PCMCIA Port Identity
Your Tadpole has two PCMCIA slots. Slot 1 is nearest the keyboard top,
and Slot 0 (zero) is furthest from the keyboard top.
PCMCIA Port
Flap
The PCMCIA port's flap can be removed for convenience.
This is useful if you wish to install an interface card, such as a modem,
which uses a connecting cable. The door is retained by clips at its hinges.
Remove PCMCIA port flap:
1. Open the door to an angle of about 60 degrees.
2. Pull firmly to release the hinge pins from the hinge clips.
Replace PCMCIA port flap:
1. Locate the hinge pins so that they both touch the hinge clips, with
the door at an angle of about 60 degrees.
2. Apply a steady but firm pressure until the hinge pins clip into
place under the springs.
Install
/ Remove Memory
Preparing to Remove the SIMMs
1. Ensure that your Tadpole is powered off by carrying out a system
shutdown, as described in "Powering off using a system shutdown" and is
not connected to an external power supply unit.
2. Close lid and place your computer upside down on a level surface.
3. Remove battery cover and battery.
4. Placing the forefinger of the left hand on the L symbol and the
forefinger of the right hand on the R symbol on the SIMM cover, gently
pull the SIMM cover toward yourself with your forefingers until the rearmost
row of clips disengage from the base casting. Then, with your thumbs, press
the cover towards the rear of the unit until the clips (normally) located
beneath the battery disengage.
Removing the SIMMs
1 Gently press the latches of the first SIMM socket outward until the
SIMM pops up (see views A and B). This frees the SIMM for removal.
3. Remove the SIMM.
4. Repeat for the second SIMM.
Installing SIMMs
1. Hold the SIMM with contact edge points away from you and the cut-out
edge on the right. Place the SIMM's contact edge against the SIMM connector
(see views C and D).
2. With contacts in position, gently press the SIMM downwards until
latches click into place.
3. Repeat steps 3 and 4 with the second SIMM.
4. Replace the SIMM cover.
5. Replace the battery and battery cover.
Checking the SIMMs (pulled from SPARCbook, unk)
1. Power your N40 on.
2. When the OpenBoot greeting is displayed, press Pause-A.
3. Check that new memory capacity is correctly reported on display.
4. Power off by pressing Pause-O.
INTERNAL BATTERY PACK (10xAA NiMh
1,100mAh) (#7090)
This is a rechargeable battery pack, made up of 10 AA-sized
Nickel Metal Hydride (NiMH) cells, that fits inside the main unit covers
(in a compartment under the keyboard). It is also chargeable if fitted
into the Internal Battery Pack Storage charger. Energy capacity is
approximately 1,100mAh. The battery life under normal operation is
approximately 45 minutes. incorporating temperature sensor and charge mechanism
Sunder wrote:
From what I understand, there is a thermoresistor in there,
so when you crack it open, be careful not to rip it out. Just replace
all ten cells with new NiMH AA's and you should be good. You can
probably even go to the higher capacity NiMH's that are 1800ma from say
cyberguys.com
External Battery Pack and Cable
(10xD NiCd 5700mAh) (#7091)
A rechargeable battery pack, that is attached externally
to the main unit. It can be connected either by a snap-on connection of
the battery pack unit to the rear of the system, or it can be connected
via cable, with the battery pack free-standing (not attached). It is made
up of 10 D-sized Nickel Cadmium (NiCd) cells, and the charger for the battery
pack with a capacity of approximately 5700mAh. The battery life with typical
use scenarios is greater than 4 hours.
Power Supply: External 60W, system input voltage
12V, 4.6A
Interesting box, made by Tadpole of UK.
Unixguys sighs:
Yup .... but after IBM pulled the plug on Tadpole and decided to build
their own risc laptop (820-60 later discontinued) Tadpole sent all the
tooling back to IBM and threw everything else out. The only thing on their
site are a few patches. There was a lot of bad blood over this exersize.
During the CeBIT I saw the N40 RISC-notebook from IBM with the Power-Chip
inside. The machine had WABI as a beta installed and you could see the
Windows Programmanager sitting on the AIX Motif desktop (showing a GPF
;)) .
The display was a normal 640*480 TFT(?) LCD screen. There was some sort
of harware-zoom, you could magnify parts of the virtual 1280*1024 desktop
and move it around on the display.
The machine could be equipped with 64MB of RAM and has a 300 MB harddisk.
After the AIX and the paging space is gone you should have approx. 100MB
free on the disk. Machine owns two PCMCIA-slots.
AIX is a special version, capable to do a freeze-state, everything dumps
on disk, machine stops, all in 30 sec, and back on in 30 sec where you
left.
Machine runs 45 min (yes sir, minutes!) with internal batterypack, runs
2 hours with external. No Powermanagement system included. They had a normal
looking mce connected to control the X11, no signs of a trackball or other
more travel oriented input device.

