I don't know if this is quite the info you're after, but I'll try.
Some time ago I got a microvitec 14 inch screen from a local school they were using with archie's. The sticker on the back says "Manufactured for Acorn Computers".
With the help of a gender changer, it worked fine on my 500. Inside it looks very much like an early 1080, or 1084. It even suffers from the power switch problem suffered by some amiga monitors.
Seems worth a try :-)
