is very
simple.No tools
are
necessary:

of the case.
3) The

o InstallingtheEPROM
Youmayinstall

ThefollowingEPROMmay
be
used:

or faster.
Toinstall
a32K EPROM,the'jumper"

certain
the
nameplate
of the M/M isflush
with
the

HP77.
6) Replacethe cover to the card-reader
port.

Note:
¡ As with
any
plug-in
module,
thereis
a chance
of
memory
lossin the
HP-71
wheninstalling
a 71 M/M.
Hand

hasincorporated
several
features
withintheTI M/M'sto minimize
this
occurrence,
however
memory

still
occur
uponinitialinstallation.

. Be
careful
notto
press
anykeys
on the
HP-71when
installing
aTIMlM.
. Make
certainthe77

o
Do not
force
the

the
port.
The
TIMIM
willfit

sockets
on
the
71M/M must
be
properly
aligned
withthe
pins
in the
HP-71.
7l M/M's . . . EPROM Carrier Versions
TheTl M/M's offer two options
for adding
EPROM to
the HP-71:
the EPROM carrier
by itself
or the EPROM
carrier with 32K of RAM. The EPROM functions the
samein both versions.
o Opening the case
The7l M/M's are
enclosedin plastic
cases
which
have
been
designed
to allow
easyaccessinside
the
Modules. Hand Held Products has utilized
a
specially-designed
adhesive
tape
which
acts as
a
hingefor the case.
Do not remove the tape-the
case opens at the opposite end. To
open the
case:
1)
Grasp
the caseas indicated
in the photograph.

These

upon
"worst-case"
conditions.

Once again,to
maximize the life of the battery, the snap-on
cover must be on the M/M any time the
Module is outsidethe HP-71.
Note:
