I can't test it on my bed-of-nails text fixture without

Maybe this is a dumb point. Could you not flow solder on the contacts on 
the board and let the user choose?

Actually, there's a better way :)  (getting rid of the solder is one of 
the pains of replacing those connectors.)

There are hundreds of kinds of pins for bed-o-nails fixtures, including 
ones that are meant to toich pins (cup varieties), ones that are meant 
to touch bare metal areas like SMT pads (castle-type, I think), and ones 
that are meant to poke into empty holes, which are basically cone shaped.

These are also available in sockets - you populate the socket into the 
text fixture board, and then you can choose which type of pin to insert, 
and can repair a bent/broken probe pin by just putting in a new one.

At my old company, test jig repairs were basically eliminated when we 
went to the socketed probe pins.

This reminded me that I have seen pads on boards just for test pins.
Then I got to thinking it, would be nice to have a set of pads for d-sub

 Oh good - I'm glad I'm not the only one who has done that ;)

 Mesa has some of their I/O boards with terminal header options - the
 boards are about $20 more than their ribbon header counterparts, but the
 two 24-pin terminal plugs are about $22 *each*.  It's less than a
 (reasonable quality) breakout board, but not by all that much.

Most users would not want to have to suck the solder out of 60 
holes and then solder in connectors.  I really don't blame them, 
either!  If you really want to do it this way, I could make up
a board like that.

You might be able to find a crown type large enough to probe either 
populated or unpopulated boards. Have you tried targeting the edge of the 
hole with a crown type? Unless the fillet is very large that might work.

 Yes, I have cup-type socketed probe pins from Interconnect
 Solutions, I think, in my test unit.  I could probably replace
 the pins with different types, but there are only certain type
 of pins that fit each size socket.  These are some fairly big
 holes in the board, so I might not be able to get big enough
 pins for the empty holes.  But, probably there is something that
 would work.  But, I'd have to change 60 contacts to swap the
 fixture over from populated to non-populated terminals strips.
 That could also get to be a drag.

Apparently, Pluto is not available anymore. Are there any alternatives?
Are there firmware files available that would allow me to make my own?
Thanks.

The Pluto-P will apparently be available in December:

http://www.knjn.com/ShopBoards_Parallel.html


The interfaces supported by EMC are listed here:

http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2_Supported_Hardware


Looks like Pico Systems are the only parallel-port based alternative.
Then there are some PCI-based options, the MesaNet 5i20 comes highly
recommended but it's quite a bit more expensive at $200.


Am I the only one who wishes for a Pluto-P with screw-terminals on the
board instead of a ribbon-cable header?

I take it you are not referring to this link:
http://www.bentoni.com/PLUTO/
Which appears to be a web page monitor of some sort.

Now, this might be closer to what you are looking for:
http://www.knjn.com/board_plutos.html

Thanks to the controversy about whether pluto is a planet or not, that hit is 
36 pages down in the google search.

 Of course if you can use a PCI card then a Mesa 5i20 or 5i22 would do

Just a s a data point, to convert my universal stepper

Now that you mentioned it. I de-soldered the terminals on my UPC and put
