Yeah, I shoulda been a little clearer on this. I'm referring to the
text mode of the graphics board (the 1280x1024 256-color single-
monitor one,) as run from the VMS command line. I do have terminals I
could use over the serial port, I'd just like to be able to use the
one that already exists in the machine if possible. The exact nature
of the problem is that I tried to start up EVE/TPU, but it was
complaining because it didn't know what kind of terminal it was
talking to. If the built-in text mode really is a dumb terminal,
though, I suppose it's pointless trying to get a screen editor working
on it in the first place, and I'll just leave off with that until I
get DECWindows up and running. (VT52 compatibility would be better
than nothing, but it looks from the EVE manual like it basically
expects a VT100.)

Yeah, I'm in the middle of working on that; I got the installation kit
onto the machine, but it's complaining that the kit is "too large for
the application's buffer." I've seen advice elsewhere that this may
stem from my having unzipped it prior to copying rather than directly
on the VAX, so I've gotta burn a new CD with the ZIP archive and give
that a shot.
