Background

This is a small Handheld Terminal Unit (HTU).  It's part of the military Common Hardware Software program.  The idea being that computers can be customized by what software they run.  This is a 486 class CPU with 32 MB ram that uses PCMCIA for all the disks thus allowing for removable disks, probably as a security measure.   The DRS Technoligies Scorpion is the 2008 version.

These showed up on eBay for under $100.  Looking for any info on it.  Let me know.

There are two PCMCIA slots on the other side, one about 3.5" deep and the other about 5.5" deep.
Is there a way to load Windows in a PCMCIA card so the computer will boot from it?
There is a small PCMCIA internal hard drive (not in the externally accessible slots).
screen size is 6 1/8" wide by 4 1/2" high.
When an external monitor is used there is color info.  Don't yet know about the PSG-9 LCD.

Note the adjustments for LCD brightness and contrast work on the LCD hardware, not the external monitor.

5 May 2008 - I think the reason these computers were surplused is because they have an internal BIOS battery.  That it's soldered to the mother board is even worse.  And that it's not available is much worse.  The cost to the government to have a qualified person open the computer and install the BIOS battery would be staggering.  Afte the battery was installed then  the BIOS settings need to be restored.  Note when the BIOS battery goes bad you loose the use of the internal hard drive.
Dead BIOS Battery
The problem is the BIOS battery died.  That prevents access to the internal hard drive which contains DOS. 
  • The battery is no longer available.
  • The Cylinders, Heads and Sectors/Track (CHS) is unknown.

 12 May 2008 - I've received an email indicating that the switch shown in Fig 20  is to zeroize the BIOS.  When I found the switch I cycled it a few times to be sure the contacts were not oxidized and don't see how it could change anything since the BIOS battery is dead.  But now the BIOS does not run at power up. 
Also that J17, the 4 pin connector you can see inside the external PCMCIA access hole is for loading the BIOS.  If you know more please tell me.

BIOS Updating & the Switch & J17

"The switch on most motherboards "to zeroize the BIOS" is usually there to allow a new BIOS image to be loaded into the BIOS EPROM. This is usually done off of a floppy with an appropriate loader utility and the new BIOS image on the floppy. Typical sequence is to power down, insert and boot off of the BIOS imaging floppy, run the utility on the floppy and load the new (presumably updated) BIOS into the EPROM; then power down, reset the switch jumper/back to normal, and power up and boot with the new BIOS intact. I would expect the four pin connector to be some form of serial interface (not necessarily RS-232 nor RS-449, possibly just TTL levels) used to load the EPROM on board from some external computer.

I've not seen a true "zeroizing" BIOS switch/jumper, and with most commercial motherboards, the switch only enables BIOS loading, it actually doesn't zero out the old BIOS automatically.

This implies that you would need the utility, the BIOS image, and the interface spec to successfully update the BIOS."
Hope this is of some help.

Geoff

The PSG-9 uses a BA-5600  which has an 8.4V has center contact NEGATIVE outside contacts (half moons) are POSITIVE

& Shorter cylinder 2 D LiSO2 cells.

 >From memory:
--The unit turns on by pressing both buttons on the front panel in the upper left and right simultaneously (hold down until turn on).
--If you have a bad screen you can connect a VGA screen to its 15 pin subminiature D connector.
--The small metal circular connectors are "Lemo" connectors (Brooke comment: I don't think so, Lemo connectors use a push on, pull off mechanism, not threads)
--It is essentially a slow PC architecture, the cardbus (PCMCIA) system is standard, but the boot setup is not, and can be configured by going into the BIOS setup (usual) (I don't remember the key sequence to get there)
--As a PC with only PCMCIA card disks (which includes the internal hard disk, by the way--only accessible by taking the entire thing apart) you can boot off of an insertable disk by first reconfiguring the BIOS to select it to boot. The PCMCIA insertable disk must be loaded elsewhere: find a laptop with a PCMCIA slot, and a floppy and/or a CD. Get a 1 or more GB PCMCIA drive or compact flash with PCMCIA adapter, load in your new found laptop, and put a bootable DOS image of system on the PCMCIA disk; then copy your OS of choice, that is likely the INSTALLATION CD, onto the PCMCIA disk. Insert the PCMCIA disk into the PSG-9, boot DOS or equivalent, and then start your OS installation. This needs to be done so your OS installer can recognize the internal configuration of the PSG-9 hardware.

