Chipkit Users Manual

This manual provides detailed specifications, electrical characteristics, pin assignments, and timing diagrams for a set of proprietary LSI integrated circuits known as CHIPKITS. These kits (DCK11-AC, DCK11-AD, DCK11-AB, etc.) were developed to simplify the design of LSI-11 bus interfaces by reducing component count and providing a standard foundation for interface development. The document includes technical information on:

• DC003 Interrupt Logic: Logic for performing interrupt transactions.
• DC004 Protocol Logic: Provides register selection and data flow control.
• DC005 Transceiver Logic: Bidirectional buffer for data bus and peripheral device interface.
• DC006 Word Count/Bus Address Logic: Logic for DMA interfaces.
• DC010 Direct Memory Access (DMA) Logic: Handshaking operations for DMA transfers.

The manual also covers application circuits, bus drivers and receivers (8641, 8881), and the W9512 wire-wrappable module.