: I don't know for certain, but I suspect you could simply hookup a
SCSI Zip, and then reformat the disk with a JFS. (Probably
no special drivers are needed to do that.)
Several months ago I experimented hooking up a ZIP drive to an N40 portable
-- a PowerPC CPU running a mutation of AIX 3.2.5 with a VERY small hard
drive and insufficient memory. I grabbed the SCSI ZIP drive from
my Linux machine, a Macintosh Powerbook SCSI cable, hooked it all up, and
booted. I might've had to kick smitty into acknowledging the new
SCSI device, but I don't remember. In any event, the device was seen,
and I was able to throw JFS onto a ZIP cartridge with no trouble.
Now, if a mutation of AIX 3.2.5 on a VERY suboptimal portable can deal
with a ZIP drive, it's probably safe to assume that larger systems can
deal with it. Then again, weirder things have happened with IBM products...

N40 FAQ by Tadpole-Cycle
Power 7007 off: The Power switch is only configured to power on the
system (default). To save the current session for resume at the next
power on, use the 0 key sequence. To shutdown cleanly use the AIX
shutdown command (ie; shutdown -F).
What do the status codes in the LCD display panel mean?
Answer: Most
status codes are exactly the same as the RISC/6000 LED status/progress
codes detailed in the AIX 3.2.5 Messages Guide and Reference except for
the counting codes displayed during a SAVE operation; these number represent
the number of MBs saved.
Boot off a cdrom or bootable mksysb tape
Since there is no mode key switch like on the RISC/6000, the
function was built into firmware. At power on, use the k key sequence as
soon as the blue IBM logo appears.
After a few seconds, the maintenance Main Menu will
appear:
Select option 7 (Soft Key Switch Settings)
Select option 3 (Service)
Enter "99" to return to the Main Menu then select option
10 (exit and boot)
The system will boot from the first available scsi
device other that the internal hard disk.
How do I tell what the hardware configuration is?
Select option #4 (Show Hardware Configuration) from Main Menu (as above)
Flashing "888" on LCD status panel as soon as the N40 is powered
on.
Memory SIMM(s) loose or unseated. Reseat memory SIMM(s)
I get an error status code and can't boot, how do I perform maintenance
like fsck, etc.? The N40 can't boot off standard Service Boot diskettes.
Boot from the AIX 3.2.5 for N40 cdrom in Service
mode (as described above) then Select option #4 (Open Limited Maintenance
Shell)
At the # prompt, enter "getrootfs hdisk0 sh" Perform necessary
maintenance.
N40 keeps prompting for "Security Key" at boot
up.
A disk security key can be entered from NCE
If the security key has been forgotten, then the customer
must call Tadpole-Cycle Customer Service to verify registered ownership
and generate a maintenance key to bypass the lost security key.
Configure Appletalk interface LTALK lpp
not loaded in default load.
Follow instructions in /usr/lpp/bin/README.N40 about how to
install and configure the port.
Is ISDN supported? It's mentioned in /usr/lpp/BOS/README.
Never fully implemented. Not supported. But look HERE
Can I update to AIX version 4.1?
No update is available.
The latest patches to AIX 3.2.5 for N40, version A.2, are available
HERE
How do I tell if NCE is installed? Do "lslpp -h NCE.user.obj". If present,
this lpp will show the current release and status.
When you bring up NCE Display panel, no display types listed.
Cause: The /etc/fbconfigurations file can get zero'd out when
written back to disk from memory. Get
fbconfigurations.N40
(DEAD) then make a copy just in case.
Why won't NCE Connect or Location dial out the internal modem?
TTY1 is not defined (see AIX 3.2.5 for N40 Release Notes).
Use "smit tty" then "Add a TTY" to define tty0 on sa0 and tty1 on sa1
(Internal Modem).
Modem communications programs other than SLIP are Cu and
ate. They are available from the installation cdrom (not preloaded).
Use "smit installp / Install software products..." to
install either or both:
bosext1.uucp.obj (provides cu and uucp) bosext2.ate.obj (provides
ate)
How can I tell if the save logical volume is active?
Use the "saveon -l" command.
Increase the size of save logical volume after
adding more memory
Use the following commands to remove the savelv:
saveon -o
mksaveres -i -d /dev/hdisk0
sysdumpdev -p /dev/sysdumpnull
rmlv -f savelv
Do this to recreate the save logical volume at correct size:
mksavelv
mksaveres -s /dev/hdisk0
saveon -d /dev/hdisk0
sysdumpdev (or reboot)
Help screen were not implemented in the A.1 and A.2 cd releases.
Help screens added to the A2plus updates are available. Download the latest
nce.tpn0002 and nce.tpn0003.

After I installed the patch, the N40 does not boot. It: only displays 299
at the LCD-Display. What to do know? IBM told me to: boot from CD-ROM with
any Standard SCSI-Drive. I tried with a: HP-SCSI-Drive, but this doesn't
seem to work.
Display 299 indicates "IPL ROM passed control to loaded code. The system
halts if control transfer was not successful. Report the problem to hardware
service as SRN 101-299 ..."
What I suggest is to try and get into the "Configuration and Diagnostics"
menu. You can get there by interrupting the startup process by pressing
Pause+K from the keyboard. At least if you can get there, you could examine/modify
your boot device, perform built-in diags etc.
I hope this helps.
