Flip chips, M series and all were really dictated not by what could be put
on a board but how many connections the bord could make. For a flip chip
it was 18 or 36 (someone?). A 16 bit parallel load register like say a
pair of LS573s would need 32 IO, plus power and controls. See the
problem?

Even TTL chips hit the wall in pins/functions per package.
