So its essentially the gameboy of vintage mice?
I'd rather not go thaaat far for a durable mouse though, heh. Not sure if I even have a PS/2 port on here.
Amusingly, since it is also serial device, one could put a USB to Serial cable on, then attach the mouse to that.
{no, I am not serious about that-- but it probably would work.}
That was the "Second generation" microsoft mouse. The first generation ones were so clunky, that I dont even feel the need to mention them except for how awkward they were. Literally painful to use and hold. Terrible things. This was the start of MS's push into ergonomic interface devices. While it does not look terribly so in the picture, think about it in comparison to........ The horror in the spoiler below.
The third generation of microsoft mice were noticeably more ergonomically contoured, but were "Too" ergo for left handers, since they had a kind of swept design.
That was the tail end of the 1990s there though, to early 2000s. After that, computers were becoming more mainstream commodities, and the desire to make 'Cheaper!' products overrode the previous market niches that computer electronics held in industrial, scientific, and university settings where investment into computer electronics was crazy expensive, and people expected good durable goods, and were willing to pay for them. As a consequence, as things become "cheaper", they were substantially less well constructed, and that's where the garbage interface devices we have now came from. The innards of mice from that era, and this era, are strikingly different.
These days you have those thin little reed style switches that break/jam up, resulting in the need for a replacement. Compare to the button switches found in older, more vintage devices.
Things back then were designed to last, and last a very VERY long time. These days, "Product Lifecycle Managment" is part of the business strategy, and devices are PURPOSEFULLY made to be of inferior workmanship to earlier models.
