Hi, I need to be able to take the monitor O/P of a old Strand Light Palette
90 as per
http://strandarchive.co.uk/control/c_memory/lightpalette90/lp90.html that
has is TTL level RGB and presented via a 9pin D type out to a couple of flat
screens. I understand the two technologies are not compatible. Can anybody
give me advise on how i can achieve this if at all possible.

Thanks

Andy

You are starting with EGA and need to target VGA. There's a couple of
options here. First would be direct EGA to VGA adapters. They're
probably not going to be cheap.

Be careful that some things listed as CGA-capable are capable of the
scan rates but not the color. A little custom cable construction can
make it so that you at least will not have things be invisible,
provided you have an analog RGB input that can handle the sync rates.

The key thing you will probably be looking for is 25khz sync and TTL
video.

There's nothing fundamentally incompatible about the technologies but the line
and frame rate of the Strand desk's output may be completely incompatible with
moden flat screens designed for PCs. Almost certainly in fact.

Check the syncs with a scope first.

You may find a crt is the only practical option.

I don't use a PC and was surprised to find an LCD monitor will run at
speeds well below its 'official' ones. Some of my apps need 50 Hz, and the
monitor I'm using is happy at this. (*)VGA CRTs are a different matter -
although of course if it's 50 Hz a UK TV might do.
