I'd like to share one interesting finding: switches made by ITW I've never seen before. They're used in old Fulcrum trackball I've recently added to my collection: https://forum.trackballs.eu/viewtopic.php?f=17&p=96 Illinois Tool Works make quite a lot of various switch designs, but their current li...

Will do that later. By the way, you're welcome to register there.

As for stuck bearings - don't discard them! They're of fine quality, and relatively easy to restore with some patience and basic tools:

Meanwhile, out of curiosity I've finally discovered who is that MVP your trackball was OEMed for:

Regular plain vanilla ball mouse. Dirt-cheap or free nowadays. It uses the same quadrature detectors and slotted shutter discs as your trackball: you'll just need to re-wire things.

P.S. Avoid Logitech mice, as many of them use proprietary detectors, not discrete quadrature ones.

I doubt you'll be able to find a converter: Sun always was a "niche market", and prior to your CH it was only ITAC known to me who made compatible trackballs... I'm pretty sure your best bet is to replace the controller. Not a big deal BTW, and if you don't want to deal with Arduino and similar thin...

Very unlikely indeed. Never owned SGI, but on old Apple machines serial pointing devices were not normally supported, at least by MacOS itself. That doesn't mean it can't be done, though: during my Mac-addiction period, it was impossible to find ADB trackball in my country - so being a baller, I've ...

Yes, at the end of article I've posted is a link to another one, specifically about conversion:
https://forum.trackballs.eu/viewtopic.php?f=16&t=18

DT225 was converted by very similar technique, but I haven't finished the article about it yet.

It does not matched any of the one on diagram. Well, then you'll need to search further. Joystick Technologies / CH Products has made trackballs with almost any interfaces ever existed - including quite rare and proprietary ones. For example, mine arrived with giant DB-37 connector: http://images.v...

Since there are only four wires, do you think it's just ps2 protocol? I've never seen PS/2 or ADB devices with non-standard connectors. AFAIK MiniDIN-4 and MiniDIN-6 were integral part of these standards. As for yours, it looks to me like CD-i pointing device connector (kind of serial): http://imag...

Yeah, though I'm not familiar with the symbol. Kindly see below.

It's just manufacturer's logo: stylized "CH" letters.

Updated version: Ploopy v1.01 – Project Ruby.

GameBall have been teasing a new finger-operated trackball design for gaming on and off for a few years now. It's just been announced that they'll start selling them early next year (2020), though. GameBall will be available in early 2020. All as expected: https://old.reddit.com/r/Trackballs/commen...

Funny: their first thumb-operated trackball after decades of classic devices...

Probably offtopic, but what's 'pro membership' actually is? If the donation I've paid makes me eligible, I'm interested.

Done. Hope you'll be able to keep DT running.

Yes. In fact, I'm just positioning my palm without any thinking about it: it's "auto-adjusted" to the ball & buttons in such a way that they're conveniently accessible. Maybe it depends from the hand size, though.

Hmm, I've never had any discomfort using original MTE. Don't have Ploopy currently, but it seems to be an exact copy according to photos...

Tremendous project with excellent documentation! IMHO it's not pure MTE clone, but merely a hybrid of MTE and MacAlly Qball, as it uses ball bearings (not roller bearings, as stated on project pages).

Can't take it seriously, unless actual sale begins. They're routinely "updating" the release date for several years, with words like "last changes", "streamlining design", "some final improvements", "will be available next year" and so on - but nothing beyond computer-generated images was created ti...

Yes indeed, Expert implementation was a biggest fault. Funny enough, cheap entry-level Orbit have butter-smooth scrollring...

Magnet was really bad idea (and its removal a common thing) - so apparently Kensington has stopped installing it in latest Expert batches. I've bought mine several years ago, and it was already without magnet.

Recently there was a story when on some game competition the winner was using trackball, BTW...

I also can't recall any case when simultaneous scrolling & pointing was needed. As for convenience - using the ball itself for scrolling is much more convenient for me than dedicated wheel/drum/ring. If some button is used as "scroll mode switch", you don't even have to move your hand or fingers to ...

This iMouse T50 can be an affordable backup trackball device for me! (I hope it can be wired or has BT though)

Neither.

Hello, The landscape is changed a bit indeed. Most remarkable "new players" are Elecom and Adesso. IMHO, the most advanced trackball today is Elecom Deft Pro: plenty of features and decent quality. In fact, it;s my primary home trackball now. At the office, I use Kensington SlimBlade: very good devi...

Do you guys have any experience with foot switches. How durable are they? Are they fully programmable without dodgy china software etc. Any other recommendations for foot switches ? Many years ago, foot switches were a popular addition for trackballs (either as add-on accessory or included in packa...

I'm wondering since when a desire for comfort isn't an actual reason...

I've heard it wasn't successful indeed, and quickly discontinued. But I'd like to find one and add to my collection anyway...

(I hope they make a separate trackball too eventually),

They've did it several years ago: it was Perixx Peripro-302.

Hi all, Does anyone know what switch it is? http://static2.keep4u.ru/2019/02/11/DSC045223f4a784a16c6cef7.md.jpg Full gallery here: http://keep4u.ru/image/SYfrx http://keep4u.ru/image/SYfrw http://keep4u.ru/image/SYfrb http://keep4u.ru/image/SYfr8 http://keep4u.ru/image/SYfrk http://keep4u.ru/image/S...
