Well the 510 I got just arrived... turns out to be brown dyesub with orange sublegends. The base color is of course yet a different color than anything else I have
More of those awesome linear white switches though, so I am still pretty pleased. Now I just need to do a good cleaning.
Unfortunately the typewriter didn't make it, arrived smashed to bits. But, that's fine as it saved me a good deal of time disassemble to pull the switch pcb.
I don't see how using these alphas and other modifier is any worse than the oldschool white with beige modifiers doubleshot sets. Same thing.
