Serial Cable

I've got some descriptions for making your cable for the Sharp PC-E500. However I haven't tested any of them, so I'll want take any responsibility, whether they work, or not (or even destroy your computer)!

The first one by Craig Jackson:

Having looked at the cost of building PC-LINK.TGZ and the prices of
commercial cables, I decided to take a different approach to getting
a PC-E500 serial cable of my own working.
 
I've prepared an HTML document which describes my method and attached
it to the end of this message (two files, uuencoded).  
 
I'd appreciate it if you would make this information available on your Web
page for others which may be interested.  The design has been fully tested.
 
Thanks,
Craig

Another simple one:

I heard, that this cable may destroy your computer! However, because there is so little feedback from you, I let it here and its your decision to build it or not.

A more complex cable:

If you built one yourself please tell me your success, and which cable you've built. Thanks.
