38 I'm greedy. can i triple my ram? (Miscellaneous Macintosh)

You need RAM Doubler 1.0.1 or 1.0.2 for this trick. You can't
do this with RAM Doubler 1.0, 1.0.3, 1.0.4 or 1.5. Turn RAM doubler
off and reboot your Mac. Then open RAM Doubler with ResEdit. Open
the "Main" VCMD resource and use ResEdit's Find command to find the hex
digits A868. Just before these digits are the hex numbers 0002 0000.
This is a hexadecimal fixed point number that tells RAM Doubler how
much to multiply the RAM by. Change it to 00030000 for a RAM tripler,
00040000 for a RAM quadrupler, and so on. Then restart twice. You
will now have even more RAM. Of course the more RAM you ask for,
the more likely it becomes that RAM Doubler will need to use virtual
memory to meet your RAM demands thus slowing down your Mac. For large
quantities of RAM Apple's virtual memory is faster than RAM Doubler.

You can also use fractional multipliers as long as you remember that
the number you're changing is a hexadecimal fixed point number with
the "hexidecimal point" between the second and third bytes. For
example two and a half would be 00028000 which would make a "RAM
Double-and-a-halfer"

This trick is even easier with RAM Doubler 1.0.1. Instead of opening
the VCMD resource open the 'pref' resource. This resource contains
several fields. The one you want is called "multiplier value." This
field contains one hexadecimal fixed point number, 00020000. Change
it to 00030000 for a RAM tripler, 00040000 for a RAM quadrupler, and
so on.

Spencer Low's five dollar shareware product MaxRAM wraps a nice
interface around this procedure for those who aren't comfortable
exploring the bowels of their software with ResEdit. More
importantly MaxRAM even works on RAM Doubler 1.0.3 and 1.0.4 (though
not on RAM Doubler 1.5 and later :-(). See
