There is the Fluffy programmer under :

http://www.codepuppies.com/~ben/sens/pic/sx/

It uses a PIC connected to the serial or parallel port to generate the
timing. Supports PICs and SX28, not sure about the SX52.
I have tried to build it, but had no luck, it did not work...

Scenix has published a ISP programmer with free Software for their
SX chips under:

http://www.scenix.com/virtual/download/isp.html

The circuit seems a little bit to complicated for this purpose to me,
i don't trust a windows program for generating accurate timing on the
parallel port, but IT WORKS for me.

There is a tricky part in installing the software. A workaround was
described in the Scenix newsgroup. I also have made some changes/
improvements on the schematics.

If you are interested, let me know. I can mail you the details or
even put all changes on a WEB Page.

Hope this helps ...
