7008993

This document is an Engineering Change Order (ECO) from Digital Equipment Corporation (DEC), dated December 1973 (DEC-73), for part number 7008993, identified as a "Scope Cable" for the PDP-11 Family.

It addresses two main issues:

1. Problem 1: Synchronization issues with clocks within the LK40 and M7011 modules. The Correction 1 involves specific rework instructions to move pins and add a jumper wire (e.g., re-routing wires on connector P4 and adding a new wire).
2. Problem 2: Difficulties in manufacturing the cable to ensure proper strain relief at the P1 end. The Correction 2 involves updating "Note 5" which explains cable building methods.

Additionally, Correction 3 specifies updating the model and tester.

Key Note: This FCO, when installed in conjunction with an M7011 module (revision "E" or later), will cause the PDP-11/05 SCL line to slave to the LK40, thereby eliminating the need for SCL clock adjustments.

Effectivity: It applies to in-plant production (phase-in) and requires rework on all #70-08993 cables in GT40 systems in the field, specifically when slaving the PDP-11/05 SCL line to the LK40 is required and the M7011 module is at revision "E" or later.

Estimated Cost and Time: Installation and testing are estimated at 1.0 hour. Documentation costs $5.00, and parts cost $1.00. On-site labor will be charged at the current hourly rate. The kit contents are listed as PF1151 FCO/Prints And Parts.
