Bill Butler solved this "puzzle" -- I must've accidentally missed a block when I copied & pasted from the UBASIC output. The additional PDP's you found are absolutely correct, and I'll edit them into the "complete list" (hah!) ASAP. Thankfully none of those years were used as test cases for judging the contest. Many thanks for catching the missing PDP's!
