Sounds like my Blue Alps. I'd say they are.
That seems right to me. The sound of the switches in your video is roughly right -- your switches sound a little more hollow than my white Alps, but that probably has to do with differences in the enclosure. With Alps switches that I've used, you generally get a tiny amount of travel before you hit the bump where the key registers; then there's a significant amount of additional travel before you bottom out. There's a light click at the bump, and a louder thunk when you hit bottom. They're generally quieter than unmodded Cherry MX switches, and to me they have a softer, floating feel compared to MX. They're also pretty durable, so there's a good chance the board is still fully operational.
I was expecting a set of dip switches because all my old boards have that, but I see from your photo that this board is simpler -- any configuration you want so long as it's A or X.
Does the board have a cable?
That description is spot on!
Short travel, click, long travel, thump!
It does, it's a DIN connection so I'm waiting for an adapter to try it out!
Took all the caps off now! one crack on one of the switches (top part, the plastic so i think some superglue will do the trick) and one broken part of the cap still inside one of the switches, otherwise, perfect condition!
Needs a bit of cleaning tough..so I'm soaking the caps in soapy water overnight.
