Thanks for the previous posts guys. Is it ok if I got more questions?:
Are there any good/cheap (as in cheapest) PCI IO boards around? - ones that can be used with QNX for real time control?
Is it necessary/ or advisable to have C libraries with them?
Are there ones with A/D, D/A and some without (i.e. just IO)?
Is it cheaper with other IO boards that are not PCI?
Is it cheaper/better to use something like PC104?
