Product Description
The NCR T-2193 is an ISA bus adapter card that functions as a SCSI controller, utilizing the popular NCR 53C400 ASIC. This controller was designed for 8-bit ISA slots, making it compatible with a wide range of older personal computers and workstations that relied on this bus architecture. Its primary role is to enable the connection of SCSI devices, such as hard drives, CD-ROM drives, and scanners, to systems that did not have integrated SCSI support. The NCR 53C400 chipset was a common choice for SCSI controllers in the late 1980s and early 1990s, known for its reliability and compatibility with the SCSI-1 standard. The T-2193 card would typically feature external SCSI connectors (often a DB-25 or Centronics 50-pin) and potentially an internal 50-pin connector, depending on the specific implementation. Users would need to configure the card's IRQ and DMA settings via jumpers or DIP switches to avoid conflicts with other hardware in the system. To utilize the NCR T-2193, users would need to install specific device drivers for their operating system, which could range from MS-DOS to early versions of Windows or other compatible operating systems. Despite its age and 8-bit limitation, the T-2193 served as a cost-effective solution for expanding the peripheral capabilities of many legacy computer systems, allowing them to interface with the then-emerging SCSI standard.
