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...

Re: Hello & help needed with QL networking and TK2

Hi Martyn, Thank-you for your comprehensive explanation as to what could be happening - you were exactly right! I added the missing header to the file and it loaded as expected - Success! Of course, this now breaks the loading of BASIC files on the stock roms :roll: - I'll have to make my 'file serv...

Re: Hello & help needed with QL networking and TK2

Well, I've tried a variety of different NET ids for both the file server and the QL, but I'm still getting the same problem. I also did some experimentation on the header & data checksums to see how TK2 would respond, and it responded as expected: - an invalid header checksum yielded no ACK resp...

Re: Hello & help needed with QL networking and TK2

Hi Martin. Thanks for the reply. I have been using that document as a reference for the original QL network protocol. I assumed that TK2 would be backward compatible with the original protocol as the documentation only mentions a modified protocol for the broadcast message and the FSERVE protocol. I...
