Many
of
the
mechanical
parts
for
the
Sol
Terminal
Computer
are
hard
to
obtain,
so
we
have
made
available
the
following
items:

procedures,
plus
much
additional

We
have
sent
the
source
listing
for
the
CONSOL
tm
Personality
module
software
to
INTERFACE
AGE
magazine.
This
article
is
currently
expected
to
be
published
in
the
December 1976
issue
but
publication
schedules
can
vary.
The
CONSOL
software
allows
the
Sol
to
be
used
as
a
stand-alone
computer
system
or
as
a
terminal.
The
following
commands
are
implemented:
BASIC
(executes
at
zero)
ENTER
(in
hexidecimal)
EXEC
(at
hex
address)
DUMP
(in
hexidecimal)
TERM
(terminal
mode)
TLOAD
(load
memory
from
cassette)
The Sol-PCB
boards
sold
for
$40
each
are
warranteed
for
thirty
days
against
defects
in
materials
and
workmanship.
The
warranty
is
void
if,
in
the
opinion
of
PTC,
the
printed
circuit
board
has
been
abused
during
assembly.
Warranty
is
limited
in
any
case
to
replacement
of
defective
printed
circuit
boards.
Processor
Technology
can
not
provide
direct
support
via
telephone
or
letter
to
Sol-PCB
purchasers.
The
documentation
provided
should
be
sufficient
to
easily
build
and
debug
a
Sol
unit.
NOTE:
please
do
not
make
parts
substitutions!
If
you
are
in
any
way
dissatisfied
with
your
unassembled
Sol-PCB
please
feel
free
to
return
it
to
us
postpaid
for
a
full
refund.
Have
fun!

Due
to
layout
errors
connections
to
pins
28,
73
and
74
have
been
"
interchanged.
These
signals
are
used
by
DMA
and
interrupt
devices.
Correction
requires
three
cuts
and
installation
of
three
jumpers.
Use
24
gauge
wire
supplied
with
the
kit
for
these
changes.
1.
Cut

on
rear
side
of
board
connecting
pin
1
of

directly
below.
Install
jumper
wire
on
rear
side
of

connecting
pin
1
of

73
of

connecting
the
feedthTough
adjacent
to
pins
13
and
14
of
U64
with
the
feedthrough
directly
above
(on

Install
jumper
wire
as
shown
on
the
rear

3.
Cut

connecting
the
feedthrough
innnediately
below
