Rex 6000

Get your calendar, contacts, tasks and much more in your wallet (yes, your wallet). Though you probably would break this device if you did have it in your wallet, it is small enough to put there. This is the first real REX device that is a microPDA. REX has been until now a PCMCIA (PC Card) pocket organizer, but the new REX 6000 is changing all that. This new REX is stylus based, and has 4 times the memory of a REX 5000

REX runs its own special operating system, though they functions are much like a palm. Unlike its predecessors, the REX 6000 has a touch screen, enabling users it access and add data more easily then ever before. Its display is a 9-line 240x120 black and while screen, which is amazing to see on a device that is only .2 inches (1/5") thick. Though it doesn't have a program like Calligrapher, it does have a digital keyboard, which is a great improvement over the old "select the letter" input method. The REX 6000 also comes with a staggering 2mb of onboard memory. I doubt you know enough people to fill up that memory.

There are some pic of the cracked Rex 6000 of a friend... He at some point while it was in his front pocket, the screen developed a series of cracks converging on a large ink blot.  So, being the naturally curious he is, he disassebled it.  You may click on the images to get the full-size pictures.

Here are all of the parts to the Rex 6000.  The LCD screen ribbon cable is actually soldered to both the LCD panel and the REX, so there's no hope of replacing just the panel.  The large golden disc is the speaker, as best as I can tell.


Here's a close of of the good stuff.  Sorry my flash got a little in the way, but you can read all that's readable.  Note that the two larger black chips are absolutely unmarked.  No words, letters or numbers of any kind, no matter how closely I look at it.  This picture has a lot more detail if you look at the full-size image.

tips and tricks for your rex

Here is a bunch of useful information that I have collected about the REX 6000. You may find something new or useful here.


  • Looking for somewhere to buy a REX? Try eBay.

  • To put your REX 6000 to sleep, press and hold the Home button. When the PDA is locked and the PIN dialog is showing, you can press the Back button as well.

  • Instead of hitting the Back button when viewing web content, hit the little W in the upper-right corner of the screen. This is a lot easier than switching from your stylus to your finger.

  • Unlike Memos, the Task List does not support categories. So, instead of cluttering your Task List with every little thing you need to do, create Memos for different sets of tasks, leaving the Task List for the most important stuff. For example, "Things to Do", "Things to Get", "Things to Fix", etc. Place square brackets, "[]", in front of each item, then insert an "x" between the brackets when you finish. Crude, but it works well.

  • Use the Sort By button on the bottom of Contacts. It's the one with the up-down arrows next to it. Click on it, and you can sort by First Name, Last Name, or Company. Make sure to place the company name in the Company field of your contacts.

  • You can also enter in the company name in the Last Name field, and then enter the location in the First Name field. This way if you want to list, say, multiple Wal-Marts, you can do it and you can immediately tell from what city its from. (Thanks Todd E.)

  • If you have a lot of memos, you can shorten the list with the category filter. First, assign categories to all of your memos, such as "personal", "work", "misc info", etc. Note that the REX automatically places locked memos into the "private" category. Click on the little downward-pointing v at the top of the display and a list of categories will pop up. Select a category and only those memos belonging to that category will appear. Select All Memos to list all memos again, or No Category to list unassigned memos. This also works well for Contacts.

  • Another useful trick is to assign categories to your contacts. If you are working on a project (say, buying a house), you can place all of the related contacts under one category (like "House"). Change the category by clicking on the "All Contacts" menu at the top, and you will see only those contacts who are assigned to that category.

  • To edit the categories in your REX 6000, first edit a memo or a contact. Click the Category button. You are now in the category manager. You can add New, Modify, and Delete categories from here. Before you hit Ok, just be sure that only the categories that you want assigned to the item are checked.

  • If you keep your REX in your pocket, purchase one of those flat packages of breath mints. These are about the size of your REX. Keep it in your pocket in front of your PDA for extra protection.

  • If you have the leather wallet holder for your REX, you can bolster the protection by fitting one of those credit-card sized calculators into those four triangular holders on the side opposite the PDA. Be careful, as it's a tight fit.

  • IntelliSync can be somewhat flaky at times. If at first you don't succeed, sync, sync again. Sometimes it takes a few syncs to "figure out" what's going on.

  • Often, a conflict window will pop up. If you think it is mistaken, then it probably is! Hit the Ignore button, and sync will proceed. During the next few syncs, IntelliSync will probably correct the problem and the errant dialog will stop appearing.

  • When you use the USB dock, wait a second after the beep for the light to flash, then press the button to sync.

