Re: More vDrive Games

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 cause...

Re: More vDrive Games

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...

Re: Zip to MDV

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 a...

Re: QL Network Protocol(s)

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, b...

Re: QL Network Protocol(s)

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 s...

Re: Hello & help needed with QL networking and TK2

Hi All, As per Martyn's suggestion I've started a new thread in the 'Hardware' section for the QL network protocol discussion: https://qlforum.co.uk/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 pro...

Re: Hello & help needed with QL networking and TK2

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!

Re: Hello & help needed with QL networking and TK2

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 rudime...

Re: Hello & help needed with QL networking and TK2

Martyn, I'm using the Minerva 1.98 ROM that was provided by Tetroid's ROM switcher - I'm assuming it must be the unpatched version. I'll just have to stick with the JS ROM at the moment. Unfortunately, I can't burn a newer version of Minerva as my (home made) EEPROM programmer can't handle the 512Kx...
