Has anyone else experimented with the cheapie IBM card that is being sold in "Computer Shopper?" I wrote a rudimentary GPIO driver for my DN3000 that lets me read/write digital signals from the breakout box included with the board. Has anyone by chance got documentation on the analog ports - ie how to set them up and read/write them? The code included with the board is in Turbo Pascal for the IBM/PC and is pretty obtuse. The card in question is a card originally made by IBM that has 2 D/A, 2 A/D (10 or 12 bit?) and 16 digital out, 16 digital in. It sells for $195, and includes a nice breakout box that is isolated from the main bus, so you can't (in theory) fry your precious PC. I'm willing to share this code, if anyone is interested, but I'm also interested in getting more docs on the thing... Right now, my driver just handles the digital I/O - there is provision for externally generated interrupts and analog I/O, neither of which I've gotten to work, yet. Paul Anderson CAEN
