Cherry G80-0778
Cherry MX Black, Double-shot keycaps, 1986(?)
A very lucky eBay find. I assume this is the keyboard series Cherry sold for rack-mounting use before they eventually came up with the G80-1800 series in around 1990. The board originally came mounted in a full aluminium case drawer, ready to be mounted in any a default server rack.
The layout is rather obscure, being a mix between PC-AT and some terminal variants. They were likely intended for a non-unix system, due to the lack of various important keys.
The keycaps are the default vintage Cherry double shot keys. Keyboard uses plate mounted Cherry MX Black with Diodes. Although I can't get the keyboard working, it is reported to feature full n-key rollover.
