it's used in avionics, dunno for what, but I have a customer there.

Bought one. I am testing it.
It's really big, and well-made.

The ps/2 version of the Ametek Traxsys TrackBall looks like this one, which is USB. The page says other protocols are available since it's defined "50mm industrial device".

eh, for serious high computing tasks, here my laptop is only used as portable X11 and vt220 terminal to a remote machine that thereby can be a Xeon big iron machine with a lot of computing power, CPU, ram, disks, etc etc, and with the proper cooling system, while the laptop just needs to properly ...

I bought a PowerMac-G4 in 2004, a second-hand machine used during a show-room, so a bit scratched and damaged on the plastic, but I don't care about this. I used MacOSX 10.4 for a couple of years, then I loadedGentoo/Linux, configuring the ...

I't's sad to hear that Apple is slipping in the quality department


Well, let's also talk about laptops. My brother bought a maxed-out full spec MacBook/Pro in 2015. He used it with care, but since he is a mechanical engineer, he needed to run a couple of programs for calculating FEM.

FEM is ...

By the way, Apple has made specific Windows drivers for it. I'm not sure if the Fn key works without it.

What about Cherry ML?

and, anything that the firmware of the keyboard controller can do?

is there any example for the anti-key-ghosting algorithm to be followed in the design of the keyboard controller?

I wonder if the integrated trackball is really of 500 DPI ...

Too scratchy switches and trackball for my taste.


found this video that shows what you mean with "scratchy". The dude in the video says the CHERRY G84-4100 can be better if you lube the switches, and he shows the difference, with and without lube.

p.s.
The G84-4100 is listed here at 56 Euro ...

Thanks, guys. My friend was considering buying a new keyboard from Amazon, but since it's not worth with the money it costs, well ... there is a G84 for 35 euro in the UK, second hand + 15 S/H, and this price *might* be acceptable considering that he needs a very small PS/2 keyboard with a built-in ...

KRO stands for key roll over , and it normally goes after a number, e.g. 2KRO means 2 key rollover , and a keyboard has " 2 key rollover " *if and only if* it can support 2 keys pressed at the same time no matter when it happens and which keys (META? non-META?) they are.

I have read that most ...

ah, that comment of mine in that topic. I thought it was more appropriate opening a dedicated topic specific for the G84-4400 rather than commenting on that one, useful to hear more than one opinions

I haven't understood your comment.
I don't need the keyboard for gaming if it's what you meant.

so is it bad?
here it costs around 140 euro shipped, I wonder about the ratio between quality/cost

I accidentally found this post while I was googling.

I like the Cherry G84-4400PBGB-0: it comes with 83 keys, US layout, built-in trackball with 2 buttons, and PS/2 protocol. I'd also like to hear some feedback, and even about the built-in trackball.

thanks

So, since the RadioShack is bad, I need to look for a better trackball.
Thank God I haven't bought it yet (thanks guys for the warning and hints).

I need three buttons, and I need to operate on a 1024x768 screen
B-5XXMP GPNB-5XXMP looks the right model to look at.

I am located in Italy.

yup, and even cheaper. I'd also like to hear some feedback about the built-in trackball.

guys, what do you think about the Cherry Slim Line?
They are Compact-Keyboards

The Cherry G84-4400PBGB-0 comes with 83 keys, US layout, trackball 2 buttons, and PS/2 protocol.
