What was the value of the resistor (measured)

No, please test capacitance without card installed and without inserted in zxpand My multimeter measures it (own setting) My guess would be that wire capacitance of the short lead disturbes the signal line OR That an additional 10-100uF capacitor between 3.3V and ground will help against too thin wi...

Have you measured and compared the capacitances of the lines agains Ground? Especially the one of the 3.3V?

Welcome to our forums.
Enjoy, read and ask questions, were trying to help

You can delete the "almost"

I just ordered 20 for europe.
If no one is offering for UK I'm willing to send there too. No sending to rest of the world.
Prices when I received them.

Of that I'm not Shure.
But if mazogs didn't work without altering then it doesn't look into the systemvariable LASTK (which inkey does) but either uses the ROM call or own routines.

Inkey can only use single keys. But the ROM reads the keyboard by eight IN commands. Each can have five keys detected which makes the 40 keys. Games can do the same. But even with inkey you can use more directions. If the game takes T for up and V for down, F for left and G for right then R might be...
