This document is an Engineering Change Order (ECO) Log for the Digital Equipment Corporation LP01 Line Printer. It details two specific change orders:
- LP01-00014 (October 1972): Addressed inadequate documentation for shipping software. The correction involved updating the Obsolete Software List and adding an Accessory List to the LP01 print set. This was an in-plant documentation change.
- LP01-C0015 (September 1973): Aimed to prevent erroneous zone changes in the printer. The correction required adding a Data Products Field Change kit (#6328), which involved specific wiring changes to the back panel (212801-2) and modifications to a circuit card (212530-1) in slot 4. This change was a field retrofit, to be applied during the next preventive maintenance (PM) for a wide range of specific LP01 serial numbers. The estimated installation and testing time was 1.0 hour.
