USB VIDEO ON THE DENEB?

[Darrin]

I was checking my emails this morning and I had the usual "on sale" email from Tiger Direct attempting to get me to part with some cash.  One item was a USB to VGA video adapter.  In the same category was a USB video card:

Assuming some sort of driver could be written, is such a device a viable alternative to expensive Zorro cards on the Amiga via the Deneb card?

I wouldn't mind enjoying "resolutions of up to 1280 x 1024 at 24 bit color" for $65.   :-)

USB video dongles of this kind are horribly slow on full-speed USB2 connections.

I can't imagine they'll be worth a flip on the Amiga, driver or no.  

You know how people freak out about "oooh nooo it doesn't refresh fast enough!" regarding Amiga emulators on the PC?  Yeah, this'll give them something genuine to complain about.

LOL.  You could be right.

I used Siamese on the Amiga using the normal serial port to retarget 8 bit to 24 bit screens to a PC using it's graphics card in resolutions up to 1024x768 using nothing more than a 68020 with 6MB RAM.  It was certainly usable for Workbench and for Word Processing.

I use a Cybervision 64/3D, but it's really used to provide a pretty Workbench as most applications launch into native Amiga screen modes.

For that sort of use this might be OK and it is certainly affordable.

Thanks for that info Chris.  I figured that if Siamese could work then there was some potential here.

I'll throw 20 Euros into the pot if you want to try.  Do we have 3 more volunteers for a worthwhile project?

Speaking about potential, I think for embedded machines without onboard gfx (aka EFIKA), an adapter that uses less than 2.5W (that's the maximum allowed for USB devices) would be better suited than a Radeon whatsoever. At least for my planned Touchscreen-Car-Computer project :-)

Sounds interesting.  I never had a chance to set up my Efika with MorphOS 2 while I was home as I was too busy with my kids and the Deneb card (24 days off work flew by!) so extra graphics card options are always welcome.

About that "bounty" -- even if I'd get the adapter, this would not come with an obligation to complete the project. As said above, the task would be rather complex.

I absolutely understand and I'm still willing to chip in.  Unless my Cybervision breaks down then I personally don't have a need for such a device, but I think it would be great for the community.  Besides, you've saved me way more than 20 Euros by providing me a $20 Ethernet option instead of a more expensive Zorro card so it's the least I can do.   ;-)

Seems like the tally is
arnljot €20
Darrin €20
HyAmi €20
amigadave $20

So seems to me that the total is €60 + $20. Getting there Now we just need Platon42 to accept

So that's €60 + €13.86 = €73.86

I'll up my contribution to €25 and cover the remainder plus P&P (S&H).

[Darrin]

We need some sort of classic option.  Software Hut seem to have sold their last "new" Cybervision 64/3D cards and the only Cybervision card I could find on eBay was listed at $266.

Wow. I wouldn't have thought of people comming up with this. If somebody could collect the bucks (I have no PayPal account anymore), buy that thing and send it to me, that would be great. Thanks!

It's because we trust you and your abilities.  :-)

I'm in the USA, so I'm not a good candidate to do the purchase and sending, but if we have an honest member here in Europe who is willing to do it and who has a Pay Pal account then I'll send him my share of the money if he passes me his details.

How about the guy who runs Versilla?  He does Pay Pal, lives in Germany and is 100% trustworthy?  Does he post here?

Platon42, I can wire the full amount to you first. Then the pledgers can send me their part of the amount to my paypal.

So I suggest:
1) I(or other) wires full amount up front to Chris
2) Chris confirms receipt of the funds in this thread
3) Pledgers pay their pledged part of the amount to my paypal or whoever else put up the money up front

Statement: When I wire the money to Chris I consider it payment for the following service: That Chris will aquire and look at supporing a USB graphichs card for the Poseidon USB Stack and Deneb USB Card for the Amiga. However, Chris is under no obligation to actually deliver this, this can be due to technical constraints or constraints to his time to spend on this.

That sounds perfect!  I'll send you my share by PayPal assuming Chris agrees and you're ready to send the funds.

Cheers.

Can I just point out that I use CybergraphX 4.  ;-)   :lol:

Thanks for making the effort (and thanks to Chris for looking into this).

You could give us Angelina Jolie's cellphone number and the IP address to connect to her wireless shower-cam.

@all: im repeating this for th last time: thanks folks, but i do not need a refund on this. im happy to support.

So where do you want me to send the money?   :-?



That's very kind of you.

In that case, I have another 25 Euros here which I'm willing to pledge to any other useful USB device that Chris would like to examine in the future for developing possible Posseidon drivers.

The cruel & crucial point is still that I have to read that brainf*cking x86 code. Anyway. I'm at a stage now that I have identified and understood the display memory (16MB) accessing functions and can display a nice gradient. I also have found the registers that are used for the frame buffer start addresses, so I can actually switch between two memory locations now.

I have yet to find out the calculation for the video registers (I'm using a pre-recorded setup right now) and the delta-compression scheme, among other things of course.

But things are progressing well...

Well done Chris.  I'm glad to see you're still working on this as I thought it was a dead end.  I guess you like a good challenge.  :-D
