Interrupt vector and Minerva

Hi there guys, I found that my most recent demo release is not Minerva-ROM compatible. Because I have no intention to willingly deny Minerva users to run my demos, Im interested in looking into what causes the incompatibility. Luckily for me, the issue can be reproduced using Qemulator! However, I l...

Two MDVs for package&postage

Hej,

I removed 2 microdrives and have no longer use for them. If there is something that wants them, I can post them for package and postage.

On no reactions, I'll bin it in a week or so.

Kind regards,
Wietze

Re: QSound and Assembly

Hi guys,

I've released a little prod using the qsound. It can be found here: https://www.pouet.net/prod.php?which=95891

It also contains a YouTube link in case you do not own a qsound.

Kind regards

Re: QSound and Assembly

Quick followup; it seemed that setting individual AY regs using trap calls did work.

So I used this and that worked like a charm.

Kind regards,

QSound and Assembly

Hi there, I recently obtained a QSound device, and now that I cobbled together a working oqtadrive, I *should* be able to get my own programs running on the QL using the QSound! However, currently that is not yet the case. I was wondering if anyone went this way, or got some suggestions for me to tr...

Re: QSound and QPrint Interface

Forgive me for asking, but do you guys happen to know what the hardware addresses of the QSound are to directly address/control the AY chip? I assume they are directly exposed?

Re: OqtaDrive

Ahhh. I figured out what I did wrong, I consistently wired A<>B mirrored. So my upper lines were lower and vice versa. Now that I have that corrected, all is well, and I have a working oqtadrive. Now I can finally use the oqtadrive, hopefully in parallel with the QSound and move on to get some track...

Re: OqtaDrive

Attached you find the log running with debug. As soon as I have it all connected AND power on the QL, the logging hangs/stops. (As seen yb the log) From the log, we can see that the Nano is correctly flashed and serial communication works. However, it looks like there's tremendous noise at least on...
