It is a Tseng Labs ET4000 version, can't see what specific version, but as a driver I would try MVDI v5 first and select ET4000 as graphics adapter during installation.

Someone keen with chips should be able to determine how much ram is on the board by the chip numbers. As its not densely populated I'd guess it might be monochrome or 16 color card. There is some writing on the back as well but the image resolution is to low to read it. Readers here might have trouble helping due to image quality.

There are eight RAM-chips, V53C104AP70. So this is a 1Mb card. That means 1024x768 in 256 colours or 800x600 in 16 bit.

To use NVDI ET4000 or NVDI5 with this card to find the right memory Address space and the I/O Address is the Ticky bit ...

Is there a Adressdecoder GAL/PAL on the Card ?

There's a GAL 20V8 in the middle and a PAL 16V8 to the right of the GAL.

Hello artik-wroc, can you ask for Driver Software or Details with NVDI in the Poland Forum ?

Thanks ...

Who was the Maker? And it is possible to have the Gerber/PCB Layout and the JED Files from the two GALs?


Hello Kroll, try the Nova Driver from T0 until T8 and find the right one. I think a T8 is fine -> https://silicon-heaven.org/atari/nova/

Yes I tried with all drivers from this website additionally VMG-4000 from NVDI.
For drivers for Atari TT from T0 until T8 give some effects. If you run emulator.prg or vmg.prg from these archive, the monitor connected to this card gets some signal (can sync) on the screen in each case gets the so-called "color snow" and that's all.
What do you think, but I'm afraid that the card is damaged?

Only thing I can find with google: is http://atariki.krap.pl/index.php/Magic_Screen
Hints at 2 versions of the card and uses the Imagine driver. Where to find this driver I have no clue.

Imagine is just an older name for the Nova graphic cards.
