This is an IBM 4683 matrix keyboard. It's from '80s, the internal assembly is made by Key Tronic for IBM. It also included a template kit and ‘windows’ for use with making labels for the keycaps.

[It] uses Key Tronic’s Foam & Foil capacitive switches – supposed to be the tactile variant but it actually feels like very stiff linears – SharktasticA

The IBM 4683 is noteworthy for being the first PC/'x86'-based point of sale retail system from the company and for being a large vintage ortholinear keyboard/macropad, although even earlier ortho keyboards from IBM are known, such as the 254-key IBM Multi-Shift Kanji Keyboards of the '70s.

(This was succeeded by the IBM Model M11 Modifiable Layout Keyboard in 1993, which was a dome with slider keyboard with an integrated magnetic stripe reader.)
