Ok, a quick update to this - I've modified mdvtool to correct the block checksums and I can now read the .mdv files.
It's strange that the block checksums are incorrect, but the data header and data checksums are fine - they all use the same algorithm.
Anyway, the problem is solved, if not the ...

Hi All,

I've recently been working on my own microdrive emulator (just for fun!) - and it's been working well on various .mdv files I've tried that have been posted here in the past (eg. cavern.mdv & GamesCart.mdv), and with .mdv files created with mdvtool.
However, these (vDrive) .mdv files don't ...

If anyone's still interested in this, I recently had need of mdvtool for a DIY microdrive emulator I'm working on (more about that in the future).
Anyway, I've fixed the Zip file import and added a 'create' command to create blank .mdv files, as well as squishing a few other bugs (but probably not ...

Derek, Please let me know how you get on - particularly with the documentation, have I given enough details for someone to successfully built it?

Martyn - Thanks! Looking forward to seeing your QLUB project in the future, it's somewhat more ambitious than my little effort!

Peter, Glad you like it ...

Well, thanks to the help received from everyone here, I have now got my simple QL network file server working well enough for me to release the source code - it can be found at: https://github.com/dandelion-labs/QLAN
This provides an inexpensive (~15 GBP) route to adding SD storage to the QL, with ...

Hi All,

As per Martyn's suggestion I've started a new thread in the 'Hardware' section for the QL network protocol discussion:

https://theqlforum.com/viewtopic.php?f=2&t=2829

(I though the Hardware section was more suitable, as both Martyn and I are working on microcontroller based QL network ...

This is a continuation of a thread first started in the 'Help for New Users' board:
https://theqlforum.com/viewtopic.php?f=11&t=2826

I'd just like to say a quick thanks to everyone who has contributed to this topic so far, it has been very interesting and informative.

To continue on from Martyn ...

Hi Norm,

If I ever discover any info about the QL beyond what is already published, I will definitely pass that knowledge back to the community!

Hi Martyn,
- the FSERVE code is quite a step-change in terms of complexity -

Yes, I suspect that I won't be able to make any great inroads into how that protocol works. Only having one QL makes 'snooping' the network traffic a somewhat one-sided affair!, plus my knowledge of 68000 assembly is ...
