Anybody using an 83 key IBM model M keyboard with a modern PC? Clickykeyboards.com has info about a key codes adapter here: http://www.clickykeyboards.com/index.cfm/fa/items.main/parentcat/11298/subcatid/0/id/500722 Was wondering if anyone is a fan of the old 83 key keyboards and if there any glitches when using one of these adapters, i.e., limits on maximum typing speed.
