Extendable
bus
interface
>Don, you mentioned that the 72 pin connector is ISA,
but multiplexed.
... Difficult... I looked at hacking ISA bus cards onto
the Convertible
bus. the main problem is that the address and data lines
are multiplexed
to get it all on the connector. You need extra logic to
separate the address
and data lines. I visualise a CRT slice (in this part of
the world, they
were cheaper
and more common than the serial/parallel slice), with
the CGA logic
removed, and a slot in the top of the slice with an ISA
riser sticking
out. If you have the upgraded power supply (originally
released with the
backlit LCD option, but standard in later production),
you should be able
to run at
least 2 ISA adapters if they aren't power hogs. Anyone
got the schematic
diagrams for the CGA slice?
Floppy Drive
3.5" 720K Toshiba 4452A0P11
with a 34
pin edgecard connector. Both drives are jumpered DS1
3.5" 720K ALPS
DFL413C02B, 34 pin
edgecard. There are two jumpers on the top- SW1 (right
rear corner) is
jumpered "1", J1 (center-left front) is jumpered "B-C".
Floppy bezel snaps on drive case.
I have used
an 8580 cardedge floppy with the big button- slipped
right in, bezel snapped
right on (now to figure out how to get 5140 to
recognize 1.44!). I see
no P/N or FRU on it.
From Don Hills
There were 2 models of floppy drive:
Toshiba and Alps.
The Toshiba used a metal band to drive the heads up and
down, the Alps
used a leadscrew. The leadscrew model could not step the
heads at the full
stepping rate of most PCs, so the stepping rate was set
slightly slower
in the BIOS. Trouble was, the metal band type drive was
designed for full
speed, and was very noisy when seeking at the slower
speed. I wrote a small
driver that loaded (and unloaded again) during boot to
reset the step speed
on machines with the faster drives. The drives looked
identical externally,
you had to look in the slot or remove them from the case
to see the difference.
Battery
Pack
PN 2684331 9.6v, 1.8AH
From Gfretwell:
There were some guys on
the VM 5140
Forum who talked about how to cut the battery pack apart
with a Dremel
and replace the cells with industry >C cells. There
is also a fuse in there.
From Don Hills
I was one of those
guys. If you
couldn't get the "sub C" cells, the trick was to use
standard C size cells
and duct tape them into a pack the same shape as the
original. This "naked"
pack fitted in the same space as the original
pack-plus-case. The battery
compartment was all plastic so the new pack was well
protected. Use Standard
charge rate cells.
Consider standard C
cells (with tabs)
instead of sub-C, if they are cheaper yet. The only
reason for sub-C cells
is that they will fit back in the battery case. I used
standard C cells
(not even solder tabs, but I am good at
soldering).
Of course they did
not fit in the
case, but I wired them up in the same physical pattern
to the old cells,
re-using the connector and thermal fuse from the old
battery. Then I placed
strips of cardboard where required between the cell
ends to stop them shorting,
sandwiched the cells between two sheets of cardboard
cut using the old
case as a template, and bound the whole lot in plastic
insulation tape.
This package looked
untidy, but fit
just fine in the battery compartment. Since the
battery compartment is
a complete plastic box in its own right, the original
battery pack casing
is not essential.
Open the pack with a
hammer and chisel.
Clamp the pack on its side lightly in a vise with a
piece of wood under
it for support. Or, take a piece of scrap lumber and
nail 2 short bits
of 2x4 to it spaced so as to snugly hold the pack on
its side. Apply chisel
to the case join and tap a little harder each time
until it cracks. Start
at a corner and work around the pack.
As for the power supply, as I said in an
earlier post there
was a US-only 110V "wall wart" that was only powerful
enough to charge
the battery when the system wasn't running. There was
also a universal
(100 to 240 volts) power "brick" (P/N 2684292) much like
those used on
modern laptops, that provided enough power (15 volts DC,
2.7 amps) to run
the system and all accessories while charging the
battery.
The plug is the type that has a metal
outer barrel as one
contact and a metal-lined hole down the middle (Center
positive)
that is the other contact. Size: now pay attention here.
