the
QUARK
family of single board microcomputers
The
QUARK
family of microcomputer products comprises a
number
of high-performance single
board computers
and
support software,
all
designed
and
manufactured
by
Megatel.
Quarks
are
designed
to
provide a II the
work

funct ions of a basic
computer
on
a single,
compact
board
for the
end
user,
computer
OEM

software systems
are created
as
flexible
and
complete
components
which
allow
their
users to skip
most
of the
expensive
and
time-consuming steps
in
their
systems design,
programming
and
testing.
QUARK
hardware
is
designed
to
minimize space requirements
and
parts
count, while
si
multaneously maximizing processing power, speed,
and
flexibi l
ity.
The
architecture of the
QUARK/100
serves
as
the "template" for the enti
re

and
I/O features.
The
QUARK/100
is
avai lable
in
3 models,
64K,
1281<
or
2S6K
of
RAM.
The
QUARK/1S0
adds
RGB
color
capabi
l
ity
to
the
QUARK/100's
list
of
features.
The

floppy disk capabi l
ity
by
providing
direct
control
of
ST-S06-type Winchester
hard
disk drives.
The
Quark/400
combines
all
of the features of the forementioned boards
and
adds
real a time clock with battery backup,
EPROM
and
EEPROM
support, yet
you

fLoppy
disk
and
in
a
form
which
aLLows
it
to
boot
up
immediateLy
assuming the
"lowest
common
denominator"
in
user hardware.

interface easi
ly
with
most
8-,
5.25-,
and
3.S-inch floppy disk
drives.
You
shouLd
be
aware, however,
that
disk
drive
specifications
vary widely from
manufacturer to manufacturer.
Megatel
has
tried
and
tested a variety of floppy disk drives
and
the
foLLowing
is
a
list
of drives
which
we
recommend
as
being particularLy well-suited for
use
with the
QUARK.
