It offers four programmable buttons for customizable workflows and includes a PS/2-to-serial adapter for flexible connectivity. Designed with an ergonomic shape and rubberized base, it ensures comfort and stability, making it a cult favorite among professionals who value reliability and efficiency in their workspace. ## Description Product description Computer accessory desertcart.com If you're used to a traditional mouse, then the Logitech TrackMan Marble FX may take a little getting used to. But despite its large, clunky appearance, this mouse has it all. Designed for those with limited desktop space, the TrackMan Marble FX remains stationary. You operate it by moving a large marble with your fingers while a sensor inside the mouse interprets the movement. Solid and well built, the TrackMan Marble FX has a large, eye-catching red marble. Its weight and rubberized bottom keep it from sliding on your desk, and the curve of the mouse fits most hands (except lefties). Those with small hands may find it hard to reach the left-click mouse button, making double-clicking tricky. Installation is not as quick as most plug-and-play mouse devices, as you must install Logitech MouseWare software to fully take advantage of the TrackMan Marble FX's features. However, the manual walks you through installation, making set up easy and quick. Perhaps the nicest feature of this trackball is the four programmable buttons. During setup, you can program which buttons you want to perform certain functions. Most will want to set the far left and right buttons as on a typical PC mouse. However, the two middle buttons can be set for functions such as universal scroll, auto scroll, zoom, drag lock, or HyperJump and CyberJump--pop-up windows with shortcut functions in Windows 95 and Internet environments. If you're in the market for a trackball and have the time to learn to use a new type of mouse, then you'll want to consider the TrackMan Marble FX. Its durability and low maintenance make it superior and easy to use.Pros: Sturdy and well constructed Programmable buttons Dirt resistant Cons: Difficult for those with small hands Not designed for lefties Requires software installation Review: Logitech Trackman Marble FX t-CJ12 The best trackball ever sold - The best trackball ever sold. PERIOD! The T-CJ12 TrackMan Marble FX was sold in retail stores through the 1990's to ~2000. It was suddenly pulled from the market due to infringing on an obscure patent. During its short life span it became the a favorite pointing device of many users: CAD workers, gamers, the handicapped, artists, . . . In the years since it has developed a cult like following. I myself used T-CJ12s in CAD work in the 1990's both at the office and at home. One of my original T-CJ12 trackballs is still in use twenty years later. What makes the T-CJ12 so great: the near perfect relaxed hand position, the large fulcrumed primary buttons, the large oversized ball manipulated by both thumb and fingers, this is the only track ball where you can hold the ball between thumb and fingers, and an unique duck bill palm rest. Trackballs take some time to adjust to; they work best when set sensitive. One flick of a finger should move the cursor anywhere on the screen. The first few hours can be difficult; you will need to set the acceleration and sensitivity. After a month of using a trackball few users will ever want to return to using a mouse. The T-CJ12 is a 4 button mouse. Techies, CAD guys, gamers and such can go to town programing the buttons to do what they want. But these twenty year old trackballs work just fine as a three button mouse right out of the box. I am using a T-CJ12 on this modern Windows OS computer as a plug and play device. The trackball and two big buttons work like a regular mouse, the small white button either is scroll lock or if you are on a link opens that link in a new tab, the small red button is non-functional without installing additional software. Disclaimer: I buy and occasionally sell these. I have dozens. From several rare "New in Box" to some just for parts Buying a used T-CJ12 Online: 1) Check Logitech Logo on the Spine - it should be clear and distinct - it fades from years of use and can be completely worn off 2) Check Label on bottom by S/N for a small hole - a hole here (OR covered with sticker) accesses the hidden case screw for repairs 3) Check Small Red Button - if any white is visible this indicates extreme wear as the paint has worn off 4) General Color - is unit dirty or sun faded 5) General Cleanliness - look for grime around buttons and cord 6) Beware of supposedly new units in the box - it is impossible to tell if a decent used unit was carefully returned to the box from a photo. If the seal is open ask for photos of the contents. Buying a new T-CJ12 1) The box is sealed by a single circular seal that can easily come open. It is hard it find verifiable original sealed boxes; I have a several. 2) Often trackballs where returned to their box after a period of use. When these units come to market more than a decade later they are often unknowingly misrepresented as new or slightly used. 3) Few new units remain - a new unit should have: shrink wrapped manuals, sealed software, a neatly bundled and tied cord, a warranty card and . . . such as the instructional hang-tag should be attached between the PS/2 plug and the included 9-Pin serial adapter. Making the Connection A T-CJ12 needs to connect to a PS/2 port to work. Modern computers particularly laptops do not have PS/2 ports. So to use a T-CJ12 on your computer you will need to add a PS/2 port. The easiest way to do this is to buy a dual PS/2 to USB adapter. This dual adapter will add both a powered PS/2 keyboard and powered PS/2 mouse port to your computer. I order these from China for about $1 each for the small cube kind and $3 for the cable kind. The key here is these are powered adapters, not just a cable end adapter which will not work; I see T-CJ12 being sold with cable end adapters that work with some USB / PS/2 mice but not with the T-CJ12. The T-CJ12 needs a true PS/2 port. If you have any questions about this item fell free to ask. Addendum: In late 2014-2015 I sourced the electronic parts, cables, and vintage main board connectors. I can now retrofit a USB cable and plug it in place of the dated P/S2 cable and plug. I have tested these conversions for several years on multiple track balls. This is a simple plug and play conversion for a new or lightly used trackballs; on older well-worn units removing the bottom cover and cable typically exposes internal damage to the case, particularly where the cable wraps the ball housing by the optical sensor. The original design allows for such an exact fit where the optical sensor is held in place by pressure from the cable wrapping past it; on many older units the sensor falls loose when the case is opened; totally repairable with the correct techniques.

