The Sinclair QL Forum

Looks great, fitting nice into the QL Case. Thanks. I'm espcially proud of the power switch in disguise of the Reset button. ;) Not 100% sure about the mechanics yet, the USB connector next to the HDMI connector is still in question. I did not receive all components yet. Also, the design is based o...

Confirmed.

I’m just hoping for a decent expansion connector. In 40 pin with 2.54 mm raster okay for you or still too small? ;) Oh wow, we could finally have a QL with a built-in disk drive. I made every effort the case does not need to be modded, and you talk of floppy disc instead of my wonderful SD card &qu...

Q40/Q60 Linux can also deal with byteswapped filesystems, not that this would be of much help.
Personally I think byteswapped images should be corrected, not used. But given the practical reality this is a good QPC feature.

By the way, how is the QL keyboard connected? (I don't distinguish the QL's membrane keyboard connectors). P4 and P18 allow direct connection. The keyboard cables can be angled to the right and are then just long enough. I would recommend a replacement membrane, because it is more robust. Ideally, ...

Yes, that makes a lot of sense. Almost nobody understands the implications of endianess with the IDE bus. Several guys even insisted that their byteswapped Qubide images were correct, after three attempts to explain. It is hopeless.

This is how the prototyping PCB for my new QL mainboard looks: tmp.jpg Before some get too optimistic: It won't support the microdrives, which will be replaced by SD card "drives". However, the original microdrive LEDs and the corresponding internal connector will be supported, to preserve...

Nice that QxlwinReader worked for you Phill. You will also find it a very useful tool in general if you work with native filesystems. Wolfgang has done a great job there.

SD images can also are byteswapped sometimes, e.g. if SD-IDE converters are used with native hardware. Which is not unlikely for some Qubide or even Q40/Q60 setups.

Could it be that you have no proper Qubide image, but something byteswapped by an IDE conversion device? That's the usual mistake people make. 68K Is big-endian, Intel not.