If you can't boot DOS you have other problems-- either hardware or BIOS settings, or you didn't create a bootable PCMCIA disk.

Hope this helps.

Inside

There may be a way to either find or add an external power connection to the existing connector pins.  So opening up is the next step.

When the lid is removed what's under it is the LCD. 
A glass panel comes off with the lid.
To the right of the screen is the inverter transformer that's part of the CCFL backlighting.
This is looking up from inside when the keyboard is folded flat.

 I didn't notice any alien beings when taking these photo, but Fig 7 seems to show the reflection of one looking over my shoulder?  Fig 10 is the most interesting since there's access to the bottom of the battery compartment.  More later after the Fluke 87 does it's thing.

To remove the motherboard assembly after the top and connector assemblies have been removed, just lift it out.
It is possible to removve the motherboard addembly with the connector assembly installed, the ribbon cables that connect to the connectors are long enough.

Black wire has a crimped ring tongue terminal with a 2-56 screw holding it.
The BIOS setting back up battery measures 0 volts.  The ICs have 1994 and 1995 date codes
so it's (2008 - 1995) about 13 years old.  It's an ER10/28 3.6 Volt 1/2 length AAA.  I doubt a AA
diameter will fit this corner that's beside the main battery compartment.
The smaller board with one of the flex circuits connected is the power supply.
There's another same size board under it.
Note the black feet on the back side to protect the face of the LCD screen when it's set down.
The small white connector on the main board near the upper left corner is probably the audio
like would be connected to a CD player.

Power

The battery is the BA-5600/U which is a negative center contact stick with three LiSO2 cells or about 9 volts.
Saft data sheet for BA-5600/U, shows it's for the AN/PSC-2.

In addition to the dumb BA-5600 there are apparently some smart battery options for this computer.

BB-741/GYC, BT70341, (it's not clear what these numbers are: 420324-100, 842558-1).
In addition to the center negative contact and two half moon positive contacts there are four additional contacts:

A = CHRGPATH
B = MOD
C = +12
D = BATINFO
The BB-2600 (NSN 6140-01-467-5853, BT-70443) is a Li-Ion rechargeable. 
It has been replaced by the BB-2600A/U (NSN 6140-01-490-4311, BT-70743)
It does not have the ABCD smart battery contacts.  The gas gauge and charging contacts are on the cap end with the regular discharge contacts on the other end.


Fig 11 Battery Socket
PSG-9 Contacts that
          mate with batteryLooking into the battery compartment.

The center contact is negative and is connected to the chassis, i.e. is ground and shows up on the metal case and a lot of places on the connectors.
One or more of the 4 contacts at the bottom will contact the half moon positive terminals no matter at what rotation a dumb battery is installed.

The four contacts at the top in a square pattern are recessed below the face and so will not be touched by a dumb battery. When a smart battery is installed it needs to be rotated so the projection matches the pocket.

Just to the left of this photo is the wall that's shown above in Fig 2 on the top.  The three dark green square shapes are thin panels that will rupture if the battery vents or explodes.  Just inside each of them the metal frame has eight holes that hopefully will allow gas to pass but stop large chunks from flying out.  There are some dead lined BA-5600 batteries that have exploded and for them the self discharge switch should not be pressed.

This is the same system used on laptop computers where the gas gauge has a serial port to report the batteries state of charge.  So I suspect the cells are Li-Ion.  If the battery can be charged while in the PSG-9 then there must be an external power input connector, WHERE IS THE EXTERNAL POWER INPUT? let me know
This may be the first military battery to have a smart gas gauge.  Many of them have LCD bar graph indicator gas gauges.

The M455-1/GRC-206 Power Source has an 8 Volt output for powering either this device or similar 8 volt computer type equipment.

Backup Battery

There is a 3.6 Volt  1/2 size AAA (9.7 mm dia x 25 mm long)  lithium backup battery with leads soldered to the motherboard.  See Fig 16.  This one is completely dead.  It's required if you want the BIOS settings to be remembered.  And that's required to set the hard drive Cylinders, Heads and Sectors.

J2 External Power Connector

Although J2 is in the same connector family as J3 they are keyed differently so you can not plug the external power cable (J2) into the keyboard/mouse jack (J3).
See Connectors below for photo of J2.

