It was designed and built by Brother - originally for their knitting /
sewing machines I believe. The fact that Tandy adopted it actually seems a
bit weird to me, but I guess they needed something and the serial interface
was easy enough to adapt. The usage on the Z88 certainly is not a
manufacturer-specified odd-on -- just something someone in the community
came up with.
