Editing NCR 4950 (section)

==Description==
Internally the keyboard seems to be capable of speaking either an ADDS terminal protocol or standard PC AT, depending on how it was configured at the factory; the configuration is set using wire links on the controller PCB.  With the PC/AT-configured model, a simple rewiring of the cable to a 5-pin connector will make the keyboard usable with a modern computer with the assist of a PC AT/USB [[converter]].

The keyboard features a custom layout with no navigation cluster, but a numeric keypad is included.  A horizontal space for a function key template resides at the top.

Two Hi-Tek switch types have been found: two-eye white (shown below) and two-eye black switches that seem to have had the click arm omitted to provide a linear feel.<ref>geekhack — [https://geekhack.org/index.php?topic=37495.0 Hurricane Sandy Keyboard Sale]</ref> There are two other variants using Omrons and SKCL green switches respectively.
