Subject: I/O card vs linux

Greetings;

This may be OT, but can anyone advise me on a pci card thats basicly
an 8255 with a 34 pin or greater port on the card or back panel to
bring out all 3 ports, and a suitable linux compatible driver for it?

For input? Output? Both? In the output-only with low "bandwith" being
okay, just think about attaching a number of serial-in-parallel-out
shift registers to your parport. I use something like that for switching
on and off computers...

Both, to drive a small homemade cnc milling machine. I found a pci
card with 3 each 8255's on it for about 75$, but I don't think it
meets the pci std, I don't think there's a bios on it. We'll see
when it gets here.

3 possibilities: (there are more, including some with industrial
protection, isolation, etc.)

http://www.computerboards.com : PCI-DIO24 and PCI-DIO24H, $89. These are
basically a single 8255 connected to the bus through a PCI glue chip.
They don't seem to provide a driver, but I would think the board would
be set up automatically by the PCI code, and then there are just the
standard 4 ports to read/write (you just have to find the base address
theough the PCI subsystem).

http://www.ni.com : NI-PCI-6503, $145. This is a 24 I/O board, but has added
logic (like a programmable power-on I/O state). There don't seem to be
Linux drivers, but they may exist if you ask tech support. (NI is
fairly Linux-friendly - they made a LabView/Linux version).

http://www.byterunner.com : PCI-1284-P2, $39.95. This is a dual IEEE1284 PCI
parallel port card, with Linux drivers. It's not quite what you're
looking for, but it will give you 24 I/O's (16 bidir, 10 dedicated, 2
interrupts).

Hope this helps

I did find the NI site, but the $ scared me off, I'm trying to do this
on the cheap since I'm mostly retired now. I have a triple 8255
board with 72 I/O lines from Futurlec.com coming now, with surface
shipping, a hair over $70. I don't believe the output is more than
what the 8255 can sink by itself, no real buffering seems to be
visible in the photo's on their wab page. Its called the PCI8255.
The byterunner card might possibly be usable too but it didn't fall
out of the search terms I used. Bios wise, I'll find out when it
gets here sometime this week.

Thanks Stephen.
