FCO 882BA-R003, Retrofit VAX 8800 systems to rev "D1"

Order Number: FA-04779-02

This Field Change Order (FCO 882BA-R003), released in July 1987, outlines the procedure to retrofit all VAX 8800 systems to Revision Level "D1." The FCO, incorporating ECO BT-ZMAAD-C3-LK002, addresses several issues including:

  1. Fixing remote port character loss and "Disable Local Console" command.
  2. Ensuring I, U, and START commands can only be initiated when the machine is halted.
  3. Requiring the full word "TEST" to invoke micro diagnostics.
  4. Preventing system crashes when the PRO is powered off (requiring Console Rev "22E" and VMS V4.6).
  5. Resolving "Read Retry Timeout" errors in the NBIB related to interlock devices on the BI, via a CPU microcode change.

The installation is estimated to take 3.0 hours and involves shutting down, powering off, then powering on the system, followed by running VMS and UETP. It notes that Console Rev "22E" and the Read Retry Microcode are not included in the standard EQ Kit, but Console Rev "22E" (part ZM920) can be ordered separately. The console upgrade procedure does not include instructions for reloading diagnostics onto the console hard disk, which may need to be done manually. This FCO affects an estimated 882 VAX 8800 systems.
