What is the maximum rating (in terms of resolution & frequency) of this board? Will it be able to do high resolutions of the Radeon 9200?
You could probably sell to the Atari Falcon community too for use with CT63 + CTPCI
STMAV340 - Low ON Resistance Quad, SPDT, Wide-Bandwidth Video Switch
- supports resolutions up to 2048 x 1536 @60Hz
- 300 MHz video bandwidth
first i must make a testrun with the new design ...

Hiya Ratte,
Look good but I still don't know why Jens/AmigaKit didn't want to pick this one up???

Jens has gotten to the point where he does not allow any "non-Jens" third party hardware inside the Amiga if you want to have your warranty.
Thats wrong.Perhaps, perhaps not - I really don't care about warranties anyhow (faster and easier to buy new), but that's the impression I'm left with after reading many of his posts.
The product will get to expensive.Ever thought of doing a _really_ cheap version with just the plate and connectors, for people with A1200/A600 who do not need a switch, but just some steady solution for the VGA port from Indivision? That's all I need anyways. :)
have not been following your project. when you say automatic switch is this done *completely* in hardware?
or in-order to operate the above unit automatically you need to install software for it to operate automatically?
what are the three contact pins for?
My question may seem simplistic, but seeing the pics of your new board I have the surprise the professional quality of the printed circuit/board, how or what you use for that finishing technique? because I'm electronic fan with studies and always I want make this boards, instead of home solutions with copper plate and homemade acid.
All other stuff is ordered at "Digi-Key" (because they are to only known distributer for the STAMV340-IC)
the three pins are Select, Vcc , GND, all these lines are going to a 8520 CIA
you need a little tool in the startup-sequence, this tool detects the currently activ screenmode and controles the switch.

early prototype for softwaredevelopment
Can two work together? I have a setup with native RGB out, CV64/3D and Voodoo 3 through Prometheus, and it sure would be nice to have it automatically switch between active screens.

The Eyetech isnt automatic ... you will have to switch manual.

There was an automatic version for CV64/3D - I have two of them.
Retina V-Code Switch is limited to the V-Code Module of the Retina.
The V-Code is converting the Retina Image to S-VHS and Composite-Video.
The V-Code Switch is an Extension for the Extension (Sandwitch) for the Retina.
And it works only with 15kHz Modes and needs min. Retina Software V2.2
But for your information ... I allready played with this idea.
Jens also gave me the H&V-Sync hint.
You can see a separate 10pin header on the special Radeon-Switch (next to the extra manual switch connector).

They are delivering H&V-Syncs, Vcc, GND and the Select-Line.
Specialdesign for prototyping this way ... played with the idea of a Maxim-IC, but it is EOL and I dropped the Idea.
On the other side my software is working like CGFX and P96 did it.
I had the chance to talk with Frank Mariak (CGFX) on a PowerDev-Meeting and the way I controlled the switch is identical to the CGFX-way for Cards with inbuild-switches.
We were snooping the same systemfunction ... the only difference is, that Voodoos, CVPPCs, Radeons didnt have a separate signal line for a switch signal.
So I had to take a signal from the CIA 8520 for this.
And the best choose seems to be the CTS-Signal from the Serial-Port, but it is also possible to use the Select-Line from the Parallel-Port.
But I think that there are more Amigas with parallel printers out there, than Amigas with serial modems ... thanks to LAN and DSL.
MyIf the hsync&vsync signals change to certain value when an amiga screen is being shown perhaps it may be possible to generate the "select line" using some extra logic (the disadvantage would be that circuit would become more complex). Your approach sounds very reasonable for 68k but for OS4 I guess some stuff could be left out of kickstart layout file so it works like 68k version too. Booting MorphOS may be interesting too... does any of your testers have PPC boards?
PS: what's that PaulaPlus stuff in one of your videos? :-)
PaulaPlus is a joke .. like the complete DONOP movie. :D
Regarding the H&V-Sync, the idea isnt bad. I loved the idea, too.
But searching for some shematics or ready-to-use DPMS-ICs showed off some problems.
These ICs take a while to switch the signal, DMPS allways waits some seconds before the signal will be switched.
Sitting in front of an Amiga and waiting for arround 5 sec. for a screenchange isnt very funny ...
PPC development isnt possible for me, my CSPPC got lost at Vesalia in 2001.
I have no change to get some HW back (I tried many times).
For those OSes (also 68kDebian or LinuxAPUS) you can add a manual switch, to override the "software" setting.
(1-0-1 switch = software controlled - hardwired aga - hardwired gfx)
a handfull of samples is finally ready ...
(http://www.amiga.org/gallery/images/4308/medium/1_MS.jpg)
I promised Amigakit a sample on the "Essen-fair / Germany", alternativ AmigaFuture could print a DIY workshop.
Price for a sample is 85,-Euro + shipping.
I need complete details about the config.
Amiga model
FlickerFixer
Graphiccard
If i get to many requests, i will prefer users who wants to write a review and still have some references.
NOTE: The switch is taking a signal from the serial port. The current MAS-Player software is hw-banging the ports, this can cause problems!

there are currently certain folk on this site who claim that someone working from home or a garage, can't in this day and age compete or create such products as you seem to be doing. :)
Send your request to FOLLETT (Amigakit), he own a sample for testing.
