Multioption Card with 2 RS232C Interfaces

Summary

This document is a technical manual for a "Multioption Card" developed by MICO GmbH for use with PDP-8e and PDP-8a computer systems. The card functions as a dual-channel serial interface (V24/RS232C) based on a Z80A microprocessor system, providing high flexibility for connecting peripheral devices such as terminals, printers, and paper tape readers.

Key features and capabilities include:

• Performance: Supports full-duplex communication with data transmission rates up to 9.6 KB.
• Hardware Compatibility: Fully compatible with DEC hardware standards; connects via the Omnibus interface.
• Customization: Includes options for 20mA current loop interfaces, up to 4KB of onboard RAM for data buffering, and support for hardware/software handshaking protocols.
• Configurability: Users can adjust baud rates, device codes, and data formats (parity, bit length, stop bits) via onboard switch settings.
• Technical Details: The manual provides comprehensive installation instructions, jumper/header wiring diagrams, and detailed electrical schematics to assist in system integration and customization.
