Here's a BIN for $110 plus shipping (with OBO) on eBay for a Model F "Bigfoot" terminal keyboard. It has a Lexmark Model M sticker on the back, so the seller is a bit confused as to what he has. :)I spotted that one a few weeks ago, at this point the seller may be open to offers. Really neat board.Show Image(https://i.ebayimg.com/images/g/A6YAAOSww-BaTqES/s-l1600.jpg)
