That would be great!

Just out of interest - I assume this capture of mdv non QL format data you've been working on with Tony could also be used for the ICL OPD cartridges so that they can be captured/dumped and then viewed or manipulated to some degree in QemuLator or even on a real QL? That would be interesting. I did...

I'm thinking about what format to use for the resulting microdrive image. QLay's MDV image looks general on the surface, but it's not, it only works because emulators know the image format and that is specific to QDOS (512-byte sectors, etc.). Another issue is that it doesn't explicitly store the mi...

I guess, I have to switch to supervisor mode, disable interrupts and/or redirect them to my code. And I guess I have to save/restore the relevant memory contents to somewhere else, if I ever want a fighting chance to restore things, if that is even possible. Anything else?

I now have these items: Not sure if on Mac it's the same, but on Windows often the logic analyzer won't immediately be seen by PulseView (try using fx2lafw type). When that happens, the Zadig utility (comes with PulseView) can be used to install the proper firmware. After that, it should then show ...

This is certainly something I'd be keen to do when circumstances allow (I'm a 24/7 carer with little time or space to do something like this), but if you can let me know exactly what I should get I'll get it in ready so I can give it a go as circumstances allow. Hi Tony, The logic analyzer I have i...

I'm pretty sure now that the existing dumps (at least of BAUD & a couple of others I tried) of the OS disk programs we have in the downloads section are corrupt (am going to try and make a dump on the hardware to manually compare BAUD byte by byte as it's small, or I may try to make new serial ...
