Well, they did post several times that they do, including the most recent post from Feb 24, 2015, so I guess they are. Only it takes more than a year now. :-(
There was an update on M83 on the 24th of February on Unicomp Facebook page (

“TenKeyLess Update: We are working on a tenkeyless keyboard, however, it is taking longer than anticipated. Look for more news on it in the next several months. Thanks for your patience!”
You should be able to just rearrange the keys, right? I don't know for sure if you can take keys off of buckling springs, but I'm pretty sure you can...in which case, you'll be fine. Just change the keyboard setting in whatever OS you use.
