fusible link pats at one point, probably accompanied by a change in
part number. They all read the same way, of course.
Okay, I went and dug through my tubes of ICs and found them. They're
TI TBP18S22N units. I don't know how the programming compares with
the National parts.
I'm going to have to itemize the stuff in my hellbox one of these
days...
