Attributes Register and Sizing DRAM sections of Chapter 3.
January 2001 In descriptions of the general-purpose software-readable header (J10/J17), such
as
Figure 1-4 in Chapter 1, information on bit 1 (SRH1) was updated to
correctly reflect the functionality of that bit.

been added to accommodate the MVME2300SC variants of the board.
The contents of the manual have also been reorganized somewhat to conform
with present Computer Group practice for board manuals.
