The Filco keyboards, and especially Filco Majestouch and Majestouch TKL had a role in kickstarting the mechanical keyboard hobby.
Back in 2010 when I registered here, it was one of the few widely available contemporary mechanical keyboards you could buy.
It was only available with black, brown or blue Cherry MX switches back then, in a cheap plastic build like most office keyboards of the time. But most other keyboards discussed here back then were vintage models.

Not long after, the keyboard market exploded with many competitors offering less expensive keyboards.
A lot of evolution has happened in the commercial keyboard market since then.
FILCO never kept pace or reduced their price that much, although, in 2023, they did release a split 60%.

Earlier, they have also rebranded keyboards from Strong Man and Ortek. One notable keyboard was a Alps keyboard with colourful keys shaped like a dinosaur: the Filco SMK-8851 Dino Kaijū.

User Bpiphany (previously known as "PrinceValium") had designad replacement innards with programmable controller for the Majestouch TKL: the Phantom. When designing the plates, he also invented cutouts for opening Cherry MX switches from the top without desoldering.
He also made replacement controllers for the Majestouch and a few other keyboards.
I never had a FIlco myself, but I bought a Phantom set that I built a beige retro-case around, and it has stayed my daily driver at home for 10+ years, and also built a 70% from a cut-down Phantom plate.

Honestly not surprised they couldn't keep up with how much the market shifted toward custom hotswap stuff and crazy budget options over the last few years, but those old Filcos were built like tanks. Mine still works like new sitting in a closet somewhere.

If the issue is with keys not registering, I’d start by testing the switches individually and checking the solder joints around the affected keys. A loose or cracked joint is pretty easy to miss, and touching it up can sometimes fix the problem right away.

THis is a cool colourway re-imagined. Classic, Grey / cream / orange combo works well. Fun novelties. Good luck with the IC
