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.
Please send any comments, bug reports and benchmark results to

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."
