Does this machine have a std pci slot? If it does, a Mesa 5i25 card will give you a pair of parports, independent of the machines own parport, and do it with more i/o bandwidth than you'll get from adding another parport card. I have 2 machines setup with the 5i25, and both work well. A 4 axis G0704, which uses both ports and and a 7x12 lathe that so far is only using one of them. You can use 2 more or less std parport breakout boards, and I highly recommend the SainSmart boards for that as they have no signal distorting opto-isolators in any output. They do isolate the inputs however, which limits the speed of any spindle encoders involved unless the opto is snipped out of the circuit and bypassed in those two inputs. I am an old C.E.T., so thats easy for me to do. I have no clue if Peter (mesanet) has a pci-express version of that card. You might ask, or an old off lease Dell usually has a pair of pci slots, and can be had for less than a 100 dollar bill from places like pcliquidater.com. Another, more pricey way might be to use a 7i90HD and a trio of 7i42TA's, which are required to protect the 3 volt circuitry of the 7i90, which I am running a converted Sheldon 11x36 with, that gives you 72 gpio's and several choices of FPGA configs. So I am doing what needs to be done to run this lathe and still have around 25 gpio's I haven't used. This card can be driven from a parport, or from an SPI, which I am doing from a raspi 3b on that machine. I hope this helps, yomin estiven jaramillo munera, where are you? -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
