 ==== Hard disk ====
-Toshiba T3200SX comes with either a 40 MB or a 80 MB hard drive. The T3200SX/120 was a later upgrade model, and comes with a 120 MB hard disk. The system has a standard IDE interface to connect to the supplied Conner CP hard disk. Most Toshiba T3200SX(C) computers are BIOS locked to specific hard disk part numbers, so you cannot upgrade it easily. If you try using a different hard disk, the computer will most likely refuse to detect and use the hard disk, unless it identifies itself with the computer with a part number starting with the letters "CP" which stands for Conner Peripherals. Old (003C) BIOSes will allow you to use any hard drive, but will still use the disk settings for the hard drives that were originally supplied with the system. In this case, you can override the settings programmatically, with Anydrive, found under [[Files and Resources]].
+Toshiba T3200SX comes with either a 40 MB or a 80 MB hard drive. As far as I understand, there was also a T3200SX/120 which was a upgraded model, and comes with a 120 MB hard disk. The system has a standard IDE interface to connect to the supplied Conner CP hard disk.

+This system can be expanded with an 8-bit and 16-bit ISA expansion cards. Hence, you can purchase an XT-IDE adapter to add a hard drive, such as the XT-CF-MINI or XT-CF-Lite card to add a Compact Flash card as a hard drive. They usually run for $40-$60. You can find them on eBay or [[https://www.texelec.com/|Texelec]].
+Another option is to purchase an XT-IDE adapter for the Toshiba proprietary expansion slot. There is a maker on eBay that sells Toshiba type expansion cards with XT-IDE to allow many different types of IDE and CF cards to be used on the portable computer.
+Please see the following link for the sales article. [[https://www.ebay.com/sch/i.html?_nkw=3inoneder|3inONEder: Toshiba Portables]]
-If you're lucky, your computer has the older BIOS, and will ignore the part number and will let you boot from any IDE drive as long as you manually override the BIOS settings in software using ANYDRIVE or any other BIOS overlay software, like OnTrack. However, if you have a newer BIOS, the computer will not detect the drive unless it's made by Conner (it's IDE identifier string must start with the letters "CP").
+==== Audio and ethernet ====
+The same adapter that allows you to use the Toshiba proprietary slot connector for XT-IDE and custom hard disks also optionally allows to add audio (Adlib) and ethernet support (partially NE2000 compatible).

+===== Frequently Asked Questions =====
 **Q: What is the PRN-A-B Switch on the side?**\\
 **A:** Toshiba offered an external 360Kb disk drive as an option. This plugs in to the parallel port connector but is not a parallel device. Setting the switch to PRN enables the printer port, setting it to A tells the machine there is an external disk drive and you want it to be A drive. Setting it to B tells the machine there is an external disk drive and you want it to be B drive. Setting it to A would allow you to boot 360Kb boot disks.

+===== System Maintenance =====
+==== BIOS clock battery replacement ====
+The BIOS battery header is located on the system board. The battery is traditionally tucked in at the back of the floppy drive. The correct voltage for the battery is 3.6V. To replace the battery,  do the following:\\ \\
+Remove the old battery by cutting the leads at the battery terminals, and get a replacement battery ER14505 3.6V lithium, sold new at eBay and other sources. You will also need a 1x AA battery holder. If you cut the leads at the battery terminals, you should have been able to preserve the in line 330 ohm resistor at the negative pole and you will want to leave that in place. Solder the old battery wire to the battery holder and place it where the old battery was, right behind the floppy drive. Alternatively, you can use any 14500 3.6V lithium battery as the clock battery. In any case, your setup will look something like this:
+<code>
+[BATT +]----------[+ ER14505 -]---------.
+[BATT -]-------------[ 330R ]-----------'
+</code>
+==== Hard Disk upgrade ====
+The upgrade method depends on the BIOS version of your Toshiba portable (see below for instructions how to check the BIOS version). Most Toshiba T3200SX BIOSes are restricted to CONNER hard-drives of either 40 or 80 megabytes size (T3200SXC will be either 40 or 120 MB). On boot-up, the BIOS queries the IDE controller for hard-drives, and depending on your BIOS version, one of two things will happen:
+  - ** Older Toshiba BIOS (such as 003C) **
+    - The computer will detect any drive and just assume it's a 40 MB  disk (regardless of its actual size).
