Greetings all; Not in a huge hurry to get this cable done as the replacement R-Pi's haven't arrived yet, but I do have the cables meeting & soldered on a smallish piece of perfboard as of 2 hours ago. Still to be made up are as many grounds as I can find on the r-pi & buss them out to the 8 grounds available in the 7i90's 26 pin connector. And the 3 source terminating R's near the 40 pin connector are still on the bench near the cable.
I made a trip to Bridgeport's Radio Shack and got some 82 ohm 1/8 watt R's for the terminators. Along with 2 rolls of their 2% silver bearing solder, and a couple bags of ring lugs to make up a star ground system in the electronics box. That particular solder can be cooked as low as 315C, so the insulation on the ribbon cable is not noticeably damaged from the soldering heat. Beats the lead-free crap like a white mouthed mule since the lead free needs 385C or more, prefereably lots more, so you have to run the heat up, and re-tin the iron before every joint. Progress, but you might have to call a surveyor & set stakes to measure it by. :) Not much use pushing until I have the R-Pi's and the x motors PSU(s). Have a Merry Christmas everybody.
