Short:        A tool to view/alter RAMSEY settings.
Architecture: m68k-amigaos

                               RAMSEY
                              ========

                 Supervisor Software RAMSEY utility
                      for Amiga 3000 computers

                            version  1.02




This little program allows you to view, set, and reset the control bits
of RAMSEY DRAM controller in A3000.   This program is a replacement for
a freely  distributable  program called SetRamsey,  which seems to have
some bugs (at least the version 1.02 does).

Usage: ramsey [[NO]Page] [[NO]Burst] [[NO]Wrap] [Show]

All command line arguments are optional.  With no arguments, Ramsey
lists the current configuration of RAMSEY:

Fast1:Asm/Sources/Ramsey 8> ramsey
RAMSEY: NOPage Burst NOWrap


To get help of the command line arguments, type "ramsey ?", "ramsey ??"
or "ramsey ???".

Fast1:Asm/Sources/Ramsey 8> ramsey ???

Usage: ramsey [[NO]Page] [[NO]Burst] [[NO]Wrap] [Show]

This command can be used to set and read the RAMSEY DRAM controller
bits on Amiga 3000.

Arguments (lower case chars optional):
 [NO]Page       control page mode operation
 [NO]Burst      control burst mode operation
 [NO]Wrap       control burst wrapping
 Show           list the current RAMSEY settings



The lower case  characters of the command line arguments  are optional,
so "nop",  "nopag",  or "nopage" will all turn page mode off.  The Show
command  lists the RAMSEY  revision number  and current RAMSEY settings
including DRAM type and refresh time interval.
Please refer to Amiga 3000  techinal documentation for more information
on the control bits and their meanings.

A quote from Dave Haynie:


"The 68030 will always request 4
 longword values during a burst sequence.  However, if initial longword
 is not aligned on a quad longword boundary (A3,A2 not equal to 0,0), the
 68030 will read in data which is behind the first data it asked for.
 Since it is less likely that this data will actually be needed, RAMSEY can
 stop the burst sequence after the data with A3,A2=1,1 is accessed."
