I think I will go with a Hasu Alps64 rather than trying to desolder a V60. Now to find a source board for blue Alps that I won't feel too guilty about desoldering . . . .
I'd like one too.
I have boards I could kill for Alps, but customs < quality vintages in my eyes. Unless the boards are really common, relatively speaking, or have no intrigue. Like the Striped Amber and SKCL Brown Tandem terminal keyboards I have aren't spared in the same way I spare the Xeroxes from desoldering, mainly because I... Well, it's subjective, I guess, but I think the Xerox boards are too elegant to desolder like that.
The Tandems were just terminal keyboards and their layout expresses that. IMO, they are better suited to be reborn in something modern and custom. I also enjoy SKCLs a bit more in a modern chassis than I do their original chassis, whereas I can take tactiles and clickies in their original housings just fine.
I mean, linears aren't bad in their original cases, but eh.
