Unpacked it to a folder, created a file called "crafty.rc" in this folder:
My "crafty.rc" file is:

st=1530.
time cpu
name ferret
log off
ponder=on
hash=12M
hashp=6M
book random 0
egtb=4
display notime
display nochanges
display novariation
display nostats
display noextstats
display nomovenum
display nomoves
display nogeneral
epdpfga epd.epd epd.out
exit

There is a "TB" subfolder, I put the tablebases I got from your
"edwards.zip" file in there.  Btw, I have 32MB of memory.

When I get an "epd.epd" file, I put it in the crafty folder and run
crafty.  I then watch it run for about 20 seconds, 50% of the time it
crashes and needs to be restarted.

I'm having problems unpacking the 16.3 .sit file, don't know what it is.
