The first is an Ortek MCK-101FT. I've had a couple of MCK-101s and they're one of my favorite cheap Alps based boards due to the interesting design and nice keycaps. These are pretty common, but normally the SX (SKCM white) or FX (clicky Alps clones), and I've not seen this FT variant before. This one has linear green clones which appear to be Hua Jie AK, notable because the vast majority of these boards appear to be clicky. The switches are light and smooth, but quite loud and not a refined as genuine Alps. This also has a quite low serial, and a warranty sticker from 1993.
I bought this one as is, but the case is extremely brittle, and I've seen lots of these that have been destroyed like this, so as a quick PSA, if you're getting a JX keyboard shipped, make sure it is EXTREMELY well packed. Also, if anyone happens to have a JX case or even parts of a shipping damaged case, I'm on the hunt.