+  - ** New Toshiba BIOS (such as 003E-003I) **
+    - The computer will not boot an unsupported drive unless it is manufactured by Conner. It will assume it's a 40 MB drive (regardless of its actual size). If you have a different drive than Conner, the computer will simply refuse to boot from the hard disk. The model/part number reported to the computer must match the letters 'CP' (Conner Peripherals) for it to be detected.
+You have a couple of options:
+  - If the computer has the **older BIOS** such as the **003C**, the computer should ignore the part number and will attempt to boot the hard disk regardless, even with incorrect settings. However, since the settings are fixed, you can not use more than the amount of space specified in the BIOS, which is only 40 MB. To override the BIOS limitation and use more space on the disk, so you will need to manually correct the settings on boot using a drive overlay software which is installed on the hard disk. I have tested a program called Anydrive, and I believe Western Digital's EZ-Drive version 9.03W will work as well. Both programs can be found in the files section. Anydrive overrides the BIOS settings so you can use any size hard disk (or CF memory card with CF to IDE adapter) up to 504 MB. With EZ-Drive you can potentially use larger disks, but run the risk of disk file corruption above 4 GB.
+  - If you have the **newer BIOS**, you can do the following:
+    - Buy a BIOS ROM chip drop-in replacement. Please see my [[#Replacement BIOS ROM chips]] section for more information how to buy.
+    - Buy a compatible Conner hard-disk. The compatible part numbers are listed above.
+  - If you have an EEPROM programmer, such as the Minipro TL866, you can make your own BIOS chip and replace the problematic one by using HighTreason's excellent tutorial. Programming a compatible BIOS will allow you to boot with any hard disk, and then simply install a hard disk overlay program to override the drive parameters with correct ones. The tutorial, associated ROM images and HDD overlay programs are in the [[Files and Resources]] page.
+  - You can also buy an XT-IDE adapter, such as the XT-CF-lite from Lo-Tech. TexElec carries these in stock in the US. This will bypass the built-in IDE controller completely and replace it with a CF card. You can then set your BIOS to "No drive".
+Note: If you plan to use a drive other than what was supplied with your computer, you must use a BIOS HDD overlay program (in the [[.:files and resources]] section) to avoid data corruption.
+**Q: I upgraded the hard disk on my Toshiba, but now it refuses to boot, or doesn't detect the hard disk.**\\
+**A:** If you have verified the replacement disk is fully working, then your computer must be using a BIOS version that only detects and supports Conner hard disks. See above for details.
+==== Check the BIOS version ====
+You need to open the portable computer. Remove the four screws from the bottom front of the laptop. Open the screen lid. The keyboard should now lift up starting from the front. You may need to pry the keyboard a little. Once the keyboard is off, remove two screws at the rear of the EM shield between the keyboard and the motherboard. Remove the EM shield. You will see three chips. The one at the bottom right corner is the BIOS chip. So far I've seen 003C, 003E, 003F, 003H and 003I out in the wild. If you have a different BIOS version, please take a picture of it and send a BIOS dump over. I will be happy to host it on this site.
+==== Moving the display out of the way to access PSU, HDD, FDD ====
+After opening the laptop, you will find that getting access to other components toward the rear of the system can be tricky, especially to access the hard drive, floppy drive or the power supply unit. If your laptop has never been opened, chances are there is a metal piece fastened to the chassis that will prevent you from pulling the flat panel free as it is holding the flat panel cables down. The latch will be held on by a single screw. You will need a short Philips screw driver with preferably a 90 degree angle at the bit to unscrew the piece and release the flat panel display cable.
+{{ :toshiba_t-series_support:images:t3200sx-latch-holding-display-down.jpg?450 |}}
+If you don't have access to a small angled screw driver, you may be able to bend the latch up and out of the way to release the display cable and extend access to the back of the system.  It is risky as you may damage the display cable near the latch so please be careful. Never pull or twist on the display cable, and always support the display while it is on its side.
+To access the rear half of the system, I have found this arrangement to provide ample access.
+{{ :toshiba_t-series_support:images:t3200sx-rear-access.jpg?450 |}}
+==== Accessing the internals of the display panel ====
+The display panel front bezel is fastened by four screws. Two on the top corners of the display bezel (under rubber bumpers), and two screws under the sticker that covers the power, HDD, FDD and keyboard LEDs. The screws are close to the outer edges of the sticker, so you should be able to use a flat shimmy or a dull but flat knife to carefully separate it just enough to access the screws. You don't need to remove the whole sticker, just enough to reveal the two screws. I've done this to both my T3200SX's, and there is almost no damage if you do it right. Do not pull or bend the sticker at any time to avoid bending or damaging it. Just slip the shimmy under it and push the shimmy toward the middle so it separates.
