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.

Nice find.

Great Card

nice find. What makes you think it needs repair?

[Kroll]

Yes, because my friend find this card a few years ago test with NVDI drivers and he is sure this card does not work and send it to our friend, who is a good electronic man, He will be test on TT but we need drivers. On the beginning he will be try using NVDI drivers.

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.

I think it says "TT-SVGA Main Electronics" on the bottom.

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 ?

[Kroll]

Frank: Additional better photo, Is that what you asked?

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

I have just test it this card on my TT, I tried with all dirvers (T0 and etc) from Idek web site, but not working, The last thing maybe NVDI ET4000 will be help. Can you send me this version of NVDI

There is NVDI 5 -> http://www.s212939144.websitehome.co.uk/awarez/

In the VMG Program you must set the right address ...

[Kroll]

Thanks, I run VMG-4000 and I found:
Screenbaseaddress : $ FEC00000
Registerbaseaddress: $ FED003B0
I do not know what to type:

[frank.lukas]

Set for example a CrazyDots or a Mega4000 Graphic Adapter and play with the different address areas ...

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

[artik-wroc]

Hello Frank
Imagine/NOVA driver for ET4000

[frank.lukas]

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/

[Kroll]

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?

[frank.lukas]

Maybe you need the Atari TT Nova T6 ET4000 Driver ?

I upload it when I back home ...

[lp]

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.

[czietz]

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

Ah, learn something new everyday. Cheers.
