if you have a non-working unit, please pm me if your led is just flickering slowly..
i will resend you a mcu.

If you're still looking for a serial scrollwheel mouse, I just ran across one that isn't the one linked earlier:

Also this guy claims his mouse is serial but the box is unopened so he's only going by what the box says:

Anyway, I'm kinda confused as to what the product on offer in this thread is. Are you making/selling an actual adapter, parts to make an adapter, or just a how-to guide?

All of the above I think. I just bought the PCBs, will get the parts soon for one complete unit, the other boards will stay on stock.

Just an update.

Had issues with the first converter I received, as no mouse was actually working, i.e. no cursor movement.

Then recently I received a replacement converter, which now has proven to function like initially expected.
Apparantly the previous problems had something to do with a firmware issue (?).

(me having no soldering skills, nor with MCU-programming, I ordered a fully pre-assembled kit)

So, while testing various options/hardware with this new one, I now even got it to work with that ancient(1999) Microsoft Intellimouse Intellieye optical mouse I wrote about earlier !
(it is a dual USB-native, connected via USB->PS2 passive adapter)

- Another thing I've learned, is that changing mice while converter is powered makes it not work.
If I do that, I then will have to cycle the power to give the converter enough time to 'reboot' and recognize/acknowledge the new mouse... or something like that. Or turn off power before switching, same difference.

i added the project to hackaday io:

To confirm, are these now being sold with the option for a fully assembled unit?

I'm tempted. I always found those very comfortable to use.

Finally i found some time to complete my multi i/o setup.

Do you have any kits for sale at the moment? 😀

i already ordered new pcbs.
it will take at least 8 weeks.

If one wants to build something like this, can anyone post a reply with:

For anyone interested in KVMs, it works perfectly well with a Level One KVM-0411

Thank you for providing this information. Did you try up to 1280x1024? Any lag?

Unfortunately, I'm unable to find any of these for sale. Looks like they were marketed in Europe.

Perhaps we can make a sticky list of known working kvm switches? I am using an 8 port Compaq KVM switch but unfortunately there is too much lag 🙁

+1

Too much lag using my IOGEAR MiniView GCS614A (4-port w/audio)

No, not that high. But in 1024x768 (max of my 386's ISA VGA) in Windows 3.1 feels OK for normal GUI stuff.
I don't play serious games utilizing the mouse as the main controller on this machine (was there anything anyway?) so my experience with the adapter is limited to only point & click in GUIs or adventure games, where the adapter does fine. Even if there is a lag it doesn't really hurt for these tasks and goes by unnoticed.

Hopefully this can be fixed.. also have now a new KVM with this issue 😳

Have you been able to pin-point what characteristic of the KVM is causing this lag? Like a sampling issue, or there being a sort of check the KVM is doing every x milliseconds? Considering that all PS/2 to serial protocal converters I've tested have had this issue (about half a dozen), chances are good that it is not something trivial to fix on the side of the protocal converter. I suspect the issue resides in a firmware or hardware hack for the KVM. I hope I am wrong.

Not sure as i also have a Commerical one which has the Same issue too 😒
someone suggested to rise the clock speed of the mcu and recompile firmware, but i don't think this will fix it.
Due do its some kind of timing issue. Had no time to try it out.

i also will do another batch of pcbs 😀

Sounds like the fix is on the back burner. Aw well. In due course 😀
