Two kinds of 16k cards were popular:
a) Apple Language Card
with 16k RAM and a socket for an Autostart Monitor F8 ROM. This card was
sold with The Apple Language System (=UCSD Pascal).
b) Microsoft 16k Card
with 16k RAM and three LEDs to indicate read enable, write enable and
bank 0/1
Both cards have been cloned by many companies in the far east, therefore
many different versions of these two designs exist.
