WeMOS D1 mini ESP8266-12F CH340, ArduinoIDE 1.8.9 WinXP - does it work or not?

Question

I want to compile and program the WeMOS D1 mini in ArduinoIDE I am using WinXP and ArduinoIDE 1.8.9. I have tested different versions of board esp8266 and only with version 2.5.0 it compiles and uploads. Can someone write briefly how the WeMOS D1 mini behaves, how the LEDs flash, how to use it?...

I soldered the PS/2 cable, WeMOS gets power, WebServer works but the computer I connect to the PS/2 keyboard port doesn't detect the keyboard and it doesn't work.

I have compiled with the ps2dev library the latest i.e. 0.0.4 and it is the same as with version 0.0.1 - message:

Why doesn't it work?

Sketch d1mini.ino is here - I just changed my SSID, password and IP details:

I soldered according to this:

From the script it seems that every key press on the WebServer page should appear in the Serial window and the LED on the WeMOS should flash and nothing happens - something is wrong, just what? My WeMOS has different pins than the older version of WeMOS ???? The author refers to this page:

I did a test sketch and it works - it spits out in Serial over and over Hi I'm Wemos:

void setup() {
    Serial.begin(115200);
}

void loop() {
    Serial.println("Hello I am a Wemos D1 mini Pro");
    delay(2000);
}

Jeeeest

I changed the IP 160 to 167 in the sketch - the one shown by WeMOS when I compiled with IP 160. Now it bangs nicely :-)

Previously on WebServer I had Status: 0 in red at the bottom now I have Status 1 in green:

Great stuff - I'm typing on my laptop and WeMOS plugged into the ZX Spectrum emulator's PS/2 port

WinXP SP2 64-bit
ArduinoIDE 1.8.9
ESP8266 Board 2.5.0
ps2dev 0.0.3
WebSockets 2.3.5

And these ArduinoIDE settings:
