Sellets from CN offer them on amazon.

However this is not Mini USB but USB-A

Exactly, I couldn't find anything like in your picture

I found two sources in the U.S.:
Shipping may be cheaper within the U.S. here: https://www.performance-pcs.com/cables/usb-ca … m-minia-60.html
Free shipping world wide here: https://www.moddiy.com/products/4-Pin-Molex-t … Cable-40cm.html

Thanks a lot, yes the first one wants 20euros to ship a cable over to Greece. For the second with free shipping the total is about right.

In the original thread there was talk of using 9600 baud for the "high speed" mode and implementing the logitech command to change to said speed. The purpose was to allow high precision use with unmodified logitech drivers. Was there ever any progress on this?

Has the issue with no Windows 95/NT drivers been solved when using 19200 baud mode? If I recall, that was the main hurtle for my use of the product. And 19200 baud was required to eliminate pointer lag when behind several KVM types. I recall there had been attempts to hack some Logitech drivers to get around this, but I don't know what became of this.

EDIT: I had a setup which let me use my Arduino to blank out the MCU so I could reprogram the unit, but I have since disassembled that setup so I'm no longer available to test alternate firmwares. I may have one blank MCU that I can still program, but won't be able to erase it again easily.

What I was referring to in my previous post was the next step in trying to solve the 9x/NT problem. By using 9600 baud for the high speed mode, you can use unmodified logitech drivers.

You can use the 6 pin ISP header and erase/write the chips with a parallel port

I don't recall 9600 baud working with any generic or branded Logitech Win9x/NT driver when I did my tests. If there has been some positive progress in this regard, I'd be interested.

Because it was never implemented properly in any version of the firmware. In order for a logitech mouse to work at 9600 baud it must first be initialized at 2400 baud and then the driver sends a command to change to the higher speed. The response to said command was never implemented properly

Looks like your memory is better than mine. Thanks for providing this clarity. I'd also like to know if there have been any progress on this front.

Translated PS2maset to english, hope its understandable now.

Drivers for 19200 Baud Mode:

Cutemouse 1.9 is recommended for MS-DOS.

19200 Baud mode reduces Lag, and enhances Tracking Speed.
Especially in SVGA Games for example.

Is it possible to power it on a system without USB?

it just uses USB Connector for Power only,
you can power it from any 5v source.

You can also use Molex to USB Cable and connect it inside the PC.

Saved the page. I probably can't afford them for a couple of months, but a couple will be useful at some point. Just bought two Molex to USB cables from China.

Also got an ISA PS/2 card to try out on systems with no onboard serial.

I really gotta stop buying everything in sight 😀
