Well, those differences certainly explain why programming them as DM74S571s will not work at all.

It sounds as though you have the makings of a first attempt at programming when you finally get the chance to do so, although I know you are busy right now. In the meantime we should hopefully get independent confirmation of your detailed algorithm, possibly several days from now.

As the other source almost certainly got their data from this same datasheet I think it only remains to be seen whether any tuning or optimisation had to be (or should be) applied for best results.