Start Up

8 March 2008 - With 9 volts applied to the battery terminals (soldered red wire to one of the four battery socket pins after removing the connector sub assembly, Fig 10).  To the upper right and left of the LCD are a couple of momentary rocker switches (Fig 2)that have two bars at the top and one bar at the bottom.   When both of the bottom bars are pressed and held the computer boots up:
The green POWER LED turns on and the other LEDs do a dance. The LCD is showing a PhoenixBIOS DOS boot release 1.13.  At first I thought the LCD was dead, but when looking at a steep angle from below you can see the text.  Optimum viewing angle is 45 degrees below square on.  But it needs a contrast adjustment.

 Should the Fn+F4 and Fn+F5 controls work in the PhoenixBIOS or is this part of some higher level language (Fig 4 Keyboard)?
Note:  on the keyboard there is a white box surrounding each key.  Those icons without a box are just labels above the function keys.  The upper right key toggles the keyboard illumination on and off.  But to see the screen the desk lamp is supplying the light.

Maybe the CCFL lamp is bad????

3) is there any mouse or touch screen support?
4) is this a special BIOS that has built-in PCMCIA support?  My WIN XP BIOS does not.

CCFL Back Light

After the boot process the screed went dark.  I thought the CCFL power supply was defective,hence this paragraph. 

10 Mar 2008 - This is normal operation.  When using J2 to provide external DC power the screen looks normal during the BIOS part of the boot, then switches to the poor contrast mode.  That may be because of the contents of the existing hard drive.  For example the hard drive software may configure the screen improperly.

The lamp is 3 mm dia x 128 mm long.

The design is based on Linear Technologies LT1172 100kHz, 5A, 2.5A and 1.25A High Efficiency Switching Regulators and very close to  App Note 49 Fig 2 & D-1.
The full primary of the transformer has a data sheet resistance of 0.19 Ohms (center tap half that) and the feedback windings are 0.084 Ohms each so it's difficult to make resistance measurements.  Instead of the half bridge transistors specified in the app note some Zetex parts were used.  The Zetex parts are specified to have ten times lower Vces.

2783384  ELECTRICAL INVERTER CIRCUITS, R.L. Bright & G.H. Royer, Feb 26 1957, 331/113A ; 290/4R; 307/401; 331/181; 363/133 - magnetic saturation of the transformer is a key parameter.

The LT1172 (U1) has it's Vin pin wired to connector J1 pin 3 and not to the +8 volt supply, maybe as a way to disable the LCD?
To check the inverter the switching output pin of  U1 or the emitter of either Q1 or Q2 can be grounded.  This turns on the CCFL even when the lid is has been removed.   When testing after starting the computer the lid can be disconnected and the computer continues to run.

I've tried pulling J1 pins 3, 4 & 5 up and down one at a time (I don't have enough hands to do more, and no single pin will turn on the CCFL.  Note the Royer patent shows that a couple of transistors, a special transformer and a source of DC are all that's needed to make an inverter.  The 1172 is there to regulate the current and control the brightness, i.e. lamp current.

Operating System

The short bars above the starting longer bars are the navigation buttons.  The screen is VGA color, so some flavor of Windows should run.
Also in a military environment a mouse does not make sense.  Win XP requires a minimum of 256 MB of RAM and so is way too big.
WIN 3.1 would fit and WIN 95 or WIN 98 might fit.
DOS 6.n makes the most sense.

14 March 2008 - waiting for PCMCIA hard drive.
4 April 2008 - the PCMCIA hard drives have been here for some time.  But when I tried to put them into my laptop - no go.
The hard drives are Type III, i.e. 10 mm high and would not fit.  So eBay had a PCMCIA to PCI adapter advertised with the words "works with Type I, II or III cards and the photo showed a tall slot, BUT when it came the slot was about 6 mm nowhere near 10 mm.  Well after returning it today received an email refunding my purchase.  I have a feeling that most of these adapters advertised as Type I, II, III are only good for the 5 mm cards unless there are explicit words stating otherwise.

PCMCIA Hard Drive


Fig 24 Viper 170 MB Drive
PCMCIA Hard Drive 10 mm high
Found on eBay and think it's the same type, only half the capacity, as the drives that were used in the PSG-9.
This is a 170 MB dirve and they were 340 MB.
This probably is a 16 bit drive, not a 32 bit.
It's twice the height of most PCMCIA cards, Type III, not Type I or II.

