Thanks Peter. I think its time I bought/made a bigger box, and moved both bobs out to where I can access them easier. This ones a mess, with an ice cube relay on its lid controlling a vacuum cleaner and other accessories that go with adding a 4th axis. Those heavy cables from/to the socket the vac is plugged into make it difficult to pull the lid and do things. There is stepdown boards, and charge pump buckets etc in it that aren't even mounted solid. Time to make a bigger box and put both bobs in it. Just gotta get my eyes usable again. Or say to hell with the 5i25 and get a lash-up like I wound up with the on the Sheldon, a 7i90HD and 3 7i42TA's. The 7i42TA's make that a very convenient lash-up to wire up. That brings up the question: Is the motherboard parport fast enough to talk to the 7i90HD with the parport firmware or do I need to get a faster epp parport card too? Its a bigger Dell, dual core intel cpu. The spi port on the pi is faster, but I've not found an spi card for x86 machinery yet. Not to mention that cable from the pi to the 7i90 is only an inch long. Writes at 42 megabaud, reads at 25 megabaud, in 32 bit packets. The 26 pin cables in this build are now 4 feet long, likely not too good for error free data, although I haven't noted a problem from that, yet. But either the bigger "bobs only" box, or the 7i90->3 7i42's would cut that cable down to about 18", which can't hurt, and any gpio on the 7i90HD can be input or output, something that greatly simplifies the programming when one isn't limited to 5 inputs per bob. > > I don't recall ever having to make a std parport pin an input an > > input, but somethings out of whack.
