Bummer, the chip Hodd referenced is not too difficult to fix up on a small board. He even set me up with one so you know it's simple.
Got some pics somewhere, will find them later.
Good thing is, you can possibly arrange the screw terminals on the board to match the BoB and use 14 ga solid copper in short length for mounting.
Later,

Around page 7 of this post has some pretty good info.

Thanks RC!  Had to pick at you a little.  Sent you a PM.

Cool Brett, thanks.
Here is the pic of the one Hood helped me set up.

Ok gentleman,
    I've looked at the threads linked related to making your own differential line drivers. Looks to me like the ones made by Hood were custom PCB's MADE by Hood,same for the one from BR549,way outta my league. BTW, the one Hood showed with the DB 25f connector & everything labled on the board is as "factory made" & professional as anything I've ever seen,WOW,impressive indeed. But I don't know squat about making a custom PCB, ugly or otherwise.
    If I see correctly the one Overloaded made seems to possibly be on some kind of "off the shelf" universal type board. If that is the case where does one get such a board,the screw terminal connectors,sockets for the chips, etc. How would a know nothing about electronics guy like me come up with a ''stock list" of componets needed so I would be ordering everything I need the first time & nothing I don't need?
    I'm a diy & save a buck kinda guy & if I can't get the drivers from cnc4pc I guess I'll have to attempt to make my own but I gotta tell ya, for $4.25 each this is one diy project I'd be fine with side stepping.(;-)

UGLY ! ! ! !    Hey ... it works. ... and I was pretty proud of it, being I was more intimidated than you at the time.  (just funnin', no offense taken.

Mouser, Digikey or Allied for the IC's, Radio Shack for the board and screw terminals. The shack can get the IC's too if you want them to, here anyway.
It's really simple after studying the data sheet of the IC. I didn't use any sockets, just soldered the IC directly to the board.

They appear to be IN Stock over yonder.

Might check, the shipping is not to bad ... sometimes.

Just an option,

I think I may have one of the ones I made up that I probably will never use again, if interested give me a PM. It will be one of these ones, see below.
Hood

You betcha I'm interested, PM sent.

I don't want to or intend to insult anyone but YOUR'S ain't the one I was thinking of.
