Re: Retro computer festival

Nice video!

It's a pity that I live more than 1000km away, otherwise I wouldn't miss a chance to go to the museum :mrgreen:

I loved your video on the Dragon Meetup this year too, thanks a lot!

Re: CoCoVGA upgrade

If the two boards worked well together then it would be excellent!

In any case, I’d choose the 64 or 200, the one you are more comfortable with.

Re: Internal error when trying to log out of the wiki

It works as intended on my phone.

Try to delete the Archive’s cookies just in case.

Re: programming the GMC module (SN76489 chip)

You're right.

It´s a pity that the cartridge sound cannot be mixed with the dac output.

Anyway, having a psg is very nice as it does not take all cpu to make sound.

Re: programming the GMC module (SN76489 chip)

Does the same happens with the CoCoPSG?

I remember that I did nothing special with the JCB Microsystems Sound Extension Module to get the sound through the tv. I don´t know if they can be mixed though.

I can try to test that during the weekend.

Re: programming the GMC module (SN76489 chip)

You could try Deflemask or any other chiptune tracker, and load some SN76489 songs to see how they do it.

Re: Up Periscope

You didn't understand me.

If you have a DOS cartridge connected, the disk rom takes up some memory and makes Up Periscope crash.

On XRoar's menu bar, select Cartridge->None, then Machine->Hard Reset and finally, load the game with CLOAD and RUN.

I've tried that and the game works flawlessly.

Re: Hardware Forum Needed?

That could be a good idea, as the General section is already quite big.

What does everyone else think about it?

Re: Up Periscope

The version at the Archive should be ok.

Are you running XRoar with any DOS cartridge? If so, remove it, hard-reset the machine and try again.

The loading commands are CLOAD and RUN.

Re: Premier's Sprite Graphics Board

Thanks for the heads up!

If you desolder the whole green board, please take the chance of scanning both sides of it or otherwise take nice pictures of it for the wiki page.

Cheers,
Rob