It is the only pointing device that allows: grasping the ball between opposed thumb and finger(s) for fine movement, using any single finger normal movement, and swiping the ball for speed on its three steel bearing for extreme movement. The long duck bill housing provides a heel rest for comfort and stability; a law suit for patent issues regarding this feature lead to this designs sudden withdraw from the market place. That and it's never equaled functionality have led to it's now cult like following among those users in the know. In use repositioning the device on your desktop (location) and changing the angle (rotation) allows for significant hand relief; similarly elevation changes help your forearm and shoulder. I should clarify in using this device nearly all arm movement typically done with a mouse can be transferred to minimal finger and wrist movements with the arm and shoulder stationary for significant periods. With the heel of your hand below your little finger resting on the duck bill and your forearm on edge of the desk or a pad nearly zero arm movement is required, however changing position prevents issues. I have personally have used these since their introduction; recognizing their usefulness on my always crowed and cluttered desktop. For years I preformed CAD work with hundreds of drag and drop operations an hour. Personally I have had damaged hands since childhood with lifelong muscle loss and arthritis like issues. Additionally my hands are large (XXL/XXXL, Size 11/12). The large ball and large well-spaced buttons on the Logitech Trackman Marble T-CJ12 really makes all the difference in the world. I can not comment on suitability for the posters issues as he does not specify his personal issues. Any hand will cramp or fatigue if used improperly; with out rest or change of position. This trackball allows for an variety of positions. It is right handed only. It is suitable for all but the smallest baby like hand. It is suitable for a wide range of disabilities: missing a finger or two, but not thumb; stiff or scared fingers; the bed ridden. . . The two main buttons are large and easy to access, they and the third white button (default scroll) function as plug and play under all modern versions of Windows; the fourth small red button is best left non-functional, but can be brought to life with additional software. This vintage pointing device requires a true PS/2 port be added to your computer with a USB dongle; not a USB adapter. The difference is a dongle shows up us as an added USB device before you plug in the trackball, it is not just a plain cable adapter. The dongles cost less than $2 online. The original poster emailed me and kindly pointed out that he did not request a buying guide, nor did he ask ask for instructions on how to clean his peripherals. All too true, but with this device being fifteen years old most offed for sale are well worn units that buyers need knowledge on how to test to avoid bad units. He felt I was impertinent; perhaps he forgets many read these answers, not just he. I was solicited by email to answer his question by some computer that knows I have answered such questions in the past; I do not go searching forums for questions to answer. I adapted text I had at hand to give the poster significantly more than he asked for. I apologize for being verbose. He farther seem to think I failed to indicate if this device was suitable for his needs, in the end that is his decision. I will confess if he had been a little clearer with his multi part question, I perhaps could have answered him more precisely. He criticized me for not speaking directly to hands thought I mentioned every part of a hand in my response; as to long hands that is subjective and entirely unanswerable, though I did say it was suitable for my very large hands. Lastly I believe he called me a "Tech-Nerd" perhaps intended as an insult; but wow thanks, all the years in those old brick buildings not wasted. Lastly anyone have a question fell free to ask. Use care buying these trackballs used online. I have thought several times about writing a buying guide for them, but then unscrupulous sellers would know how to fake the points of a good one. I lived abroad for a number of year when I returned to the states I found my stash of T-CJ12s plundered. So in 2011 I set out to build a stock for myself and those in need. I bought several dozen; many in the box. I have sold just one in NIB to Australia in 2013 for a silly price.How to buy. Look at the listings see what the best ones look like. Do not trust new in the box or open box unless you trust the seller; many of these were returned to their boxes after days, weks, months, years of use back in the day only to be sold now. Meanwhile order a PS/2 dongle from China for $1. Test the dongle on your computer. Does it show up as a USB device? Good Now, buy track ball that looks good, from a seller that takes returns. When you get it look it over. Do not plug it in yet. Are all four pads on the bottom? I the bottom label complete? Pop out the ball, takes about eight ounces of force. Does the ball have any scratches you can catch with your fingernail? Does the ball have any dimples you can catch a pencil point in? If so the ball is bad, return it and try again. Look in the cavity where the ball was. There should be a little black (actually very dark red) square of plastic visible; this is the IR (infrared) window cover, occasionally it is missing or loose, if so return the trackball and try again? Next look at the three bearings inside. If it is an uncleaned used trackball here you may find a dust bunny or several; rarely the bearing are cracked at their base. Clean them with a dry paper towel, we are just knocking the big dust and lint clogs out. Look at the two big buttons are the cracks dirty? If so cut some narrow strips off an index card, fold them half and run them