Do they support Linux now? Their ads look like they're still M$-only.
They use a parallel port interface, so it might be rather awkward to
figure out how to drive them. A dead-tree advert I have suggests
http://www.ObservantWorld.com , who make a thing called a "Data
Station" that gives you a bunch of analogue and digital inputs and
outputs and is controlled via RS232. Or you could program a PIC
microcontroller to do the job.

These might be useful (if they still work - they're from a
3-years-dead tree):

http://www.siteplayer.com (also given as http://www.SitePlayer.com )

The last two are from an article by Eddy Insam in the October 2001
issue of Electronics World describing how he built a remarkably simple
gadget enabling him to log onto his basement and read the temperature
and switch lights and heaters on and off.

The "SitePlayer" thing is a matchbox-sized module comprising a NIC chip
and a microcontroller which runs a web server enabling you to read and
write its I/O ports via a web page. It did unfortunately seem to be
the case that you needed a Windoze application to download the HTML
code to the SitePlayer module, but OTOH it uses an Ethernet interface
so it should be fairly straightforward to use a packet sniffer to see
what's going on.
