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… dlvr.it/TCnGK1

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. The video output depends on your intended usage. Accellerated CPU -> Highspeed digital. 68008 ->… dlvr.it/TCnGHT

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? Statistics: Posted by Utri007 — Tue Sep 03, 2024… dlvr.it/TCmh8k

Hardware • Re: QL Hardware Pause/Slowdown: By debugging I was thinking more about being able to slow down the display so, for instance, you can better see why moving graphics may or may not be interacting in the way they were programmed or checking that… dlvr.it/TCmGNC

Hardware • Re: QL Hardware Pause/Slowdown: The point about testing and debugging, is it not better to use software debuggers to set breakpoint, and analyse variables?Yes of course, for those who know how to.There is always that flaw, knows what we are… dlvr.it/TCmGMg

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… dlvr.it/TClpBv

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… dlvr.it/TClp8X

Software & Programming • Re: Talent 3D Designer: I might go back to it one day, but this time using quaternion instead of sin/cos. FrancoisHad a look at quaternions on Wikipedia. Didn't even understand the English there before I started looking at the… dlvr.it/TClNF8

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… dlvr.it/TClNDr

Software & Programming • Re: Talent 3D Designer: Hi Folks, Perspective animation requires no more maths than GCE 'O' level trigonometry. SIN, COS TAN and their inverses.What I meant was that before studying what's involved, the thought of all the maths… dlvr.it/TClNDg

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.... So now, F1 & F2 keys are replaced by 'x' & 'c'. That should cater for… dlvr.it/TClNDS

Software & Programming • Re: Talent 3D Designer: I started working on a 3D vector game/demo many years ago. Coded in C and assembly. I coded the trigo function using a lookup table in machine code. Each object could have its own 6 degrees of freedom… dlvr.it/TCl16B

Hardware • Re: QL Hardware Pause/Slowdown: Since the PCB plugs into the CPU socket, it would be possible to isolate the CPU's HALT pin from the motherboard.Oh, so the fact that HALT and RESET are tied together isn't critical to QL operations? If that's… dlvr.it/TCkKjs