5.5 mm external
diameter, 2.5 mm internal diameter. They also come in
2.1 mm internal diameter,
so don't get
the wrong one.
BATTERY CHARGER (#4060):
A 110-volt input feature designed to be used to charge
the internal
batteries of the system. It does not provide
sufficient power output
to allow system operation while the batteries are being
charged
AUTOMOBILE POWER ADAPTER
(#4065):
Designed to charge the system battery while allowing
simultaneous use
of the system unit. The adapter attaches to the
system unit and plugs
into the cigarette lighter outlet in a vehicle with a 12
volt negative-ground
electrical system.
Opening
the 5140
From Don Hills
Open the battery compartment door and remove
the battery.
This is important, as many parts of the machine such as
the memory chips
are permanently powered so long as the battery is charged.
The battery
catch is on the bottom of the plug (like a modular phone
plug).
Open the display by pressing the two small
grey buttons
under the carrying handle at the front right and left
corners of the case.
If you don't use the catches, you might snap off one of
the small retaining
catches on the LCD screen bezel. Pivot the display
backwards until it is
just past vertical. Press on the front bottom (notice the
neat-o vertical
serrations?) of the plastic plate covering the front of
the display's "neck"
until the plate pivots away from the neck, then lift the
display up (wiggle
it slightly side-to-side). This feature is why it's called
the "Convertible".
Undo the 4 screws on the rear of the case.
Lift and remove
the rear (non pivoting) part of the top cover.
Pull the grey carrying handle forward,
exposing 2 small
slots in the case. Use a small screwdriver or coin to
press inside the
slots while lifting up on the front of the keyboard. Be
careful not to
damage the foil cable. Don't try unplugging it yet, just
move it forwards
and lay it on the extended handle.
Note that the keyboard pivots on two small hinges at the
front of the
lower case.
Undo the 4 screws holding the diskette
drives in and pull
the drives out. Thumb in the diskette slot, fingers
underneath is the best
grip. Note that the floppy drive bezels have catches
that fasten them to
the drives. They are not loose!
Reach in through the diskette drive bays
with one hand
and through the opening at the rear with the other, and
unclip the diskette
drive plugs from the clips on the underside of the
(pivoting) top cover.
Lift the rear of the pivoting top cover
and slide it forwards
until the pivot pin at the front disengages from the
slot it slides in
and lift the cover up and away, unplugging the foil
cable to the LCD socket
as you do so.
You can now unplug the keyboard cable.
Reassembly is the reverse of the above, just 3
tricks:
When screwing the diskette drives back in
place, BE EXTREMELY
GENTLE. The screws must not be tightened too much- you
will crack the drive
front plates and/or break the plastic pillars that the
screws go into.
THEY
ARE VERY FRAGILE. (Ed. They were cracked on
mine)
From Us, the god-Emperor of Microchannel
I found that getting the LCD unit back on
was interesting.
Note that the LCD swings on a "trapeeze" that has a
metal pin going through
it. Note the two ptllars that come up on each side of
the floppy and LCD
headers. Notice the arc made by the top of those
pillars. See the groove?
Notice that the open end is toward the front.
What I did- lower the LCD neck to about
halfway forward.
This lowers the cross-pin. Looking from the back,
directly over the battery
well, you can see the shaft AND the grooves. Now you can
actually SEE how
to position the top so the shaft will slide into the
grooves.
Back to Don
When replacing the keyboard in its well,
make sure the
edge nearest the diskette drives sits on (not under) the
small ledges moulded
in the front plates of the diskette drives. These ledges
lift the keyboard
to typing position when the case is opened. If you get
it wrong you may
break things when you try to close the case. The
front corners of
the keyboard have little pivots that mate with the front
of the bottom
case. I had ot push down lightly
to make them
"snap" in place.
As for piggyback accessories, there were several. They
were known as
"slices", because they were the same profile as the back
of the machine
and when clipped on looked like an extension of the
machine.
