Do you know the ref of this connector ?
This one seems HS...
-
up :bump:
-
ELBOX would know as one of their products fit into the Blizzard ppc slot. i could find out some of the signals are, but im too busy at the moment as im working on something else.
a new graphics card could be made to fit the Blizzard PPC card.
*correction* i already know what some of the pins do.
here's something some of you did not know, theres 12v & -12v located on the card but is not used.
-
I've heard the BlizzardPPC connector being spoken about as a 'Mini PCI' connector for whatever that's worth...

It is not a "standarized" mini PCI... but it is a pci bus. probably a proprietary for phase 5.

Dude, seriously? Help the guy out or don't help the guy out but teasing people with information like this is just a really sad thing to do.

Oh ? Really ?

Which product would that be?
-
DCE (http://www.dcecom.de) re-released the G-Rex 1200 PCI busboard before they left the Amiga market, which uses that dreaded connector. They probably have that information, but they have shown in the past they are not really interested in helping out anyone regarding their past Amiga products.
Good luck!

I guess you should get some clues from the support chips on the BPPC and the BVision... I don't recall any PCI host chips on the BPPC or the BVision (could be implemented in CPLD or FPGAs maybe?)... But I am pretty sure the Permidia2 was designed to interface to a PCI? No? The BPPC connector could well be just the PPC CPU signals brought out to a header...
-
i may of got it wrong about Elbox.

The adapter board for the GRexx has a great big CPLD on it. If you look up the part number, you'll see it's a PCI compliant part. My guess is that it probably implements whatever is missing on the Blizzard itself.

If I had to guess, I'd say you were thinking of the GRexx, which is phase5/DCE.

Well that suggests the BPPC port is little more than a header on the BPPC's bus... If it were a PCI port the G-Rex would require little logic to bring that out to standard PCI slots :)
I remember asking Ralf Schmit about the port some 13 years ago, and recall him saying it was standard PCI... But I don't know how much he know about the hardware... He could have been referring the whole interface with the BVision...
-
Maybe someone have a defective BVision ??

Well, there is a bit of CPLD glue on the BVision also.

I would suggest that is to interface with the PCI compatible interface in the Permedia2 :)

I don't doubt it. Pity there doesn't seem to be any obvious DMA between the two cards (perhaps there is and I'm just not aware of it). I recall that the GRexx was supposed to be capable of supporting host <-> PCI device DMA.

I doubt there is any, BVision was clearly build on a budget... Speaking of which, do you still have your A1200 setup?

Of course. My signature is entirely up-to-date :lol:

A simple yes would have been sufficient... Ok, then do you want to try getting AROS on your A1200?

Do I take it that at present only AGA native modes are supported? If that is the case, I will be a bit stuck as I currently have no 15kHz capable display devices.

Bah! I'm stuck in the same situation :(

I might have an old TV tuner card somewhere...

first Bvision the world to have a 250Mhz RamDac and has a vertical refresh rate of 200Hz and there *may possibly* be more to come from it`s PCI bus beyond 43Mhz.

sigh..

In the old VGR site there were interesting pictures of the prototype used to create CGX Permedia2 drivers and it had a PCI slot with a standard PCI card plugged in. I guess it didn't have much glue logic. There were other pics like a nVidia TNT(2?) driven WB on a G-Rex.

I fail to see how this information assists the OP, but I have to ask, a 200Hz refresh rate is a bit pointless isn't it? On my CRT there's no appreciable improvement of picture quality beyond 85Hz refresh.

I have to echo Karlos here... You are boasting a little too much about the size of your RAMDAC... remember it's not the size, but what you do with it that counts ;)

Wow what a massive ramdac you have!
Will you show it to everyone?

let me see,you are wrong picture quality has improved this is before i changed any settings,*maybe* this is something i done.
image is a little bit sharper more defined as for OP yes it is faster *maybe* its something iv *not yet* posted.
the PCI bus alone gives me improvement in speed,this is why i don`t need to use a screenmode lower than 800x600 when testing any PPC games.
whats your *refresh rate* with highest *screenmode* setting while retaining 16.7 million colours?
UPDATE CORRECTION: should read upto 200Hz refresh rate.

nah best not,mite be accused of boasting.

What, does a faster vertical refresh rate magically change your CRT's dot pitch?
,this is why i don`t need to use a screenmode lower than 800x600 when testing any PPC games.
800x600 may be technically impressive for P2 3D gaming, but like most 3D game fans, I tend to use rather less archaic kit for the job.

UPDATE CORRECTION: should read upto 200Hz refresh rate.
Well, I don't use 32-bit display modes on the BVision as they are a complete waste of video memory, but I do recall 1280x1024@75 Hz working. The highest it goes is 1600x1200, which is a limit of my old CRT.

Refresh Rate

RamDac

not a good idea to confuse users. now lets see who know the answer to why im getting a better image (and yes i do know the answer) and i did say *maybe* i may have done other things to produce this but one thing is for sure i did not do any software changes with the screenmode.