+{{ youtube>n5VqpKXXLeQ?large }}
+In this video you can see the process. Doing it one handed while taking video, the shimmy slipped, but I hope you get the idea. Also, the tool I'm using is [[https://www.ifixit.com/products/jimmy|iFixit Jimmy]]
+Once you remove all four screws, the bezel is ready to come off. Open the display lid all the way, and pull on the bezel from the bottom. The bezel should easily separate allowing you to access the rest of the display assembly.
+{{ :toshiba_t-series_support:images:t3200sx-display-bezel-separation.jpg?450 |}}
+==== Removing the entire top cover of the computer ====
+The top cover cannot be removed until the display panel is disconnected. It can only be disconnected from the display panel itself, so you'll need to first open up, disconnect and remove the panel. To remove the panel, first follow instructions under "Accessing the internals of the display panel".
+Once you have access to the internals, remove the four corner screws holding the display panel to the back cover. Be careful removing the last two screws, as the fragile glass panel can fall off easily and be damaged. I recommend holding the panel while removing the final screw. Then disconnect the power, signal, and contrast adjustment connectors from the plasma panel assembly to remove it from the back cover.
+Once that is done, you need to remove the central plastic piece on the hinge which holds the display cables in place in order to gain enough clearance to pull the cables through. This plastic piece is held on by two screws underneath. Once done, you should be able to separate the two halves of the plastic piece and angle the piece in a way to remove it. Now there should be enough room to route the display cables through the bottom of the top half of the computer case to remove the entire top half of the case.

The switch, which is located under the cover, next to the floppy drive uses a rather low-quality plastic piece that latched with the screen hinge and is designed to detect when the lid is closed, and will cut the power to the display accordingly. It engages whenever the lid is closed, and since it is near the power supply, a plastic piece inside the switch may slowly deform over time and may get stuck inside the switch. The symptom you will see is a screen that will never seem to turn on when you open the lid, or will have a noisy picture, due to the switch stuck half-on. If you cannot repair the switch manually, the easiest workaround is to just disable it by removing the plastic piece entirely. This will make the screen then stay on regardless if the screen lid is open. Please see the gallery section for an image of the switch.
-. You can remove the old battery. Cut the leads at the battery terminals, and get a replacement battery, for example a ER14505 3.6V lithium battery, sold new at eBay and other sources. You will also need a single AA battery holder for the new battery. Depending on your computer, your old battery might have included a 330 ohm resistor in line at the negative pole and you will want to leave that in place. In most cases your setup will look something like this: \\
-''[MB + ]----------------[ + ER14505 BATT - ]--------[ 330R ]----------------[MB - ]'' \\ \\
-. Alternatively, you can replace it with a 3.0V CR2032 coin cell battery. In this case you should buy a CR2032 holder, a CR2032 lithium battery and a diode. The diode may be required to avoid charging the battery. You can measure the voltage at the motherboard to see if it has a charging voltage while the computer is powered on. If it does, use the diode. Take the old battery connector and its wires, solder the coin cell holder to the wires and solder the diode in series as such: \\
-''[MB + ]----------------[|<]--------[ + CR2032 BATT - ]------------------[MB - ]''
-You may search for CR2032 battery holders including leads using [[https://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_id=114&ipn=icep&toolid=20004&campid=5338306954&mpre=https%3A%2F%2Fwww.ebay.com%2Fsch%2Fi.html%3F_from%3DR40%26_trksid%3Dp2380057.m570.l1312.R1.TR10.TRC2.A0.H0.Xcr2032%2B.TRS2%26_nkw%3Dcr2032%2Bholder%2Bbox%26_sacat%3D0|this eBay affiliate link]]
+**SYMPTOM: The computer doesn't turn on. When I flip the switch, the power light flashes briefly and then turns off.**\\
+Out of the three T3200SX's that I own, I've noticed two of them have started exhibiting this behavior. After investigating both computers, the issue was found in the power supply, specifically some of it's capacitors. I found, that four of the capacitors were leaking electrolyte and had failed (at the time failure, they were 36 years old parts, so I can't fault them!).
-**Q: How do I upgrade the Hard Disk? **\\
+To fix this issue, you'll need to do some soldering on the power supply board. Word of caution: This is a somewhat dangerous procedure since the power supply can hold high voltages in its capacitors (while powered, over 200V DC for the plasma panel), so work on the power supply at your own risk!
