computer recomendation?

I need something for a stepper machine that has more than one pci slot.

I was looking at D525 motherboards but they only seem to have 1 slot.

I don't need much. Just one 5i25 card would be more than sufficient. But, two $20 parallel port cards would be good enough. My problem lies in how the machine I intend to retrofit is set up now. It has 4 axis with separate high and low limits for each. It uses 2 parallel ports (2 axis/port) but uses an odd pin out that is requiring me to use x-mode to get the right input pins for the limits. Pin#1,14,16, and 17 are used for the limits. That or make some custom cables with the wires crossed. X-mode usually doesn’t work on most motherboards built in ports that I have tried, so hence the 2 cards. I have tested it some with a single parallel port card running X-mode and a hacked together cable to y to both ports on the drive. It worked fine for testing but I wanted something better for the shop environment and since we have 5 of these machines, I would like to keep the hardware simple and off the shelf (the fewer adapters and home made gadgets the better).

Here is a two port LPT card for 13.99 that uses the Moschip MCS9865 chipset

I have seen several recommendations to use the Intel Atom D525. I did some looking

Foxconn makes a couple different models. R50-D4 one appears to be common and cheap.
It is also the only one I could find with a built in parallel port.

However I have seen a few complaints about power supplies dying or burning up.

Another brand is Zotac such as this one.

Does not have a parallel port.

Long ago I thought people liked the Shuttle. I found this.

but it does not appear to even have an expansion port.

Should I gamble on the Foxconn?

would you settle for a BOXD525MW? I don't see the MO listed anymore.

I managed to find a BOXD510MO and a BOXD525MW.

I chalk it up to confusion. The 510 is an older version with a slower processor and is more expensive.
Most likely I will order the 525!

thanks
