A second ANTIC?

[José Pereira]

Hi, here (your countries it's probably the same...) we say that the best ideas are when we are at the W.C. or on the sleeping Pad...

 

W.C. I donn't think so, they're probably "sh..." ideas!

On the sleeping Pad I had many...

 

But I had this one right now whem I was lunching (anew way to get ideas: good or stupid, or crazy, or ... all of them!...

 

And here comes the idea:

"If with a second POKEY you double the nº of channels. will it be possible double colours, PMs,...?"

 

I am not Engineer, don't now anything about soldering and only know A8 adresses/registers, but if we only have 4channels and four registers and with a second POKEY we get 8channels with just the 4 available channels... it will be possible to have the same 9colour registers

and double them with a second ANTIC?

 

 

Any (crazy or not ) anwers to this

 

Greetings.

José Pereira.

Color registers on GTIA not ANTIC. I think they are externally tieing together or merging the POKEY audio out whereas merging video out of GTIA isn't that simple.

People have done it but not easily since they can't share the same set of RAM chips plus you need a second GTIA as well.

 

Another solution is triple GTIA with each one driving R,G,B which potentially gives more colour options and 512 or 4096 colour palette depending on mode.

 

Problem is it's very unlikely to ever catch on so there will probably never be any software to take advantage, and both require extensive modification of a machine.

Something like this? Dual Antic Hack

VBXE gives you more.

Thanks to the event, I first thought you meant this 'second' Antic:

Using the area outside the Atari800WinPlus window gives you even more.

well, they said the same about dual pokey way back when and the fact you had to moddy the software to appreciate the upgrade fully, seems as though somehow suitably modded games did come (like zybex and some other zeppelin releases)

What's that? Very Bad for XE machines card? Wires running all over the place that only EE students think it's a masterpiece while software people think it's a mess.

 

I was thinking something you just plug into a socket like the dual POKEY upgrade.

VBXE stands for Video Board XE

 

Maybe you should ask Google ? Or even do a little research on this forum before posting such an "opinion" ?

 

You can think anything you want, it doesn't matter at all. Fact is, the VBXE EXISTS in about 140 pcs (including current run) since 2007 and its capabilities are much better than any hypothetical "dual" ANTIC/GTIA" nightmare.

 

Mounting vbxe inside the computer is only slightly more complicated than dual pokey. Mounting it outside (using PBI or ECI) is impossible due to lack of appropriate signals.

To be fair VBXE is one of the neatest upgrades I've seen as far as wiring is concerned. It all depends on the job you make of installing it. As for the software side, the only gripe I ever had was with the text mode colour attribute system. However, it's nonsensical to say that it's bad for the machine unless you're a died-in-the-wool purist, in which case you might as well leave the machine alone. If better quality video and an improved colour palette are what you want, VBXE is an obvious choice if you can afford it. Even if you don't want one or you can't afford one, you can't say it's "very bad". The fact is it was the first comprehensive video upgrade of this type to get off the ground and three years on it's still in demand.

I did put a question mark on my statement so I wasn't declaring that to be the case and I did say "XE machines" not XL (maybe it's a mess there as well). I read in this very forum how people were desoldering and soldering stuff like sockets to install the board so that's obviously a mess for a software person and original poster is in this catagory like myself. And for a software person, it is very bad for their XE machine if they attempted such a thing. I also praised it as far as a EE person goes. I would think dual POKEY is also a mess if I had to install a socket and desolder things.

Your last statement is quite correct. 99.9% of the VBXE horror stories were down to people being unable to desolder an IC from the Atari mainboard. Dual POKEY (and presumably dual ANTIC) requires the exact same amount of desoldering as a VBXE installation (unless the board is socketed, as are many XLs - so that's less mess on an XL). Although, admittedly, VBXE requires a precision socket, so there'd be some desoldering required on the XL too.
