Re: SD extension on ZXpand+
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...

Re: SD extension on ZXpand+
Have you measured and compared the capacitances of the lines agains Ground? Especially the one of the 3.3V?

Re: JOY81 - Programmable Joystick Interface for ZX81
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.

Re: Atari joystick without ZXpand+
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.

Re: Atari joystick without ZXpand+
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...

Re: Atari joystick without ZXpand+
Joy81 is no miracle and we can make new boards if you're interested (or others as well)
It also offers multiple key presses and diagonal keys not only up and down.

Re: Atari joystick without ZXpand+
As long as games use the inkey equivalent they don't need to be rewritten. That's what zxpand offers to the zeddy or otherwise it's own API.
Joy81 on the other hand implemented the exact keyboard behaviour and so games need not be rewritten.
