Ummm .... if he has indeed two 8k chips in locations 1 and 3, that'd surprise
me a lot ... I never heard that the ZIP could work w/o tag RAM, too. If
they are in locations 1 and 2 ... who knows, maybe the ZIP is smart enough
to detect that he really only has 8k and therefore only uses 8k?

Anyway, it all sounds mighty odd .... for a 16k ZIP, you need 4 8k chips
(2 data, 2 tag).

4 in total, so two more.
