I've been a resident of AZ since college. Bowmar had a division in Chandler, AZ, but was actually a multinational corporation... IIRC based in Canada. I think only the US operations went bankrupt. My general bet would be that Bowmar (US) was incorporated in Delaware. ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

Last time one of my engineers wanted a copy we paid a few hundred but that was more than ten years ago. Way back when I used ECA224 and IIRC that flowed into EWB but I have to say I wasn't too impressed with EWB in the late 90's. > But not so much the learning curve. > Besides i detest doing anything twice without serious specific need/requirement. > Yep, same here, if something works for ya don't change it.
