88u? I have 86 and 87
You're obviously missing the perfect continuation to your collection then - you could say you have Realforce 86-88
The 88 is UK ISO layout. As a scandinavian, I was always missing the extra keys next to enter and left shift, especially since my work laptop I need to use 8 hours a day has that layout.
Too bad there are almost no custom keycaps available for Topre, and even less for the 88-key version, as left shift for example is different width. I'd like to have some retro coloring, but seems like I need to purchase a Cherry MX KB for that...