A few additions to your page:
There was no way of powering the system off completely
without removing
the battery. Some parts of the system, including the
memory and much of
the planar, were continuously powered. Being static CMOS
logic, they consumed
negligible power when not being clocked. The battery
would hold the memory
(and run the clock, there was no separate clock battery)
for a couple of
weeks. There was no suitable CMOS diskette controller
chip so it used a
standard NEC 765. This was power hungry so was actually
powered off when
not in use- the BIOS saved and loaded the controller's
state between drive
accesses. I've got a lot more somewhere, including info
gleaned from conversations
with the actual developers, and the full IBM Tech Ref
and Hardware Maintenance
Manuals.

DESCRIPTION
The 5140 is
available in two models.
The model 2 is equipped with a CMOS 80C88
microprocessor, 64Kb ROM, 256Kb
RAM, an 80-column by 25-line detachable liquid crystal
display, two 3.5-inch
diskette drives, a 78-key keyboard, an AC adapter, and a
battery pack.
Also included are an Application Selector, SystemApps,
Tools, Exploring
the IBM PC Convertible, and Diagnostics.
The model 22 is the
same as the
model 2 with Diagnostics only. Both systems can be
expanded to a maximum
of 512Kb RAM via 128Kb RAM memory card features, and may
include an asynchronous
modem in the system unit. The Model 003 has a
backlit LCD and uses
256K memory cards.
At the back of each
system unit
is an extendable bus interface. This 72-pin
connector allows any
or all of the following options to attach to the base
unit: Printer, Serial/Parallel
Adapter, and CRT Display Adapter. Each of these features
is powered from
the system unit. The CRT Display Adapter operates only
when the system
is powered from a standard AC Adapter. A separate CRT
display or television
set attached via the CRT Display Adapter requires a
separate AC power source.
128KB MEMORY
CARD (#4005):
This card uses (16) SRM2064M-15 chips for 128K.
256K MEMORY
CARD (#6030)
This card uses (8) SRM20256M-12 chips for 256K.
From Don Hills
System memory was 640 KB max, with 256 KB
as well as 128
KB cards. Any combination could be used up to 640 KB. To
reach 640K with
128K cards, several people built a short ribbon cable to
extend the last
card's end connector to another 128KB card which they
laid on top of the
others under the keyboard.
That was too tight for my liking, so I
actually ran the
ribbon cable through to the modem slot and put the 5th
card there.
> Was the 640 max due to DOS limitations?
From Don Hills
Hardware limit. Any addresses above 640 KB
weren't passed
to the memory cards, they were placed on the bus instead
for devices like
the CGA video memory.
PRINTER
(#4010):
Attaches to the back of the system unit, or
to an optional
printer attachment cable for adjacent printer operation.
It is an intelligent
cpu-based, 40 cps (burst rate) serial, non-impact dot
matrix design capable
of low power operation. It draws its power and control
from the system
unit. Standard ASCII 96-character, upper-case and
lower-case character
sets are printed using a high-resolution, 24-element print
head.
An all-points-addressable (APA) print mode for graphics is
also provided.
NLQ printing can be accomplished using either a thermal
transfer ribbon
on smooth (60 Sheffield units, maximum) paper, or no
ribbon on heat-sensitive
thermal paper. Draft-quality printing may be achieved
using the thermal
transfer ribbon on IBM Multi-System Paper (P/N 7034548) or
equivalent.
Printer Controls
There are three controls- A slide
potentiometer on the
left is for Density, left is light, right is dark. A two
position switch
in the middle, left is Off-Line, right is On-Line. A
button is on the right
for Line Feed. There is a blue lever on the left corner
for clamping the
guide against the roller. A paper advance wheel is on
the right.
Detach Printer
Open printer cover. Look on the left side
of the printer
at the front corner of the smoked plastic cover. Notice
the well with the
silver loop. Lift up and pivot it out. This unlatches
the left side, and
the right side is just a pivot. Twist off the slice,
pivoting it to the
right.
