chips

These parts aren't PAL chips FOR a specific application. They're about
10-year-old electrically eraseable and reprogrammable GAL (generic arraly
logic) parts, intended to become lower-cost replacements for the bipolar
PALs. In the latter purpose they have been quite successful, in that I
seldom even see a bipolar part in boards less than 15 years old. The
advantage, of course, is that these have a more flexible architecture and
variable macrocell design than the original PALs, say, from MMI, had. Of
course there are only a few of them that are asynchronous, and those,
typically, are just copies of the 20RA10 in more current technology.