through the cracks to get out the worst of the lint and grime; this is just testing you can clean later. Pop the ball back in. Now check the two big buttons for audible clicks not just at their center but: front corner, back corner, left edge and right edge. A good button should audibly click at every position. Similarly check the two small buttons. Now rest you hand over the trackball. Get comfortable. Click all the buttons. Move the ball. Move the ball for five minutes in every direction, does it click or catch? If it clicks there is likely a scratch you missed. If it catches there is likely a dimple you missed. If either is significant pop the ball and go back and look. Now the first subjective test. Spinning the ball for five minute should have started to loosen the bearings, in my experience it takes about 100 hours of use to free up a track ball that has been setting for over a decade; that's a month for most users. With your finger near the top flick it down to send the ball spinning quickly. When your finger hits the desktop start counting fast. I just scored four on a trackball I rate at about 50% good enough for everything but gaming. A new old stock T-CJ12 can score 8, 10 or better. To put that in perspective a half turn of the ball is a half to full screen width depending on the speed of movement; but with a finger flick I can send the ball through multiple revolutions. In use I can place the pointer anywhere with a single finger motion, even crossed multiple screens. Enough digression. Look at the pins in the end of the plug, all there? All straight? Plug in your dongle. Restart. Plug in the T-CJ12 restart. You will not have to do the restarts again. And with some system you may not need to do them initially. I though all installation glitches were gone then had to go through silliness when I upgraded to Windows 10, so just do the restarts once to make sure all is correct then afterwards plug and play works. Now call up a program and test all the buttons for function. You like it want to keep it. To clean it: never get it wet, slightly damp cloths only, unplug it, dish detergent and water for housing and cord, nearly dry alcohol pads for grime around buttons, no acetone or fingernail polish remover it will melt the finish. **Q: Has anyone tried using this Tracball on Windows 8.1 ....... successfully??** A: Yes, the vintage Logitech Trackman FX Marble Model T-CJ12 one of the most popular pointing devices ever produced is plug and play supported in all modern versions of Windows all that is required is that the computer have a true PS/2 port. A PS/2 port is most typically added to modern computers with a small inexpensive USB dongle that adds two PS/2 ports one for a mouse and one for a keyboard; please be aware that simple single cable adapters sold separately and included with some older pointing devices merely change a PS/2 cable end to fit a USB port will not work for T-CJ12 trackballs as they are merely cable adapters and not powered PS/2 ports. Using the wrong adapter makes many people believe their FX does not work. In plug and play mode the Trackman will have the full functionality of a modern three button pointing device. The fourth button the small red button is not assigned a function. For most users this out of the box performance is fine; if not various software packages can be ran under Windows to more fully configure the FX; it is beyond the scope of a quick to discuss more. **Q: does it work with mac book pro** A: Yes, it requires a ps2 to USB converter to work. No additional software needed. **Q: Does it have a scroll wheel?** A: No. However the small white button near the top of the device functions to toggle on and off "scroll lock" when hovering over text or web pages allowing the large track ball to serve as pseudo scroll wheel. This feature is the default plug and play function of the third button under all modern versions of the Windows OS and when activated displays a small stationary scroll icon in place of the cursor. Also in browsers (Explorer, FireFox) when the third small white button is pressed when scroll lock is not toggled on and the cursor is hovering over a hyperlink on the page the link is opened; typically in a new tab, but definable in browser settings. These are the default plug and play functions, of course the buttons’ functions can be redefined with software and will behave as programmed. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Logitech Trackman Marble FX t-CJ12 The best trackball ever sold *by L***Y on May 7, 2015* The best trackball ever sold.

Yes I said 15 years, or at least since they first came out. They are the best trackball that was ever made,ever made. They fit your hand like no other trackball out there including any that Logitech has made since. I really hope that Logitech will make them again, because you can't beat them. They are so expensive now that most of the time you can't find one that you can afford. The few that are out there that are new are being sold for close to $500. That is just unheard of. Of course those doing that probably won't sell it or maybe they might. Used ones are usually REALLY USED and the buttons will go out sooner or later. But if you can find one that has the Logitech logo intact on the top and hasn't been rubbed off, then it wasn't used much because that is the first thing to go and it doesn't take long for that to go, maybe about a year or less of use. The one I have just purchased, the logo is sharp and so I know that it hasn't been used much. Even this one wasn't cheap, but it was cheap enough that I was willing to foot the bill for it because you can't beat this trackball. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/47176248-logitech-trackman-marble-fx-trackball](https://www.desertcart.at/products/47176248-logitech-trackman-marble-fx-trackball) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-05-11*