-**A:** It depends on the BIOS version of your Toshiba portable (see below for instructions how to check the BIOS version). Most Toshiba T3200SX BIOSes are restricted to CONNER hard-drives of either 40 or 80 megabytes size (T3200SXC will be either 40 or 120 MB). On boot-up, the BIOS queries the IDE controller for hard-drives, and depending on your BIOS version, one of two things will happen:
-  - ** Older Toshiba BIOS (such as 003C) **
+To access the power supply, you'll need to disconnect and remove the Plasma display to get it out of the way. However, I have found an easier way that involves angling the plasma display and it's chassis top cover so that you have access, see the section under [[#system_maintenance|System Maintenance]] titled "How do I move the display out of the way". The power supply is fastened to the chassis with five screws around the power supply (one screw in the middle is longer than the other four). Remove them, and disconnect the fan cable, plasma display lid sensor and power cable from the motherboard. When you have the power supply free, you can remove it's cover and access the circuit board. Again - a friendly reminder. Be careful around the bigger capacitors. They can hold a high voltage. I would recommend at least discharging the large HV capacitors close to the AC input line. Also the silk screening on the circuit board has a warning that heatsinks on the power supply may also be electrically charged.
-    - The computer will detect any drive and just assume it's a 40 MB  disk (regardless of it's actual size).
-  - ** New Toshiba BIOS (such as 003E/003F/003I) **
-    - The computer will only detect a drive manufactured by Conner. It will assume it's a 40 MB drive (regardless of it's actual size). If you have a different drive than Conner, your computer will simply refuse to detect the hard disk. The model/part number of the disk must start with the letters 'CP' (Conner Peripherals) for it to be detected.
-You have a couple of options:
+The circuit board will be attached by two screws. After removing the screws, unplug the AC wire and the power supply fan wire, and you will be able to remove the board from the power supply case. You will see a group of four capacitors (1x 1000uf 25V, 3x 3300uF 10V) toward the middle-right hand side. Check both sides of the circuit board. If you notice electrolyte leakage on either side, you will have probably found the issue. Remove the old capacitors, clear the contamination with ethanol, or similar solvent, replace the capacitors and you should be back in business.
+<code>
+Parts list:
+: Radial capacitor, 1000uF 25V, 105'C
+: Radial capacitor, 3300uF 10V, 105'C
+: Radial capacitor, 3300uF 10V, 105'C
+: Radial capacitor, 3300uF 10V, 105'C
+</code>
+If this does not fix the issue, check the 5V and 12V pins on the motherboard if any of them have shorted to ground. If they have, you might have a shorted tantalum capacitor on the motherboard.
-  - If you have the **older BIOS**, your computer should ignore the part number and will not stop you from using any hard disk regardless of size, but the computer will only give you parameters for a 40 MB drive and the setting can't be changed. You can still boot from it, but you'll only be able to use the first 40 MB of the disk, however there is an easy workaround. You will need to download ANYDRIVE (found in the files section) or any other BIOS HDD overlay program that installs in the MBR of your hard disk, and overlays the correct hard drive parameters at startup. Anydrive overrides the BIOS settings so you can use any size hard disk up to 504 MB. You can use larger disks or even memory cards with IDE-CF or IDE-SD converters, but only 504 MB will be usable. If you know of other overlay programs that allow for larger hard disk utilization, please let me know.
-  - If you have the **newer BIOS**, you can do the following:
-    - Your Toshiba cannot boot from a upgraded Hard Disk. You CAN boot from a floppy disk, but you will not be able to use the hard disk.
-    - Buy a Conner hard-disk. The part number must start with the letters 'CP'. Then use ANYDRIVE to circumvent the BIOS hard-coded drive size parameters if needed.
-    - Replace your BIOS chip with an older BIOS.
-  - If you have a PROM programmer, flash a BIOS chip with the 3CH BIOS found in the files-section, and use ANYDRIVE to circumvent any size limitations. There is a well written BIOS re-flashing guide in the files page in the section labeled Documentation.
-  - Buy the working BIOS that allows for upgrades. I sell the 003CH hybrid BIOS upgrade for the Toshiba T3200SX for a nominal fee. You will be able to buy it from Ebay. Please let me know and I will list it for you.
-Note: If you plan to use a drive other than what was supplied with your computer, you must use a BIOS HDD overlay software to avoid data corruption.
