As some people expected, it's a dome with slider (thank god it's not F&F ). I never had one of those type of boards, but this one feels great, I'm kinda surprised. Sharp, tactile bump and very snappy. Light keyfeel (spacebar is maybe even a little too light, if you ask me). You don't have to fully bottom out to register a keypress. It's not scratchy or bindy, like not at all, which is also kinda surprising considering the age and condition of the board.
It runs on some kind of XT-protocol and works via Hasu's XT-converter (God bless this man). Keycaps are thin PBT with a grey print and a black front-print on a few of them. Cross mount and MX compatible. One single, lonely locklight on the Capslock key. They did it the lazy way and stabilized only the spacebar and went with stepped keys on the rest. I don't mind it, since I've always liked the looks of stepped keys, but I'll never get used to that Enter key
Build quality in general is giving me mixed feelings. You could say it's built different .
On the one hand there's a good amount of metal in the board. It seems though that all that metal used for the chassis and so on is aluminium which makes it feel kinda light and cheap. It has an Aluminium back panel with some sort of enamel coating, plastic top housing and another aluminium sheet on which the membrane assembly is glued on. The glue/foam is peeling off or even disintegrating on some spots but it seems this doesn't affect the performance of the board, yet. This plate is bolted together from two smaller sheets, but only on the top, leaving room for flexing/bending at the bottom part. The slider assemblies are fixed to the plate with plastic rivets, but fortunately nothing has come loose yet.
The spacebar seems to like to get stuck which could be because of the age and the grime, so let's see whether I can fix that or not.
I'm in the process of cleaning it right now, will add more pictures later.
