I suspect you'd also have to work on whatever Z-machine implementation 
you use to actually make it use both ANSI color control, and also user 
defined fonts. And then, of course, you need a font.

I don't think you want to go down that path. :-)

I did say "primitive" graphics. Beyond Zork uses font 3 to play with 
some crude graphics. Basically mapping, and some bar charts and nice 
framing.
And, of course, it uses color if possible.

But if you are interested, I can send you my Z-machine font definitions 
for the VT200, VT200, VT400 and VT500 terminals, so you don't have to 
define those yourself.

As for playing, if you just have a VT525, it's easy to test, by just 
logging in to Mim.Update.UU.SE, and play any Infocom game on that 
machine. My Z-machine for the PDP-11 do handle the font and color stuff 
for the VT terminals (of course). :-)