+**Q: What is the pinout and voltages of the cable going from the power supply to the motherboard?**\\
+**A:** The connector has 8 pins, and are as follows:
+<code>
++--------+--------+--------+--------+--------+--------+--------+--------+
+|  RED   |  RED   | BLACK  | BLACK  | ORNGE  | BLACK  | BROWN  |  BLUE  |
+| +5V DC | +5V DC | Common | Common | +12V DC| Common | -5V DC | -12V DC|
++--------+--------+--------+--------+--------+--------+--------+--------+
+</code>
-**Q: I upgraded the hard disk on my Toshiba, but now it refuses to boot, or detect the hard disk.**\\
+**SYMPTOM: Plasma screen is faded or does not show shades, even with the contrast knob turned all the way up**\\
-**A:** If you have verified the replacement disk is fully working, then your computer must be using a BIOS version that only detects and supports Conner hard disks. See above for details.
+This might be an indicator that the capacitors on the display panel controller board have failed. Follow the steps under the heading "How can I access the internals of the display panel?" in the [[#system_maintenance|System Maintenance]] section to access the internals of the plasma panel.
-**Q: How do I check the BIOS version? **\\
+Once you have removed the bezel, remove the four corner screws securing the display panel to the back cover of the display. Be careful removing the last two screws, as the fragile glass panel can fall off easily and be damaged. I recommend holding the panel while removing the final screw. Then disconnect the power, signal, and contrast adjustment connectors from the plasma panel assembly to remove it from the back cover.
-**A:** You need to open the portable computer. Remove the four screws from the bottom front of the laptop. Open the screen lid. The keyboard should now lift up starting from the front. You may need to pry the keyboard a little. Once the keyboard is off, remove two screws at the rear of the EM shield between the keyboard and the motherboard. Remove the EM shield. You will see three chips. The one at the bottom right corner is the BIOS chip. So far I've seen 003C, 003E, 003F and 003I out in the wild. If you have a different BIOS version, please take a picture of it and send it over! If you have the capability to read the BIOS chip, I would appreciate a BIOS image. I will gladly host it on this site.
-**Q: I've opened the laptop, but I cannot move the flat panel display out of the way **\\
+Check the plasma controller board's capacitors for any leakage or evidence of grime. In one of my T3200SX computers I replaced the following capacitors on the board which resolved the issue. After removing the capacitors, only the 47uf 16V capacitors (C1, C9, C15) measured too low capacitance, but I went ahead and replaced all capacitors that appeared to have leaked electrolyte around them.
-**A:** The Toshiba portable computer can be tricky when you're trying to open the laptop after you've removed the keyboard, EM shield and now want to have access to the hard drive, floppy drive or other connectors. If your laptop has never been opened, chances are there is a latch that has been screwed in to the chassis that will prevent you from pulling the flat panel free so you can rotate it out of the way and access the internals. The latch will be held on by a single screw. You will need a tiny phillips head screw driver with a 90 degree angle at the bit to unscrew the latch and release the flat panel display.
-If you don't have access to a small angled screw driver, you may be able to bend the latch out of the way to release the display cable. It is risky, and you wouldn't want to do it unless you there is no other way. You may damage the display cable near the latch so please be careful. I've included a picture of the latch in the image gallery section.

+===== Replacement BIOS ROM chips =====
+{{ :toshiba_t-series_support:images:t3200sx-bios-chips.jpg?400|}}
+I have started selling replacement 003CH BIOS ROM chips for the T3200SX. If you're currently in need of upgrading your BIOS in order to install a different hard disk, you can use my BIOS chip to get around any limitations you may have with your current BIOS. The BIOS that I am selling is the the 003CH Hybrid BIOS, which is a combination of the 003C BIOS with the faster VGA BIOS of 003I. The hybrid BIOS will essentially act as an older BIOS and allow you to boot any hard disk. With this BIOS, all you need is a disk overlay program to correct the hard drive parameters. I can also program an XT-IDE enabled BIOS chip for you if you wish. Both chips are a drop-in replacement for the old BIOS chip, and should work great in any T3200SX system.

-**Q: I have no picture or have a noisy picture**\\
-**A:** This could be caused by many things, but there is a chance the laptop lid open/close switch is just stuck in the on position. This rather low-quality plastic switch is designed to detect when the display lid is closed, and will cut the power to the display. It engages whenever the lid is closed, and since it is near the power supply the rod that engages the switch bends over time and may get stuck inside the switch. The symptom you will see is a screen that will never seem to turn on when you open the lid, or will have a noisy picture, due to the switch stuck half-on. If you cannot repair the switch manually, as a workaround, you can disable it by removing the plastic rod that engages the switch. Please see the gallery section for an image of the switch.
