The GH60 and DZ60 supported both ANSI and ISO.
The DZ60 also supports uniform 0.25u staggering and arrow keys like the MiniLa, but not the MiniLa's modifiers and centred small space bar — instead, the space bar is split (which I think is better).
I think the GH60 also supported a Cherry 6u space bar (offset stem), which is nice if you use 1.5u mods but want the right Alt key in the right spot.
BTW. The GH60 also had a header for a possible expansion (numpad or whatever) but I haven't seen anyone build anything that used it.
Perhaps OP can just change the title of this thread to "a 60% keyboard pcb, the first product of my new company"
It's kind of a big word to replace something. But also in terms of what? Market-share? Functionality?
In order to *replace* a change product / community effort, I expect the capability and functionality and quality of such a new product *at least* matches the target(s) meant to be replaced.
Findecanor has just mentioned only a few of the missing layout capability, and I won't start with other functions such as LED / underglow LEDs...
Good luck with your new company and this new product. And good luck with marketing.
