I really don't want to re-invent the wheel if possible...

I have a board (actually Tutankham) which has multiple 4116 failure... I think something traumatic must have happened to some of the power rails in its past.

I am thinking of replacing the eight 4116s in a row with a static ram and some latches but obviously there is a certain amount of complexity with the timings.

Has this been done before? Is it open source?

Thanks in advance
