Hardware • Re: Announcing the new "Gold Card" - QIMSI Gold: Hi, thanks for creating such a nice device!
I would like one too, can you put me on the list for the second batch? Thanks I put you on the waiting list.

StephanCould you put me to waiting list… https://t.co/je0PU5N1Ls

Hardware • Re: Announcing the new "Gold Card" - QIMSI Gold: Standard QIMSI are no longer made. But QIMSI Gold can always be used as standard QIMSI also.

Hardware • Re: Announcing the new "Gold Card" - QIMSI Gold: I'm interested for a QIMSI regular or Gold card. What is availability of them? If I get Gold card do I need to use HDMI or is SCART just fine?

Software & Programming • Re: Talent 3D Designer: Hi

Quaternions are an extension of Complex number that can be applied to 3D Graphics.

But can get a little abstract, I found using a matrix to present 3F Space easier to manipulate than using complex… https://t.co/eBs5UFScjd

Hardware • Re: QL Hardware Pause/Slowdown: Hi

I thought about bending CPU pins out and soldering directly to the CPU. Sounds straight forward, but prone to damage if too much heat is applied to the pin.

Maybe wants a dedicated circuit board.

The… https://t.co/LaQPplDX52

Hardware • Re: QL Hardware Pause/Slowdown: Oh, so the fact that HALT and RESET are tied together isn't critical to QL operations?The QL would still work if they were not connected. If you have a spare 68008, you can try. Just bend pin 36 (HALT) to the… https://t.co/TOL7dUmI9H

Software & Programming • Re: Talent 3D Designer: Hi Folks,

Azerty PC keyboards don't have easily accessible function keys, when I developed the game using an external keyboard....
