It's just an RS232 DTE device so you just need the correct cable.

[ That would also make it fully compatible to Q40, Q60 and Q68. Still I'm reluctant to recommend the PC pinout - I understand the Tx as a strict retro board, so it makes some sense to keep original QL equipment like printers, printer interfaces or QL-taylormade serial cables directly usable. Were t...

Maybe if you asked Charles Ingley (@Bloodnok) nicely he could look into it?

Of course, someone would have to give him a complete functional spec. for each device.

That's incredible! So let me get this straight... this is basically intended as a replacement motherboard product? It will technically be about the same spec-wise as the original (but with proper D-SUB added, better video out and more convenient power requirements) but you'll still need to use your...

Hi Stephen, Really excellent work, getting the demo to run on a QL. Could an API be written to load in video files? Well, the code is written with the idea of being more flexible. The encoder program is actually a generic encoding function with a debugging main() calling it with specific parameters...

VERY GOOD !!!! I use QL-SD with SuperGoldCard ... It would be nice to allow the use of this interface also for SGC owners. Or including this feature in the new SCG ;) M. Hear! Hear! All that memory and CPU power hobbled by the storage. Tetroid, did you ever think of having a separate FPGA/microcont...

OK, file updated with proper m4v.h file, anyway, here's how the music works: The decoder uses the following value to IPC note table: int pitch_table[] = { 41, /* A */ 38, /* A# */ 36, /* B */ 33, /* Middle C */ 31, /* C# */ 28, /* D */ 26, /* D# */ 24, /* E */ 22, /* F */ 20, /* F# */ 19, /* G */ 17...

Bother! I forgot to update the include/m4v.h file in the source archive so I can't post the musical notes look-up table. I'll have to fix that when I get home.

OK, I have music now, but it really shows up the variable frame rate. OK, that is actually pretty cool :-) Especially considering that it's still written in C. While it's pretty hard to beat modern compilers with hand-written assembly code XTCC is non-optimizing and the code will always be slower t...

I understand. I had usable MDR files I was able to read (and use) in the vDriveZX once it turned up.
