The DRV11-J is a general purpose parallel interface for the LSI-11 bus. It has a basic configuration of 64 tri-state in//out lines divided into four groups or ports of 16 bit words.

There are two 4k diagnostics for the DRV11-J option. The DRV11-J diagnostic test part 1 of 2 contains a series of tests without DRV11J interrupts designed to test all logic functions and data paths made accessible with the loopback cable inserted into the DRV11-J I/O connectors.

The DRV11-J Diagnostic part 2 of 2 is a series of tests with DRV11J interrupts designed to test all logic and datapaths made accessible with the loopback cable inserted into the I/O connectors.

The DEV11-J is contained on a double heighty module. The module contains two 50 pin connectors for interfacing to external user devices.

For diagnostic testing the DRV11-J cable (BC05W-02) must be installed with 1/2 twist between the 50 pin connectors.
