History
More
The unsaver layout was originally featured on the IBM 3290 Model 1 keyboard and to my knowledge predates the more common 122 layout. IBM's boards featuring the layout have always been highly desired in the hobby and back in the early 2010s there were a few Cherry G80-2*** boards modified to have the unsaver layout. The first time I saw one of these customized boards I was amazed and started looking for a way for me to obtain them. With minimal luck and no good alternative available I started drafting the 21xx design back in 2021. It took a few years but suddenly I had a prototype on hand and a lot of people showing interest so I decided to perfect the design to my tastes hoping to one day be able to offer it to everyone.
Thanks to Shark for having a great wiki on IBM keyboards that let me check what came first
Old prototype pictures.
Please note that the design and colors have been adjusted, the blue will be slightly different on group buy boards.More
