While the Moniterm Viking is full-size 19", the A2024 is only 14". Much lower price, though, about the same as a VGA screen. The internal workings is not important, what is important however is that the monitor will give you 1008x1024 (or 1008x800 in NTSC) in four gray scales. If all you want is 512 pixels in the Y direction you could try something else: Switch your A3000 to PAL with the PAL/NTSC jumper. You would probably also have to edit some files under UNIX to get the OS to understand that you have switched settings.

Not really, it can do twice the normal horisontal resoultion, but you _must_ switch the de-interlacer off manually, and besides I dont think UNIX supports that mode.

Is it possible to get the Amiga video chips to do 800x600 monochrome? How about 4 or 16 color? I'd like to be able to have at least 512 points in the Y direction under X with stock hardware. I suppose I'll just end up growing spider webs till the A2410 is available. B^(. By the way, what's the best book for finding out exactly what memory registers to tickle to access video and sound on the Amiga? Don't seem to be many .h files with helpful hints.

Close anyway... The SuperHighRes modes (1280x200 and 1280x400) don't require a special monitor. The 1080 I have on my 2000 works just fine. Better in fact than running it through one of the deinterlacers, since the monitor seems to do just fine with 35ns pixels. the modes that require a multisync or VGA monitor are the Productivity modes, 640x480 and 640x960 interlaced. With either of these types of modes you get at most 4 colors from a palette of 64. And with overscan, even on an NTSC machine, you can push the size by quite a bit.
