The reset line for the F-11 (just looked it up, it's not an LSI-11) 
would be useful to know now. I'll continue looking.

But even then I don't have a proper monitor for it! I've got a 21" RGB 
for my VAXstation 4000-60 but I doubt it'll handle the resolution of 
the 350. I've got the video and keyboard cable for the 350 however. I 
won't try it until someone gives me the all clear.

Thanks,

Alexis.
