Would you be so kind to explain a bit about the hm
version of MH.
Not sure what Clem meant but I used "hm" by Jim Guyton (@Rand) on my
Fortune box until I retired it. It provided a 2D interface. Later I
tried xmh but didn't like it.
The early history of MH is covered in some detail in Willis Ware's "RAND
and the Information Evolution" book from page 128 onward. hm & Guyton
get a paragraph on page 136.
