ware converts
DOS
based applications into
EPROM
format automatically, without the need
for
special
programming
techniques.
In
addition,
Ampro's
SSD
Expansion
board,
which
matches
the
5.75" x
8"
form factor
of
the
Little
Board/PC,
can
be
used
to
add
sixteen addi-
tional byte-wide devices
(EPROM
or
battery-backed
RAM)
for larger SSDs.
A key advantage
of
the
PC
compatibility
of
the Little
Board/PC
is that it runs the thousands
of
software applications
and
utility packages developed for
the
IBM
PC. Language compilers,
debugging aids,
and
software support packages for graphics, windowing, multi-tasking, user
interfaces, etc.,
are
readily available.
In
addition
there
is a
large
and
growing
selection
of
DOS
programs targeted
at
industrial
and
commercial applications such as communications,
data
acquisition
and
control, terminal emulation, protocol conversion, etc.
The
Little
BoardlPC
is a
member
of
Ampro's growing family
of
mM
compatible single
board
systems.
These
products offer a
broad
range
of
price, performance,
and
feature alternatives
in
a consistent physical and functional format.
