"The HP-29C, codenamed "Bonnie", was the last model in the Woodstock family or "Series 20". The codename bears no relation to the previous names of Series 20 models, which were all named after vegetables. In contrast, the HP-29C was followed by a printing version, the HP-19C, and these two were called Bonnie and Clyde. Or does someone know of a vegetable called Bonnie?" Wlodek Mier-Jedrzejowicz.
