 can't find any info on it from the internet.
 It has a date code of 1989 and was built in Yokahama Japan, by who I
 don't know.
 Does anyone know who DEC had build there CRT monitors back then? Are
 schematics available?
 
 I have a VR297-D3 which is actually a Sony GDM-1602.  These details
 are written on the label on the back of my monitor though so I guess
 they aren't on yours.

I went and looked again.? Hoped to find some other numbers, besides the
UL and SA numbers I noticed a script S followed by CM 25100M.
This is a high resolution black/white monochrome 15 inch monitor from
1989.? I think that was the cat's meow back then.? It was the low end of the
DEC monitors available for the Vax Stations.?? I opened it up last year
and it is built like a tank, don't remember any obvious OEM logos.
