National Instruments PC-DIO-96 Digital I/O Board for ISA
Features

• 96-Bit Interface
• Unidirectional or Bidirectional
• Four 82C55A Programmable Peripheral Interface Chips

The PC-DIO-96 is a 96-Bit, parallel, digital I/O interface for ISA computers. Four 82C55A programmable peripheral interface (PPI) chips control the 96 bits of digital I/O. The 82C55A can operate in either a unidirectional or bidirectional mode and can generate interrupt requests to the host computer. You can program the 82C55A for almost any 8-Bit or 16-Bit digital I/O application. All digital I/O communication is through a standard, 100-pin, male connector. The PC-DIO-96 also includes an 82C53 counter/timer that can send periodic interrupts to the host system.
