Well yes, but that was 30 years ago and I've slept some 11,000 times since then. :sleep:

So my memory won't be much help. :scratch:

I believe I sent you an ET-248 schematic, but I suspect that Eagle never got around to writing the ET-248 manual since we had lots of those units, but never a manual. Except for adjusting cycle lengths, intervals and offsets, I don't think these things were typically field programmed. Eagle probably had one or two engineers who programmed every ET-248.

Unless you have the original prints on your cabinet, including the original ET-248 cam chart, I'm afraid you are in for an epic reverse-engineering job.

I got the 3 phase ET-300 cabiner print and a ET-310 print from you and a Et 300 book and oil maintance paper. The ET-248 I got from a guy in Ohio with a print for it. It show is was for a 6 phase set up and guess what the cabinet is a 6 phase. So today we hooked up the Et-248 filled the one dial with all the pins I had in a Ef-20 controller and it works fine in this set up. Found out the Et-300 will not max time out unless the Et-248 is plug in as all the max times goes throught it. I have no offset pins at this time so I can not get that part to work. Also going to mod some EF-20 dial units to replace the other two that never came with the ET-248 controller. Then to find more pins. Going to shack store and get 6 test clips so I can max out all the ET-300 to make sure the ET-248 does what it is set up to force the controller off max when it gets in that phase.

then on to building a light board.

thanks all
John
