Re: Merging video output?

I guess its not too hard now to wire them up once the hardware design is somewhat settled? The thing is, there are many different ways to do the hardware mixing, some are simpler than other, some provide more benefits than other. My idea is to implement a few mixing alternative in software, and see...

Re: Merging video output?

This is what one hour of hacking around managed to do: MultiCutron.png I've to give Kudos to Xeron for having designed something which is not full of global variables all over the place :) I had to do some ugly things to the rendering and initialization code, but it kind of mostly work. Muhahahahaha...

Re: Merging video output?

Interesting!

At least this showed one thing: Even when not perfectly in sync, the resulting video signal is still valid, and we can generate valid video data in the normally blanked area of the screen... you did some left and right hardware overscan :D

Re: Blake's 7 feedback and review thread

The main reason for the interleave to not be regular, is that when you have reached the end of the track, you need to loop back to start, and of course you can't reuse the sectors that have already been set, so you may have to jump over some. So basically the ideal interleave pattern is also pretty ...

Re: Merging video output?

@NightBird As you probably figured out, I'm not able to answer these actual hardware questions, hopefull ISS or Mike Brown can help on that :) @Chema I think it's a case of "Go big or go bust" :) @ibisum That may or may not be difficult, probably depends of how Oricutron is implemented: If it's pos...

Re: Blake's 7 feedback and review thread

Could you check with this version, it should have the CRC correctly fixed.

Regarding the interleave, if you could give me more details about the problems :D

Re: Barbitoric has incorrect CRCs?

Ok, I did a correction pass on the Defence-Force download for the following files: - Barbitoric - Born In 1983 - LCP2004 / BuggyBoy - OricTech - PushingTheEnveloppe - VIP3 - VIP4 / Quintessential - Zero fx Some were duplicated :p Hopefully it did work fine, but I've not tried any, so if somebody fee...

Mike reacted to these latest developments, and he sent me the following email: Well, it looks like you idea does work, ISS managed to reproduce the suggested system, but he had to use one extra ULA for that to work: http://forum.defence-force.org/viewtopic.php?f=8&p=16637#p16634 If dropping clock pu...

Re: Blake's 7 feedback and review thread

Hi. Not sure if we missed this reference (for the first post: http://mag.mo5.com/actu/127023/blakes-7-un-point-click-dapres-une-serie-tv-sur-oric/) We did not have it, just added it. Dbug, any chance of a new FloppyBuilder which corrects the CRC thingy? Oh, and I think Fabrice Frances noticed the g...

Re: Speech Synthesizer for Oric?

There was two native Oric speech synthesizers, a british one based on a the standard SPO-256, and a French one from CMPI which spoke more "french", which I did record some time ago: http://www.defence-force.org/download/clair_de_la_lune.mp3 The main problem was that it used the same address range as...

Re: Merging video output?

You can see how the reference SYNC is 1/2 of the 12MHz period before the child's SYNCH's. (...) @Dbug: I think It's possible to have the communication between the various Orics with synchronized code. So, what's next? :) First, I've to say I'm impressed by your work :) Is the master ULA absolutely ...

Re: Merging video output?

Exciting :) I was wondering about other benefits of having a common clock. Do you thinks that technically it probably means that the communication between the various Orics could be done with synchronized code that does not even need to acknowledge anything and just bang the busses as fast as they c...

Re: Merging video output?

Yep, I think the parallel port is the best option for communication between machines - easy to drive and no additional hardware. Maybe it will be better to use it as kind of (a)synchronous serial interface with two lines STB (for output) and ACK (for input), emulating something standard as protocol...

Re: Merging video output?

Nice work! With two Orics, we could do something much better than what can be done with one Oric, imagining the power of a machine with three Orics inside, whaou: Could do some crazy things :D Assuming you manage (I hope!), do you have any idea on how the three machines could communicate with each o...

Re: Blake's 7 feedback and review thread

I still think the first thing would be deciding the extra characters that are needed, if any, because I'm afraid ther won't be enough room for all! I assume we can have a different font for each language, so we can have all the extra characters for french? As far as I remember, most of the French g...
