Holy cow! People are still buying Itanics? That's unbelievable!
Just curious - why run a different port of Lynx when you could run Lynx directly or links? If you're running Lynx (not sure about ELynx), then you can use the "-vikeys" option so you can move around without arrow keys.
In any case, an original Mac makes for a fine retro glass terminal experience. One of these days I'm going to do the same with a Sinclair QL and a VT100 terminal program I wrote back in the 1980s...
