Re: New Forum

First of all, thanks for all the work, the QL forum is pretty much the last life line of the QL world. The update seems to have fixed my RSS troubles. Previously the contents of RSS feed changed depending on my logged-in status, which resulted in already read messages showing up as new, which was pr...

Now it gets just warm but not hot.
This is cool!
Ah, I was going to ask about the Turbo bit! That is cool :-) Well done.

I have a soldering iron this small but still prefer the drag technique ;) Nice job anyway, I just wonder if it's normal that it would get this hot.

Re: QSound and QPrint Interface

Here you go guys, ROM v1.94 with the HW I/O registers relative to ROM again. There have been a few other fixes as well that I noticed during manual code review, but nothing you should really notice.

Re: QSound and QPrint Interface

Have you problem with play command? any "out of range error"? Yes, I almost always get that error. PLAY 'CDEFGAH' is always accepted (but of course no sound). PLAY 'v8CDEFGAH' sometimes just plays scale (but not always) PLAY 'v10CDEFGAH' always complains 'out of range' (as do all other co...

Re: QSound and QPrint Interface

Hm, the device should never hang, so this is at least strange or a bug in the device. v1.93 rom hangs QL on both these Basic commands: OPEN#3;QSOUND BGET#3,a OPEN#3;QSOUND BPUT#3;1,2,3,4,5,6,7,8,9,10,11,12,13,14 On QPC2 you get err_bp for BGET, with expected noisy output on BPUT. Unfortunately I do...

Re: QSound and QPrint Interface

But QSOUND device on v1.93 rom seems to be tripping up my player. I did a 'crafty' (that'll teach me ;) ) way of detecting whether output channel was to PSG file or the QSOUND device by looking for EOF on output file (ie. initial empty PSG file), on QPC2 it was OK but causes QL to hang. Hm, the dev...

Re: QSound and QPrint Interface

Thank You so much for your effort, and don't worry, I will give you one, but first I need to solve my problem with the position of the ROM. Great :-) The tunes are offset on pitch, but I suppous that this is related to the clock of the interfaz and is not easy to fix on software. Yes, the frequency...
