Yes, I used Hex Editor on a ql_bdi.bin file, did a byte flip and...I got a file that was recognised as a qubide file by the Qubide program from José!
Re: QL on MIST FPGA board
I guess my contribution for QL on MIST is not mainly QL-SD, but debugging the TG68 FPGA core, so it does not just run Atari and Amiga Code, but also QL code. The TG68K.C (which is probably used on the MIST) is a successor of the TG68 and already has the QL bugfixes included.bixio60 wrote: - better situation will be to emulate Qx0 if ever possible
I saw Peter Graf partecipate to this , at least to support QL-SD, any opinion?
The original author of the TG68 and TG68K.C, Tobias Gubener, had debugged his core by letting it run in parallel with a real 68K CPU in hardware. Since I do not have such a setup, it was a much harder task to debug the CPU. A misimplemented instruction usually does not cause a problem immediately, but often tens or hundreds instructions later, or never at all.
I have not yet looked at the MIST implementation, but from what I heard, it is a close implementation of the original QL. The Q68 is closer to the Qx0, especially keyboard and highcolor graphics are identical, so a SMQS/E port might be easier for the Q68 than for the MIST.
I could port QDOS Classic from the Q60 to the Q68 myself in one day, so if SMSQ/E is as nicely structured as QDOS Classic, the amount of work should be similar (for someone who is familiar with SMSQ/E, which I am not).
Re: QL on MIST FPGA board
I'd love to try out the QL core on my MiST. But unfortunately it's broken.
The tiny USB Port ist torn apart the mainboard. I was always careful, but
I killed it.

I would go back to the supplier and explain there was an accident, they may repair the board.

Re: QL on MIST FPGA board
The not very reliable µ-USB-Connection is a known problem (not only) with the MiST.
But MiST has a work-around built in:
Here

Is a description on how to retrofit a 5V DC Power Jack to the MiST (The PCB is already prepared for this mod).

Re: QL on MIST FPGA board
Yes, I know the DC Power Jack mod. But I have in mind to
install a new and more reliable USB connection.
Btw: Lotharek sends no invoice!

I would do the DC Power Jack mod, the mini USB socket looks too flimsy.
The surface mounted pads that have been been torn off the board should be repairable. Try posting photograph, there maybe advice available.

I didn't open the case yet. Therefore I only have this picture...

Re: QL on MIST FPGA board
Hi,
Here is a picture of the MIST board:
It looks like you have ripped the micro USB connector off the board, the electrical connection are surface mounted, so could be wired up to the original connector or new connector mounted elsewhere.
