HP41CV/Kern Surveying Instruments - William Lafferty - 03-23-2006 I am trying to construct a display showing the advancements made by the now defunct Swiss surveying firm Kern with electronic theodolites some time ago. I have an E2 electronic theodolite and EDM, and the DIF41 attachment which enables the theodolite to send data to and receive data from a HP41CV.
I can transfer data from the E2 into the HP41CV registers fine, but I cannot seem to transmit data from the HP41CV to the E2. The instructions in the manuals do not help. They simply refer to a "HP41 program on magnetic card" but to date I have been unable to locate such a program. And the only instructions given seem to be in BASIC language. They are The manual also says that anything transmitted to the E2 from the HP41 must be in the X register. If anyone has any knowledge of this, could they please contact me direct on wjlafferty@ozemail.com.au
thanks .....Bill Lafferty
