Calling all small keyboards

[Robert Howard]

Not sure if this helps but look at patent 5700097 http:// 
patft.uspto.gov/netacgi/nph-Parser? 
Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO% 
2Fsrchnum.htm&r=1&f=G&l=50&s1=5700097.PN.&OS=PN/5700097&RS=PN/5700097

It may lead to something else via the patents it references including  
a Japanese patent from 1983
