Best Way To Handle A Voyager Wobble?

[Steve Simpkin]

Regarding this subject. The hardware and software design of the HP-48SX can be found in the June 1991 issue of Hewlett packard Journal magazine. It is a great read for an example of the extreme design effort that HP put into their products at the time.

From page 31:
"Completing the HP-48SX package are four molded feet, which are sculptured to conform to the bottom case radius. The feet are press fit into the bottom case while it is still warm at the molding machine. A small bump on each foot provides compliance so that the HP-48SX will resist rocking even if the surface is slightly uneven."

Here is a link to a PDF of that edition.