  • The REX 6000 draws power from the dock when it is plugged in. This includes both USB and serial versions, as well as the PCMCIA slot. Your batteries will not be drained when you sync, so sync as often as you like! The PDA will fall asleep in the dock, and the batteries don't recharge, so there is not much point in leaving it there.

  • You do not need to tell Windows to unplug the REX when it is in your PCMCIA port. Windows will complain when you pop it out, but as long as sync has completed, this is harmless to both the PDA and your computer.

  • When starting REX Tools, you can hold down the shift key to prevent it from downloading the file list from your REX, saving time. This is useful if your are just going to upload files to the REX.

  • If your REX is password protected, then you can hit Cancel when REX Tools asks for your password. This won't affect file uploads, since the password is only used to fetch the file listing from the unit. If you don't need to see this list, you can save time.

  • The PIN will not protect your REX 6000 unless you set the "Lock Rex" time to Always. There is a bug in the firmware that allows anyone to get to your data if this time is set to anything else.

  • Be careful when you tap the space bar on the on-screen keyboard. Tapping too low can trigger one of the application buttons. Without warning, the REX will simply discard your changes and switch to that application.

  • If you forgot your PIN, and can't get into the REX, the only solution is to Initialize the PDA from REX Tools. This will erase all of your data, which you can restore by performing a full sync afterward.

  • After Initialization and re-sync you will have to fix a few things. Previously locked memos will be unlocked. Bitmap pictures will have to be reloaded. Add ins will be gone, but those in Adder will still be there (names may be wrong or blank). Personal information will have to be reentered.

  • After Firmware Update a few things will go away. The first two rows in Adder will be gone. Any patches that you installed will not be there. However, all of your data and your Extras will still be in place.

  • The first thing to try when your REX 6000 is acting up is to reset it. Stick the end of a paper clip into the little hole in back, and it will reset (be gentle!) You should see the "REX" title screen for almost a minute, then it will go to the home screen. The time should still be correct; if it isn't, then there may be another problem.

  • The REX 6000 does not clean up its memory when you make changes. This causes the memory to fill up, even when simply modifying data. Make sure to defragment the memory periodically, either automatically during Web Sync, or manually through REX Tools.

  • If you are experiencing mysterious crashes in your REX 6000, you may have a corrupt timezone database. Go into the World Clock, and look at the locations available. If they have all disappeared, then you will need to reload the database. Symptoms of this problem are mysterious crashes when using built-in functionality, and the REX not being able to keep the correct time. Use REX Tools to upload this WorldClockFirst31.rex file to your REX 6000 (make sure to remove the .txt extension).

  • If your REX 6000 fails to sync completely, then try this. Go into your "Program Files/REX6000/IntellisyncForRex" directory, and delete the files "tables.itb" and "tables.caf". Perform a full sync and everything should be fine.

  • If your laptop computer will not sync with the REX in the PC Card slot, you may need to free up an IRQ. Intellisync needs a free IRQ for the COM port to communicate with the REX. If your laptop is using all IRQ's, then it won't get one. Try disabling an unused COM port through the Device Manager or the BIOS Setup. You can also pop out a PCMCIA modem to grab its IRQ.

  • Note that the REX appears as a modem device when plugged into a PCMCIA slot.

  • If your computer is being shared by the REX and another PDA, you may have sync problems caused by the software that detects when the sync button is pressed. Set the sync software to "manual", or remove it from your startup programs.

  • If you are having problems adding, deleting, and modifying items in your REX, the internal database may be corrupt. This can happen if a sync is rudely interrupted. The only solution to this is to keep trying and hope it fixes itself, or to initialize your REX through REX Tools. Note that this will erase all data in the REX, and you will have to perform a full sync to get it back.

  • If you are having trouble synchronizing Notes, or they won't sync at all, you can try clearing out the Notes from your REX and resynching. In REX Tools, save any Notes files that you have changed since your last successful sync, You may want to back up all of your Notes in your PIM as a safety precaution, as well. Now delete all of the Notes files from your REX using REX Tools. Switch to Intellisync, and make sure that all of the verification options are turned on for Notes. Now hit the Synchronize button. When it asks to confirm the changes (mostly deletions), hit the "Re-sync" button. This forces Intellisync to copy the Notes back into the REX from your PIM.

  • If your update your firmware, make sure your batteries are fresh! Weak batteries can cause the update to fail, and your REX will not operate. To force a firmware update, hold down the Home and Reset buttons (paperclip into little hole in back) at the same time, then place it into the cradle and start REX Tools.
