C= 1084 monitor w/ Acorn Archimedes?

Hi,

Some earlier Acorn-branded monitors were pretty much the same as the 108x CBM-branded ones.

Later ones that were sold with Archimedes hardware, e.g. the computer-in-a-keyboard A500-style range like the A3xx series, were sometimes rebadged Microvitecs and as such are multisyncs.

The Microvitec 1483 works fine on both the Archie and the A1200, displaying a range of screenmodes.

If in doubt, check! You don't really want to be supplying out of range signals to early monitors!

Also note, you can tell the Archimedes to use a 15KHz screenmode at boot time. Haven't dug mine out for a while so I can't remember exact details, but have a look at the "*CONFIGURE" command's many parameters.

Hi,

You could try building your own cable...

Pinouts for the Archie's video output can be found here and here, and the 1084's video input can be found here and here.

The Archie's 15KHz screenmodes should be OK with the 1084 but if in doubt, check! And as I mentioned above, don't let the Archimedes supply anything other than a 15KHz display to the 1084 or it could end up as toast!
