ok, I'm pasting here some of Rodolphe's reactions below, it's getting too messy, someone could miss it...
>I will only support 66 & 100 MHz bus !
>The 66 MHz bus will access at full
>speed to the PCI bridge while the 100
>MHz will access to 1/2 (50 Mhz) speed
>the PCI bridge ( the chip I choosed
>cannot run above 66 MHz... sorry).
>so, for 100 MHz and only for 25 people
>this time I have to design a special

>connecte to a 50 MHz PCI bridge...not
>easy...but I'm sure it is possible...
Hmm.. and what about thinking about overclocking at 133 MHz (I mean CPU) and then we get 133/2 = 66 MHz for PCI? Or... why making 50 MHz... what about making asynchronous transfer between PCI and CPU (something like CT60<->Falcon) to get 66 MHZ PCI for 060@100? ... look at that guy with 92.5 MHz with old CPU..

>Videl --> Super Videl !

great great great great!!! :)) I have to say post such this are such such motivating!!! Rodolphe, you're true Atari fan!! About DSP: hmm... for me, as DSP coder, would be nice to have at least some compatibility with old DSP.. but new DSP from TI... isn't bad too... so... what about TWO DSPs ?? One(56301) will be placed at old address space ($ffff82xx) and the new one (where we aren't limited with any compatibility issues) could be placed anywhere... hmm.. what you think about this solution?
Ok.. that's what I would to say.. once again, RODOLPHE THANKS!!!

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
