I have been working for about 6 months on making steampunk keyboards from solely MODEL M's...A lot of these steampunkers use cheap keyboards that have a square plunger and are usually rubber dome. A couple people use Model M's, but I think they are more difficult to mount the keys on. Although the dual key cap system makes it decently easy enough.
Model M vs Rubber Dome with royal keys is a serious no brainer.
Anyways, my designs include painted cases and ROYAL TOMBSTONE KEYS. I plan on selling them on ebay once I have perfected my methodology. I'm glad this one is selling for 750$
I have already spent a few k in tools and resources.
These keys are very comfortable, however after a short time, I get paranoid that I can feel the glass on my fingers. Them being like 40+ years old, its a weird experience haha
