I finally got one! A square badge industrial. It was not in very good condition (bottom case was cracked and missing parts of it). But the top case was in perfect condition. And I had a spare bottom industrial case that I got from Unicomp (it is a Lexmark-made part, but Unicomp used to sell them). So no it will not be completely original, but I have the part I care about which is that top square badge industrial cover.
Enjoy the pictures!
Beautiful work, that board looks great! Makes me want to clean a really dirty one I have under my bed at the moment.
That square IBM logo. That's what it's all about man. Keycap(especially start/stop keys) are great too but the IBM logo is the best iteration of it imo.
Redmaus It absolutely is! I will cherish it forever.
