I recently bought this Cherry G80 keyboard from eBay since it came with a Beige ISO-IT keyset, albeit in a grime condition.
It features a Zenith logo on the top right of the upper half, although there's no mention of the company on the backside label.
Despite having an X as layout in the article number code, it undoubtedly features and Italian ISO keyset, which is the main reason for me buying this keyboard.
Also, by the code, I can tell it was made between October 15 and 21, 1990.

It features Cherry MX Black switches with diodes, hence probably NKRO. It's a multiprotocol keyboard given the DIP switch on the bottom side.

As stated, both keycaps and case were in poor condition. There were pen marks on some keycaps and dirt all around the keyboard. Nothing than a good soapy bath couldn't fix.

No wonder the keyboard was so heavy. There's a 4mm thick iron bar screwed on the bottom half of the case.

One thing that quickly caught my eyes was the PCB mounting prongs, which are basically the same of any other G80 case, hence the case would accomodate a
GH80-3000 PCB.
For this reason I didn't even bother testing the original PCB, at least for the time being.
Strangely enough, there's an opening in the shell that aligns perfectly with the USB port of my PCB.

Then I
quickly put a PCB together and flashed the firwmare.
Forgive the black cable but I ran out of beige ones. It's temporary and will be surely replaced in the future.
As you can tell, switches are Cherry MX Silent Blacks.

I gotta say this case feels very sturdy and it's way better than any 3000 case I've came across so far.
Final result.
