I finished building the first prototype of my 7X03 extender/load plugin. I have verififed that its extender function works and am ready to try the min-load function. I have 2 working 7704As and a 7514 to try it on. My goal is to be able to power up the 7704A acquisition unit without the display unit. I want it to be able useful as a min load with the other mainframes. It would be used by itself with full mainframes.
The loads are switched in and out by a 8pdt rotary switch. The +5V and Lamp power have a 4 ohm load on each. The 15V lines each have 20 ohm loads and the 50V lines each have 500ohm loads. Each power has a 10ma led load. The total power with the load inserted should be about 47watts.
Is there a file somewhere that list the power usage of each plugin?
I would like advice on the wisdom of offering this plugin for sale. I think it would be a very useful tool but could be a problem with unwise use. I worry what would happen if someone uses the extender in a mainframe with 3 other plugins and inserts the loads.
I have 2 7X01 extenders that have been my shops models for the last year or so. They are now available as I will keep the first 2 7X03s. I offer them for $100 each plus shipping. They are the same as the 10 7X02s I sold last year but have black faces with white letters and no woven cover for the cable.
