The layout is like what you find on Siemens boards, with LCtrl, LAlt and Space the same size as on a regular 102-key board. I like that. The lettering contrast looks quite good, too.
The unevenly yellowed keys indicate varying plastic quality (the same can also be found with Dell AT101Ws and their 102-key relatives), and the Enter stabilizer doesn't look too high-tech. That label color... hmm. Anyway, it looks like an average quality rubber dome for the time (maybe '95 to '97), neither cheap junk nor super heavy duty.
