Hi Ed, This particular keyboard uses beam spring key switches. These are considered ultra luxury old-school key switches with really good key caps. IBM spared no expense. The IBM 3101 is the thinnest beam spring keyboard and looks closest to the IBM Model M (sort of) in terms of keys. While the key caps don't match up, someone created a converter that makes these keyboards work via USB (replacing the controller board) which also maps out easily to a usable PC keyboard. It is likely to go higher.
I have one of these keyboards that is in serious need of restoration but when I restore it I will acquire a 3101 terminal for it to mate with (as I have done with other keyboards and terminals). Hope this helps. Santo On Fri, Oct 19, 2018 at 12:15 PM ED SHARPE via cctalk <cctalk@classiccmp.org> wrote: > OK I am sorry I do not understand why the keyboard went this high? > > Please...
