I own a G84-4100PPMIT
And a G80-3422LAMIT
I bought this one on eBay.
Originally it featured Cherry MX Black switches and a Linear Gray for the spacebar.
I replaced the modifiers with red switches and the locks with clicky stems and MX black springs (I believe they would be called Ghetto Greens).
It also features a 5 pin DIN cable but I replaced it with a spare PS/2 one (by spare I mean ripped off a dead membrane keyboard).
Keycaps are Cherry profile, lasered with mixed legends. Some are italian, others are just numbers. Don't ask me why it's like that because I have no idea and the only informations I found about this keyboard were on DT and GH.
