On http://sami.ticalc.org there is a "Pip02" programmer (software),
including some programmer (hardware) schematics. The schematics are just a
7400 and a cristal as far as I can remember it.

That's not quite much. But it hasn't got windows on it, of course ;-)

I guess this means I can power it from the calc link port, if I have to :)
