tems. However, extra memory is relatively
inexpehsive nowadays. If you need extra
memory for
the
programs you plan to use, you
might as well give your computer a total of 64K

the memory it came with).
Most Atari 400s come with 16K from the factory.
While Atari has a 48K upgrade board available,
it is a bit steep in price. However, 32K, 48K, and
64K memory upgrades for the 400 are available
from independent firms. Intec 's 48K unit is a

high quality are available from Mosaic Industries
and Axlon. The Intec is typically available for
under $100. Although it may be installed by any
individual who is comfortable with simple
soldering and component disassembly, such
work is best left for qualified service technicians.
A reasonable installation charge is about $ 10
to $20.
While most Atari 800s already have 48K in their
systems, those owners who would like to free
up a memory slot or who only have 16K at pres-

board has a very good reputation for reliability
and clarity of display, and it carries a five-year
warranty.
Mosaic also makes a 64K board for the 400 and
800 which is technically sound, but is of little
advantage for the majority of 400 and 800 own- _
ers. (Most programs for these computers will not
