Isn't this using the Hitachi ACRTC HD63484P8 ?

You need most likely specific application support for it.

Yes it uses that chip. The man who found it says, that there were drivers for the Viking for Windows/286, Windows/386 and Win 3.0. About Win 3.1 he is ot sure - but many DOS applications had drivers of this device, like Ventura Publisher, Autocads of the age and so on...

Giving this thread a massive bump! There isn't much information about these anywhere online, so I figured I'd post here in case the OP is subbed to the thread.

I managed to obtain a Moniterm Viking like the one pictured in the OP (minus the big red sticker on the HD63484P8 chip), and I would love to be able to do something with it.

Has anyone ever located any drivers for it?

Also, this thread mentioned that the display output on it is an ECL interface and that the Atari ST community has adapters to use them on a VGA monitor. Does anyone know if that is true? I can't find any other references to Moniterm Viking and ECL elsewhere online, but I haven't looked a ton yet. There is such an adapter here, and I don't know if it's the same thing but there is one for Sun computers here as well.

aaannnd... I got a MicroChannel version of this card for the IBM PS/2 in the same lot, which is super awesome and apparently even more rare. I will post pics of them later if there is any interest. I have a PS/2 Model 90 but I have a feeling that the onboard XGA graphics is a lot more up to date than this so it would be a strange addition to the system... still, maybe I could at least test it. 😀

There's a driver in the Windows 1 driver pack- VIKINGI.DRV found in V1DSK.ZIP, for example at http://cd.textfiles.com/carousel/030A/ so you may be able to bring up Windows 1.04. According to the manual there used to be Ventura / GEM drivers as well, but I've never seen those.

The Windows driver has support for a configuration file, C:\VIKINGI.CFG. This file can contain a line beginning 'M' which gives the I/O port base address (default 03E8h) and another beginning 'T' which I don't know what it does.

Oh, nice! Thank you for finding those! The readme file in V1DSK2.ZIP does mention that these are Moniterm Viking 1 drivers, so that's very cool. The zips also contain drivers for some other really early video cards. I will add the zips here and post the list of video drivers in case anyone is ever searching for these:

Conographics ConoVision 1440 *
Moniterm Viking I
Sigma Color 400
STB HT Chauffer *
STB Multi Res *
Tseng EVA
Video-7 Vega Deluxe with NEC Multisync Enhanced Color display
Vermont Microsystems Inc. Image Manager 1024
Wyse WY-700 High Resolution Display Adapter

The OP of this thread seems to have posted over at VCfed back too back in 2016, and there were some good replies there too.

Sadly, no sign of the Windows 3.0 beta driver that someone on Usenet mentioned getting from Moniterm back in 1990. Sure would be nice to stumble upon that in the dark corners of the internet.

I would still have to figure out how to get this connected to an SVGA display though. I haven't found any more details about whether this is the same "ECL" interface used by the Atari or Sun adapters linked to earlier.
