_ DEC-O-LOG for KC750

_ DOL, KC750-R0001, KC750 Keyswitch SEP 83

PROBLEM: The KC750 option is not secure when the keyswitch is in the Remote/
Secure position.  This can allow the memory of a running system to be modified
from the remote port even if the keyswitch is in the Remote/Secure position.

CORRECTION: 1.  Lock module's DMA port in either Local/Secure or Remote/
		Secure position (one etch cut and two wires).
            2.  Lock remote port DTR in either Local or Local/Secure position
		(one etch cut and four wires).
            3.  Add new serial number tag to KPL.
            4.  Correct CS-L0006-DM12, VA-L0006-00 and DD-L0006-00.

IN-PLANT EFFECTIVITY: Febuary 19, 1982

FIELD EFFECTIVITY: Retrofit all KC750's to Unit Revision Level 1.  The
	minimum acceptable revision levels of L0006 modules in spares stock is:
             Etch Revision "B" CS Revision "B1".
             Etch Revision "C" CS Revision "D".
	This FCO incorporates ECO L0006-00004.


QUICK CHECK: Check for ECO wires on E6-3, 4; E12-12, 13; E133-12, 13, 14,
15; E176-24; and E187-5.  ALso check for Etch cuts on side two near
E42-13 and E187-5.

The DEC on-site labor charge will be the time required to install and test
the FCO at the then current hourly rate.
