Sure it is. I'm driving this one from an Amiga 2000, right off the mono RCA
jack on the back. I made a cable with a DB-15 connector for the VR-201 end
and an RCA jack and HDD power socket for the Amiga end. I fire up the Amiga
to see the animation of the kickstart disk self-inserting.

Front and back porch timing I can perhaps see. There is no seperate sync
on a VR201. It has a pin for Mono Composite In. I'd post the pin-out, but
it's at home and I'm not.

I realize that the VR-201 is not generic, but it is handy when I need a
mono monitor in a semi-portable situation (I once took my A2000 in the
Bomac tower case to an Amiga show in Columbus and ran it with this VR-201
to save space)
