I noticed that the end result required but a fraction of the smallest CPLD's space (6 FFs, 10% of resources).  I checked, and GALs can't be sourced, and are more expensive anyway, so much of the CPLD goes to waste.  Since this group is probably not interested in aftermarket cart discussions like this,

Depending on how we define “this group” but to some it’s one of the very reasons to be here.

I cant’t help with suggestions “where else” but I bet this group is one of such forums ;-)

Right. In the limited world of those machine’s applications today this IMHO has to be one of the factors when designing stuff. Keep up!
