Note:
The

space,
regardless
of the
size
EPROM

used.
. The
snap-on
cover
which
comes
with
your

should
remain
on
allthe
Modules
when
they
arenot
installed
in the
HP-71.
The
cover
protects
your

Introduction
HandHeldProducts'
71MemoryModules
(M/M's)
are
a very
powerfulenhancement
for the
Hewlett-Packard
HP-7Icomputer.
The

following
configurations:
. RandomAccess
Memory
(RAM)expansion.
Hand

provides
your
choice
of 32K,64K,or
96KbyteRAM expansion.
. Erasable

(EPROM)
expansion.TheEPROMcarrierversions
of the 71M/M's allow
you
to addressup to 32
Kbytesof softwarein EPROM.
. RAM/EPROMexpansion.The 32KRAM132K

users.

Installinq the Memorv Module
Tlne
7I M/M's areenclósedin the
card-reader
port
of
the
HP-71.The installation
is very
simple.No tools
are
necessary:
1)Türn
offtheHP-7I.
2) Türnthe

andremovethe
cover
to
the
card-reader
port.
3) Removethe
plastic
insert.
4)

2) Apply
pressure
with
your
thumb
on thelower
half
of the case
while
gentlypulling
upward
on
thetop half
of the case.
3) The

o InstallingtheEPROM
Youmayinstall
up
to 32Kof EPROMin
your
71
M/M EPROM
Carrier.
ThefollowingEPROMmay
be
used:
Intel" compatible,
CMOS,
27256,
27I28, 2764,200nanosecond
or faster.
Toinstall
a32K EPROM,the'jumper"
should
remain
on the pins marked
A andB in the
photo-
graph.
Toinstalla16K
or smallerEPROM,simplylift
the
jumper
offof the
pins
marked
A andB and
place
the
jumper
over

pins
markedB and
C.

5) Turn
the
HP-71right-side-upandmake
certain
the
nameplate
of the M/M isflush
with
the
front of 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
HeldProducts
hasincorporated
several
features
withintheTI M/M'sto minimize
this
occurrence,
however
memory
lossmay
still
occur
uponinitialinstallation.

. Be
careful
notto
press
anykeys
on the
HP-71when
installing
aTIMlM.
. Make
certainthe77
M/M is
seatedfirmly
in position
before
turning
on the
HP
71.
o
Do not
force
the
TIMIM into
the
port.
The
TIMIM
willfit
snugly
butthe
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.

Once again,to
maximize the life of the battery, the snap-on
cover must be on the M/M any time the
