seeking a PCI multio card with Linux driver

Hi,

I am desperately seeking a PCI-bus based digital multi-io card, which has
support under Linux. I see a few types from previous messages on email
lists, and on various homepages, but I'd rely on the experience of
experts. Some considerations, which would be advantageous in choosing the
card, but of course, not all of them have to apply:

- At least 12 output and 12 input, the more, the merrier
- Card still manufactured, easy to purchase,
- Anyone having experience with it in industrial applications,
- IRQ support,
- Anyone having real-time linux experience ()

The card would control a small astronomical robot (telescope): a few bits
go out with a strictly periodic schedule ("clock-drive" for turning
stepper motors via a converter electronics), most of the out bits are
continuously kept in 0/1, and changed on an hourly timescale (e.g. turning
on a device, such as a heater or fan). Some of the incoming bits generate
interrupts, most of them are simply queried to ask the status of a device. 

We have been doing this stuff with parallel ports, but ran out of space
(only 12 out and 5 in). Using more parports is kind of a not elegant
half-solution, as we need a PCI-bus parport card (ISA bus motherboards are
difficult to purchase), and have to solve almost the same stuff split up
to several ports as we could with one card.

Thanks in advance for any idea,

Gaspar
