and up to 1,280 by 1,024 at 76Hz for 20 monitors. It has two integrated Peripheral Component Interconnect local bus Fast SCSI-2 controllers; 1Gb Fast SCSI-2 disk drive with internal expansion for three additional drives and external capabilities of up to seven additional SCSI devices; a double speed CD-ROM drive; an integrated Peripheral Component Interconnect local bus Ethernet controller and five PCI, two EISA and one PCI/EISA expansion slots. The TD-4 desktop model also has dual 90MHz Pentium microprocessors, with the same cache and memory specifications as well as the same screen resolutions and G91 accelerator or GLZ graphics. It has one integrated Peripheral Component Interconnect local bus Fast SCSI-2 controller and 1Gb Fast SCSI-2 disk drive with expansion for one additional internal drive and up to four external peripheral expansion module drives; a double speed CD-ROM drive; an integrated PCI local bus Ethernet controller and two PCI expansion slots and one PCI/EISA slot. This too is for compute-intensive applications running under Windows NT. The TD-3 model is for applications running under Windows NT, Windows or MS-DOS. It has a single 90MHz Pentium processor, 512Kb zero wait state cache and 16Mb or 32Mb main memory expandable to 192Mb with Weitek Corp P9000 graphic accelerator. Resolutions of up to 1,280 by 1,024 are offered, at 76Hz refresh for a 20 monitor and 72Hz refresh for a 17 monitor. It comes with an internal and external Fast SCSI-2 channel, 540Mb or 1Gb Fast SCSI-2 hard disk drive; a double speed CD-ROM drive; an on-board Ethernet and two PCI expansion slots of which one is EISA-compatible. The TD-3 will be available in June and the TD-4 and TD-5 will follow in July and August respectively. Exact pricing will be released shortly and will range up to ?13,000 for the top model.
