Just about anything marked "TOP SECRET" must be cool : ).

You should, actually, be able to connect it to a composite NTSC monitor. The
sync rates are the same as or very close to those used on USA analog TV
signals. That's what I used for a display on my PRO 380.

Most apps on the PRO 380 expected you to use the video console, with the
possible exception of some debuggers, and custom SYSGEN'd copies of RT11 (or
any other DEC OS's that'd run on it). Bascially, you'll want to use a
keyboard and monitor, not a serial console.
