While thinking about the desappearing IO problems, it came to my mind that 
some time ago I designed ad built few prototypes of a PCI board that had 
something like 24 digital inputs and 24 digital outputs, as well as some 
analog input.
The board was specifically designed for a stepper control application, so 
there is onboard provision of frequency generation, counting and gating 
(the PC must keep track of acceleration and deceleration, but it is a much 
less demanding task).
The design is not completed from the software point of view, and the PCB 
have to be redesigned to fix few problems.
Probably there will be other still unknown flaws ... after all it was a 
prototype.

If someone is interested into completing this design I can release it to 
the pubblic domain. Alternatively, I can complete it and put in production 
if a sufficient number of potential buyers will show up.

If anyone is interested I can dig further seeking for schematics, and 
documentation.
Bye bye.
Mau.
