Thanks Mitch a copy would be great.

The problem was one of the transistors not functioning properly so was feeding the same digit info to two displays causing one to fail and the othr display very b right garbage.   I found this because with the one display unplugged one of the digits was brighter than the other found which strobe controled it and cut off the transistor and all display came good except for that digit
