I bought these PS2(F) to Serial(F) adapters explicitly for my Windows 95 frame up restore, replace. retrobright, and rebuild. Both of them do not work for this application. My old Microsoft Serial mouse was no longer working right. I found a Microsoft mouse with a PS2 connection (still shrink wrapped) here on amazon. It's the same mouse as my old one, but instead of a serial connection it has a PS2 connection to the PC. After opening the new mouse box, I found a Microsoft brand PS2(F) to Serial(F)F adapter. Apparently most of these red boxed Microsoft mice came with one. I used the Windows95 machine's keyboard to install the drivers. BOTH of these adapters fail to let the PC see the mouse. So I tried the Microsoft adapter that came with the mouse and sure enough the mouse works fine. I went back to test these two adapters and they are still not working (the PC does not even read a mouse attached to it). After some research I found that the Microsoft PS2 to Serial adapter is one of the few that does actually work for an old system like this. I am using an AT Motherboard, Cyrix 6x86 CPU, and a Sounblaster 16 in one of the isa slots. I must add that I can not confirm if these 2x adapters here work at all, and the one star rating is based off my need for my specific application (For which neither adapter worked). They may be designed for some other application that I do not know of. But if your like me and need a windows 95 solution. My advice is to track down an old MS adapter or mouse that comes with one. I hope this helps others looking for a solution like I was. I'm going to add several pics of the MS mouse and adapter that it came with it.

Just a perfect adapter for the necessary job! So glad we could find so easily on Amazon. This is for an old piece of office equipment that may need an external optical mouse once the touchpad burns out.

Standard DB9 to PS2. Works fine.

bought it to work with old DOS system computer. Works fine.

I took a chance with these knowing they might not work...and they didn't. Your PS/2 mouse needs to support talking in a "serial" mode for these to work and most newer ones probably don't.

Great to find parts to keep an old PC running.

I saw the poor reviews and surmised it to be people complaining because they didn't know PS/2 mouse can't be converted to Serial mouse protocol without a serious change of logic. Instead multi-mode PS/2+COM mice were common and the plug could be physically converted to whichever one was necessary; there are some variations on how this was achieved, but Logitech and Microsoft standards were the most common.I tested this with a couple mice I have that I know use either electrical wiring, since I normally use them on a couple other retro rigs of min. This works with neither of them. In fact, the implementation is so bad the adapter has somehow PERMANENTLY FRIED my Super I/O card (2x serials, parallel, gameport, floppy and IDE/ATA) mid-use, to the point where my computer's BIOS had to be reset AFTER already unplugging the card, or it wouldn't POST (reinserting the card reintroduced the lock up every time, even when unpopulated).DO NOT BUY THIS TRASH. Even if it's a passive adapter, it doesn't even do that correctly, at least to any standard I'm familiar with.