PCMCIA to PCI adapter card to preload hard drive


Fig 25 Viper Drive in PCI slot adapter.
PCMCIA (PC Card) adapter to PCI bus
This adapter has the proper large opening so that the 10 mm high hard drive PCMCIA card can fit throught the mounting bracket.

Next w'll see if the adapter works and if the drive works.
It did NOT work.  I haven't been able to format the Viper as a bootable drive.  You can read it, format it, write and read files, but NOT make it boot DOS.

14 Apr 2008 - spent most of yesterday trying to make the drive bootable.  It's relativity easy to make a bootable floppy or CD-ROM with DOS 6.22 but not a hard drive.
The WIN XP computer hard drive is NTFS formatted so can not be read by DOS.  A fix is probably to get a new drive and format it as FAT and install WIN 98 (which runs over DOS).
The software packages that make a media bootable are very specific about working on a floppy or CD and exclude a hard drive for the options list.
After booting a floppy and running DOS 6.22 the PCMCIA card is NOT a valid drive.  Either /or/ both the BIOS and OS need PCMCIA drivers added.
The big chip on the adapter card has "1410" in what's probably the part number.  TI made a 1410 and 1420 IC for PCMCIA applications so this is probably a clone of that.
So drivers for the TI 1410 may work.  Tried drivers that displayed as DOS booted:

The signals used for an IDE Hard Drives and for PCMCIA (PC Card) and for Compact Flash are all the same.  That makes is easy to adapt from one to the other.
18 April 2008 - have adapter on order that holds PCMCIA drive and has IDE connector. 
This should allow a very simple format and make system disk on the PCMCIA drive.

What is the J2 Connector?

PSG-9 J2 External Power Connector. WHAT IS IT?Fig 33 J2 Connector
The connector with the cap off is J2 used for external DC power.  It has 7 terminals (hard to say if they are male, female or both). 

The mating plug will have a body diameter of about 0.216" and 3 projecting lugs.
What is this Connector?

The three pins  (top row left, middle row left and center) are the ground connections.
The bottom row two pins are the +8 Volt connection.

What connector family and plug to make external power cable?
J3 just to the right of J2 has different keying, see Fig 3 Connector Assembly above.

William Perry has found a LEMO connector that has the correct insert, but the connector does NOT mate, only the insert.
PSG-9 J2 insert, not connector PSG-9 LEMO insert, not connector
April Note that this is the correct insert, but NOT the correct connector.  The barrel O.D. of 6.96mm is larger than the I.D. of J2 so will not fit.
I'm looking into using the insert to make a plug that would mate to J2 (or J3).
If you are interested let me know.April 2009

Fig 32 External Power Wire


PSG-9 Back of J2 Hot Wire22 Mar 2008 - This shows the hot wire mod to get power to J2 until the proper connector is located.  A couple of tie wraps to take any strain off the solder only joint.  With this connection you can see the BIOS boot then the LCD goes into invisible mode.


I started to use my laptop to load a PCMCIA hard drive, but the laptop only accepts the Type I cards (5 mm) and the hard drive is a little over 10 mm high.  A PCI card for the desktop  is on order.
Just above the second bottom philips head screw from the right there's a SMT version of a TO-220 package that contains a 340 power Schottky diode  with it's anode connected to the same terminal as the red wire and it's cathode connected to the big connector just above it.  The 8 lead IC just to the right and up from the 340 may be a power transistor.   All four top pins are connected to the battery positive pin and the lower left three pins are connected to the same row of pins on the big connector as the BD340 diode.  There's a SOT-23 FET just to the left of the BD340 that connects to the lower right pin on the 8 lead package.  These parts form the selection circuit that uses the external power as a primary supply and if it fails switches over to the battery.

Modem Protocols

The internal modem supports the Ground/Vehicle Laser Locator Designator (G/VLLD) IAW MIS 34269F over a high speed synchronous data port.

STANAG 4202 Transmission Characteristics for Data Exchange between Land Tactical Data Processing Equipment over Single Channel Radio Links
Applies to PRC-77, PRC-126, SINCGARS (Annex A), WD1 Wireline, WF-16 Wireline.
MIL-STD-188-110A Interoperability and Performance Standards for Data Modems
Applies to VRC-12, KY-57
ACCS-A3-407-008C Interface Specification for the Army Data Distribution System (ADDS) Interface
Applies to EPLRS

This seems strange.  I would expect the PRC-77 and VRC-12 to have the same capability as far as data is concerned, but not the PRC-126 since there's no mil std connector that gives acess to the wide band capability, it can only be used with the KYV-2/SVM-68.  All SINCGARS radios have a number of data modes and so might be in multiple catagories.