PRINTER CABLE (#4055):
A cabling accessory 22 inches (0.6 meter) in length with
a custom 72-pin
system-type connector attached to each end. It provides
the user the option
of operating the Printer (#4010) immediately adjacent to
(that is, physically
detached from) the system unit, to provide flexibility
of placement for
ease-of-use and visibility.Mad
Max has one of these,
looks like THIS.
SERIAL/PARALLEL
ADAPTER (#4015):
The adapter provides an RS-232C asynchronous
communications
interface and a parallel printer interface that are
compatible with the
IBM Personal Computer Asynchronous Communications Adapter
and the IBM Personal
Computer Parallel Printer Adapter. Looks like
THIS.

It allows the user the option of
connecting a separate
CRT display to the system. The optional 5144 PC
Convertible Monochrome
Display or 5145 PC Convertible Color Display may be
attached via this adapter.
Through the use of optional connectors or cables, the
CRT Display Adapter
(#4020) also allows the attachment of the IBM 4863 PCjr
Color Display,
IBM 5153 Color Display, or a standard television
set.
Don Hills saves my bacon by saying:
The RCA jack is composite video out. The 18
pin header
is the CGA output for the monitors (mono and colour)
sold specifically
for the Convertible. They came with an optional stand
that held the monitor
just above the system unit, in the airspace created by
unclipping the LCD
display after opening the unit. The connector is the
same as that used
on the PCjr. There is an optional 6 inch long cable with
a plug to fit
the header on one end and a 9 pin CGA connector on the
other for connecting
a standard CGA monitor.
The 5 pin header is for an optional RF
modulator, again
like the PCjr one, for displaying the composite video on
a stndard TV set
without video in socket.
LCD Display
Each system unit is
furnished
with a detachable LCD. When latched closed, it forms the
cover for the
keyboard and diskette drives. The LCD is attached via a
"quick disconnect"
connector, so that the 5140 System Unit may be placed
below an optional
5144 PC Convertible Mono Display or 5145 Color Display.
80x25 text, 640x200
and 320x200 graphics 16K RAM display buffer,
8KB LCD font RAM
From Don Hills
The original systems had a first generation
LCD display-
my first machine came with one. These were grey and low
contrast. They
were upgraded with a supertwist LCD (sort of green/navy
blue) that had
much better contrast. My first machine came bundled with
this upgrade which
I performed myself. I only ever saw one system with the
backlit LCD. It
used an electroluminescent panel rather than a
fluorescent tube and diffuser.
They fell out of favour because they couldn't produce as
much light as
a tube.
The backlit LCD was OK in very poor light
conditions, but in
normal room lighting or sunlight you were much better
off with the standard
supertwist. I used to sit up in bed writing code (DOS
device drivers in
ASM, for example) with my machine. I had a small lamp
mounted on the wall
behind me that shone at just the right angle for good
visibility. The display
characters were large, and it was easy to load different
fonts into the
font memory until you found one you liked.
Backlit LCD
Backlit LCD has internal illumination,
which means it
can be used in low-light conditions. Battery life
is dependent on
the setting of the brightness control. The Backlit
LCD works on all
PC Convertible models by plugging it into the LCD
assembly, in place of
the current screen, and installing the new power
supply. A new power
supply is packaged with the Backlit LCD Option
Kit.
Use of the Backlit LCD with the
illumination feature turned
all the way up could shorten battery life to between 2.5
and 4.0hours.
The brighter the intensity the shorter the battery
life.Battery life is
also dependent on the application used and the amount of
I/O activity.
The Light Panel for the Backlit LCD has in excess of
1500 hours of illumination
time. Replacement light panels (81X8536) are available
as a maintenance
part.
INTERNAL MODEM (#4025):
Provides the user the capability to communicate with other
compatible
units/systems over existing telephone lines. It uses
modulation methods
and frequency tolerances equivalent to either Bell 212A
(1,200 baud) in
high-speed mode or Bell 103A (300 baud) in low-speed mode.
It is offered
as a complete assembly consisting of two cards connected
by a cable. The
entire assembly is installed in the system unit.
