I/O card vs linux

I/O card vs linux

[Gene Heskett]

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.)

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).

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).

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.