Reference

IPADS

The M111 Improved Position andAzimuth Determining System (IPADS) is a High Mobility Multipurpose Wheeled Vehicle (HMMWV)-mounted, inertial navigation surveying system, which will be used by artillery survey parties as a secure, all-weather, day-night means for rapidly extending survey control to satisfy the demands of mobile weapons systems.  IPADS, which does not rely on Global Positioning System (GPS), accurately aligns GPS-aided, self-locating firing elements on a common survey grid, enabling these firing elements to mass fires.  IPADS will provide a highly mobile and accurate means of performing artillery survey.  IPADS will determine location coordinates, altitude in meters, direction in millimeters (typo?) ,and will be capable of rapid and accurate self-alignment utilizing ring-laser gyros and accelerometers.  The IPADS will replace the currently fielded AN/USQ-70 Position and Azimuth Determining System (PADS) in all Marine Corps artillery units.

CA-5033/UYC Printer

The same Canidian eBay seller that was selling the PSG-9 also had this printer.  Maybe they are related and manbe not?

It's 7 x 7 x 5 inches and the roll paper is 4 1/4" wide and I'm sure it's dot matrix to support both text and graphics.

Controls and Indicators

On the front there is a combined ON-OFF switch that's also a circuit breaker.  When switched on with a battery installed the LEDs flicker and go off and the paper feeds.
LEDs for:
ON LINE
POWER
FAULT
LOW BTY
Two push buttons:
TEST - prints a test pattern
LF - Feeds a line of paper
When LF is pressed and held and TEST is also pressed (BRIGHT) the POWER ON LED brightenes and it seems continionous paper is fed.  That may be a problem or may be related to not having anything connected to the data input.

Connectors

On the back there are two connectors and a tapped hole for a ground marked E1 GND.
Circular bayonet locking.

J1 POWER

MS3470W14-5P
5 male pins in a "W" shape. 
Pins marked A, B, C, D, E & F
[ cap MS3181-14CA]

The J1 POWER connector has a low diode drop from J1-A to battery pin 5 and from J1-C to battery pin 5.  Battery pin 5 is the "A" side positive terminal.
J1-B connects to J1-D and these connect to battery pin 3.  Battery pin 3 is connected to battery pin 1 ("B" side minus) only on rechargable batteries and so is a selective way of charging only rechargable batteries and not charging primary batteries like the BA-5590/U.  Battery pin 2 is jumpered to pin 4 so the battery is being used as a 24 volt (30 V full charge/fresh to 10 volt dead).

29 March 2008 - my day one guess is that B & D are ground and A & C are +28 VDC.

J2 DATA

MS3470W10-6P
6 male pins.
Pins marked A, B, C, D, E & F
[cap MS3181-10CA]

There are 6 wires from the back of J2 they are (in pin number order) Wht, Blk, Wht, Blk, Wht, Blk.
Pin 1 on PCB is J2-A and Pin 6 on the PCB is J2-F

Battery

The internal battery is one of the BA-5590 family.

Fig 34 Printer Battery Compartment

CA-5033/UYC Printer Sliding BA-5590 Battery
                  Door

On the left side there are two screws that can be backed out a few turns then the battery door slides to the left (no need to remove the screws).

A BA-5590 battery is connected to the cable plug and the plug end fed in first.  My 5590BA will also work.
I have the cover off which had three seals that were already broken.  Front is to the right of this photo.  The PCB to the right is the printer driver and the PCB near the battery is the power supply.   There are 5 wires going to the battery so it may support rechargable batteries like the BB-390, BB-590, BB2590, etc. when external power is used.

A minimal connection would be pins 2, 3 and 5.  The next most common would include CTS/RTS so would have pins 2, 3, 5, 7 & 8 which is 5 pins and so may be what the CA-5033 uses.
The HP LaserJet has the following voltages for those 5 pins: -6.4, 0, 0, 0, +6.9.

The A-C voltage of almost 19 seems too high so the ground pin is not A or C.
The data is symmetrical about the diagonal.
Looking for rows that have three zeros and one each + and one each - voltage yeilds:
B, E or F as possible ground pins.
